Why use OpenVPN on EdgeRouter?
EdgeRouter devices from Ubiquiti are known for their solid performance with a strong feature set. OpenVPN is a flexible, widely supported VPN protocol. Combined, they give you:

• Strong security with TLS/SSL-based authentication
• Flexible client/server topology for remote access and site-to-site
• Reasonable performance with CPU-friendly encryption options
• Broad compatibility with Windows, macOS, Linux, and mobile clients

Prerequisites and quick checklist
Before you start, gather these:

• EdgeRouter model ER‑Lite, ER‑Lite‑4, ER‑6, etc. with current EdgeOS version
• Internet connection on the EdgeRouter WAN interface
• A public IP or dynamic DNS for your EdgeRouter
• OpenVPN server configuration files for remote access or server-side details for site-to-site
• Certificates/keys: CA certificate, client certificate and key, and TLS-auth if used
• Access to EdgeRouter’s CLI or Web UI Router OS
• A machine to test connectivity laptop or test device

Reminders

• Create backups of your current EdgeRouter config before making changes
• If you’re behind another VPN, ensure port conflicts are avoided
• Check firewall rules to permit OpenVPN traffic UDP or TCP on the chosen port

Part 1: Remote access OpenVPN client setup
This section covers configuring the EdgeRouter to act as an OpenVPN client so individual users can securely connect to your network.

Step-by-step guide

1. Prepare the server details

• Server address public IP or DNS
• Port default 1194 for UDP, 1195 for TCP
• Protocol UDP is common for performance
• TLS/auth options tls-auth or tls-crypt if used
• Authentication method certificate-based is typical

2. Create a VPN user and certificate server side

• If you’re using a centralized PKI, generate:
  • CA certificate
  • Client certificate and key
  • Optional: TLS-auth key
• Export these securely to the client devices

3. Import certificates to EdgeRouter

• In EdgeOS, you’ll place certs in /config/auth/openvpn or a similar directory as required by your setup
• Ensure file permissions are correct readable by the OpenVPN process

4. Configure the OpenVPN client on EdgeRouter

• Access the EdgeRouter via the Web UI or SSH
• Navigate to the VPN section and choose OpenVPN Client
• Fill in:
  • Server address: your OpenVPN server hostname or IP
  • Port: chosen port
  • Protocol: UDP or TCP
  • TLS-auth/crypt: enable if your server uses it
  • Client cert: select the certificate from the local store
  • Client key: attach if required
  • CA certificate: attach
  • Remote network: the network you want accessible from the client e.g., 10.0.0.0/24
  • Local network LAN if needed for routing
• Enable the VPN client and apply changes

5. Set up routing and firewall rules

• Create a policy route to push the OpenVPN subnet to the LAN
• Allow VPN traffic in the firewall: WAN_IN or custom OpenVPN rule set
• Example rule: Permit UDP 1194 or your port to the VPN server
• If you want full-tunnel: push all traffic through VPN
• If you want split-tunnel: only route specific subnets via VPN

6. DNS handling

• Point VPN clients to your internal DNS server or a public DNS if you prefer
• Optionally configure DNSSEC if your server supports it

7. Test connectivity

• From a client device, connect to OpenVPN
• Verify IP is the VPN subnet: check your client’s IP shows as internal, not your public one
• Ping a host on the remote network
• Check whoami on the client device to confirm the route to internal resources

Configuration example remote access

• Server: openvpn.server.example
• Port: 1194
• Protocol: UDP
• TLS: tls-auth enabled
• CA: ca.crt
• Client cert: client1.crt
• Client key: client1.key
• Remote network to access: 10.20.30.0/24
• Local network: 192.168.1.0/24 your EdgeRouter LAN

Verification and troubleshooting

• Check OpenVPN status in EdgeOS: Status -> VPN -> OpenVPN Client
• Look for common errors: certificate mismatch, bad TLS key, or port blocked by firewall
• If the tunnel won’t come up, scan with a packet capture on the EdgeRouter’s WAN and VPN interfaces to confirm traffic is reaching the server
• Ensure the server allows client connections from your remote IP

Part 2: Site-to-site OpenVPN setup
Now for connecting two offices securely. Site-to-site VPN is great when you want the two locations to appear as one network, with devices in each site able to reach resources on the other.

Step-by-step guide

1. Agree on common network schemes

• Site A LAN: 192.168.10.0/24
• Site B LAN: 192.168.20.0/24
• Use non-overlapping subnets to avoid routing issues

2. Server and client roles

• Decide which EdgeRouter will run the server side Site A or Site B
• The other site will run the OpenVPN client in site-to-site mode

3. Prepare PKI

• You’ll need a CA, server certificate, client certificate for the site-to-site connection
• Export server cert, server key, and TLS-auth if used, plus the CA cert

4. EdgeRouter site-to-site OpenVPN server setup Site A

• Create an OpenVPN server instance
• Configure:
  • Protocol: UDP or TCP
  • Port: 1194 or custom
  • Server subnet: 10.8.0.0/24 example
  • Push routes or client-specific configurations for Site B
  • TLS-auth if used
• Add firewall rules to permit OpenVPN on the WAN port
• Add a static route to Site B network via the VPN tunnel

5. EdgeRouter site-to-site OpenVPN client setup Site B

• Create OpenVPN client with the Server Address pointing to Site A
• Client config mirrors server settings
• Map Site B’s LAN 192.168.20.0/24 to Site A’s VPN network 10.8.0.0/24
• Add firewall rules to permit traffic from VPN to LAN and back

6. Routing and NAT

• Ensure proper routing entries exist on both sites so internal subnets can reach each other
• Disable or configure NAT carefully
  • For true site-to-site you typically do not NAT inter-site traffic
  • If NAT is necessary for egress to the Internet, keep local LAN NAT as usual

7. Testing and verification

• Test inter-site pings: from a host on Site A to a host on Site B and vice versa
• Check traceroute to confirm path goes through VPN
• Confirm remote subnets are visible in each site’s routing table

Configuration example site-to-site
Site A OpenVPN server

• Server: 10.8.0.1
• Network: 10.8.0.0/24
• Peers: Site B OpenVPN client

Site B OpenVPN client

• Remote server: siteA.example.com
• Tunnel network: 10.8.0.0/24
• Local network: 192.168.20.0/24
• Peer: 10.8.0.1

Advanced tips
DNS and split tunneling

• If you want only specific subnets to go through VPN split tunneling, configure policy-based routing
• If you want all traffic to go through VPN full tunnel, set a default route through the VPN interface
• For DNS, you can push your internal DNS server to VPN clients or rely on a public DNS
• Consider DNS leakage protection to prevent queries from leaking outside the VPN

Failover and redundancy

• If your EdgeRouter has multiple WANs, you can set up VPN failover so the VPN reconnects automatically on WAN changes
• Use dead-peer detection and keepalive settings to maintain tunnel health
• Consider backup OpenVPN servers for remote access or multiple site tunnels for redundancy

Logging and monitoring

• Enable VPN logs and monitor for authentication failures
• Use VPN status pages in EdgeOS to verify tunnel uptime
• Consider exporting logs to a centralized SIEM or syslog server

Performance considerations and data
Real-world numbers rough estimates, varies by hardware and encryption

• EdgeRouter X or similar: OpenVPN throughput around 60–180 Mbps with AES-128-GCM depending on CPU and traffic patterns
• Encryption impact: OpenVPN with TLS and certificate-based auth may use 1–2x CPU when encrypting at line rate on mid-range edges
• TLS-crypt/TLS-auth: adds minor overhead but improves security and stability
• Remote access scale: for 10–50 concurrent clients, expect minimal impact on a robust EdgeRouter—pin the server to a capable device or load-balance if needed
• Site-to-site: throughput mainly limited by CPU and memory; 100–400 Mbps typical on mid-to-high-end EdgeRouter models when optimized

Table: Quick comparison of remote access vs site-to-site

• Aspect: Remote Access | Site-to-Site
• Use case: Individual users connect remotely | Two sites connect as one network
• Subnet exposure: VPN client subnet to internal network | Internal subnets across sites
• Routing complexity: Moderate user routes | Higher inter-site routing
• DNS handling: Per-client or VPN DNS | Centralized DNS per site
• NAT: Optional per-tunnel NAT rules | Usually no NAT between sites

Table: Common OpenVPN settings to consider

• Encryption: AES-256-CBC vs AES-128-GCM
• Protocol: UDP preferred for performance
• Port: 1194 by default, can be changed to avoid conflicts
• TLS-auth: Optional but recommended
• Compression: Consider disabling to improve security with modern clients
• Persist options: Use persist-tun, persist-key to improve stability

List: Quick checklist for your OpenVPN deployment

• Backup current EdgeRouter configuration
• Gather server/client certificates and keys
• Confirm firewall rules allow OpenVPN traffic
• Configure VPN client/server or site-to-site as needed
• Set up routing rules for VPN subnets
• Configure DNS settings for VPN clients
• Verify tunnel status and test connectivity
• Implement monitoring and logging

Narrative tips and real-world gotchas

• Don’t underestimate certificate management. If you rotate CA or clients, you’ll want a clean process to revoke and reissue certificates without downtime.
• When you’re testing remote access, bring a test device into the remote network to ensure your DNS and routing work as expected.
• For site-to-site, try to keep the tunnel IP range non-overlapping with both LANs and any other VPNs to avoid routing confusion.
• If you’re using dynamic DNS, ensure your EdgeRouter updates the DNS entry when your WAN IP changes, so remote peers can reconnect without manual intervention.

FAQs

Frequently Asked Questions

What is the difference between OpenVPN UDP and TCP on EdgeRouter?

UDP is generally faster and preferred for VPNs because it has lower overhead and less latency. TCP is more reliable over unstable networks but can be slower due to its own congestion control. If you’re unsure, start with UDP.

How do I know if my VPN tunnel is up?

Check the EdgeRouter’s UI under VPN status or use CLI to run show openvpn status or show vpn. Look for “Initialization Sequence Completed” or a similar message indicating the tunnel is established.

Can I run multiple OpenVPN connections on the same EdgeRouter?

Yes, you can run multiple OpenVPN client connections or a mix of client and site-to-site configurations. Ensure you have unique tun interfaces and correct routing rules to prevent conflicts.

How do I test traffic going through the VPN?

From a device on the remote network, ping a device on the other network. Use traceroute to confirm the route is through the VPN. You can also use iperf to measure throughput.

How can I improve VPN performance?

• Choose AES-128-GCM or AES-256-GCM for modern devices for better performance and security
• Route only necessary subnets through VPN if you don’t need full-tunnel traffic
• Use UDP for lower overhead
• Ensure the EdgeRouter firmware is updated to the latest stable release
• If needed, offload encryption to hardware if your hardware supports it

What should I do if the VPN connection drops?

Check your firewall logs for blocked traffic, verify WAN connectivity, and inspect server side logs. Enable automatic reconnect/restart timers and dead-peer detection if supported. Pia vpn edge extension 2026

How do I manage certificates securely?

Store certificates on a secure server and distribute them using a secure channel. Rotate certificates periodically and revoke any compromised keys via the CA.

Can I use OpenVPN with dynamic IP addresses on the server side?

Yes, but you’ll want to use a dynamic DNS service or static public IP for the server endpoint to avoid client connection failures.

How do I enable split tunneling for remote access?

Configure routing so only specific subnets traverse the VPN. In EdgeRouter, this means adding policy-based routes that designate which destinations go through the VPN tunnel and which use the normal Internet path.

What about IPv6?

OpenVPN can transport IPv6, but you’ll need to ensure your EdgeRouter supports IPv6 routing, and your VPN server is configured to handle IPv6 if that’s part of your plan. For many setups, IPv4 is sufficient, but IPv6 can be added if needed.

Section overview

• Part 1: Plan the VPN topology remote access vs site-to-site
• Part 2: Prepare certificates and server config
• Part 3: EdgeRouter OpenVPN client configuration remote access
• Part 4: Site-to-site VPN configuration on EdgeRouter
• Part 5: Routing, NAT, and firewall rules

• Part 7: Troubleshooting common issues
• Part 8: Maintenance and tips

Part 1 — Plan the VPN topology
Remote access mode

• Purpose: Let individual devices on your network connect to a central OpenVPN server.
• Typical setup: One or more VPN clients connect through the EdgeRouter to the OpenVPN server, and the VPN network is assigned to remote clients.

Site-to-site mode VPN tunnel between networks

• Purpose: Connect two or more networks as if they’re on the same LAN.
• Typical setup: EdgeRouter acts as a VPN client that creates a tunnel to a remote gateway. Routes are configured so traffic between the two local networks flows through the tunnel.

Tips Vpn on microsoft edge

• Decide which LANs will be on VPN side e.g., 192.168.1.0/24 on EdgeRouter side and 10.1.0.0/24 on remote side.
• Choose a VPN subnet that won’t overlap with existing LANs to avoid routing conflicts.
• For remote access, plan a client-specific routing or a common VPN pool depending on your server and access requirements.

Part 2 — Prepare certificates and server config

• If your OpenVPN server uses TLS, you’ll need CA, server cert, and client certs/keys. For static keys rare on OpenVPN, you’ll manage a pre-shared key instead.
• Copy or generate the necessary files:
  • ca.crt
  • client.crt
  • client.key
  • ta.key optional for TLS-auth
• If your server uses TLS-auth or TLS-crypt, make sure ta.key is available and configured on both server and client.

Server-side notes brief

• Remote access solution often uses a dedicated client config per user or a single client config for a shared pool.
• For site-to-site, the server needs a static route to your local network or proper push-route handling.

Part 3 — EdgeRouter OpenVPN client configuration remote access
This section covers configuring the EdgeRouter to connect as an OpenVPN client for remote access.

Step 1: Access EdgeRouter

• Log in to the EdgeRouter Web UI or via SSH.
• Confirm your EdgeRouter is running a supported EdgeOS version.

Step 2: Upload certificates to EdgeRouter Proxy in edge: a comprehensive guide to using proxies with Microsoft Edge for privacy, speed, and access

• Place ca.crt, client.crt, client.key, and ta.key in a directory accessible to the router, typically /config/auth/openvpn/.

Step 3: Create the OpenVPN client configuration

• You can create a VPN client config file client.ovpn with the server address, port, protocol tcp/udp, and the correct TLS/auth settings. For EdgeRouter, you’ll translate this into the EdgeOS VPN object syntax rather than using a full .ovpn file.

Recommended configuration style EdgeOS CLI

• The OpenVPN client on EdgeRouter is set up via the System > VPN > OpenVPN client section or via CLI.

CLI example generic, adjust to your paths and server:
set vpn openvpn remoteaccess server ‘your.openvpn.server’
set vpn openvpn remoteaccess port 1194
set vpn openvpn remoteaccess protocol ‘udp’
set vpn openvpn remoteaccess dev-type ‘tun’
set vpn openvpn remoteaccess ca ‘/config/auth/openvpn/ca.crt’
set vpn openvpn remoteaccess cert ‘/config/auth/openvpn/client.crt’
set vpn openvpn remoteaccess key ‘/config/auth/openvpn/client.key’
set vpn openvpn remoteaccess tls-auth ‘/config/auth/openvpn/ta.key’
set vpn openvpn remoteaccess mode ‘client’
set vpn openvpn remoteaccess username ‘optional’ // if server requires user auth
set vpn openvpn remoteaccess password ‘optional’ // if server requires password

• If your server uses tls-auth or tls-crypt, ensure the tls-auth option is enabled and the key path is correct.

Step 4: Define correct routing and IP settings

• Specify the VPN interface name created by EdgeRouter often tun0, but EdgeOS abstracts it.
• You may want to set:
  set vpn openvpn remoteaccess local ‘0.0.0.0’
  set vpn openvpn remoteaccess subnet ‘10.8.0.0/24’ // or your server’s VPN pool
• Depending on server config, you may need to push routes to include your LAN subnets.

Step 5: Enable the VPN client Does hotspot go through vpn and how to secure mobile hotspots with a VPN on iPhone, Android, Windows, and Mac

• Commit and save:
  commit
  save
• Check status:
  show vpn openvpn remoteaccess

Part 4 — Site-to-site VPN configuration on EdgeRouter
If you want a site-to-site tunnel, configure a separate OpenVPN client instance or adapt the existing one depending on your EdgeOS version and server requirements.

Step 1: Define the remote gateway

• Remote gateway IP: the public IP or DNS name of the remote site.

Step 2: Set the tunnel parameters

• Protocol: UDP/TCP as required by the server
• Port: 1194 common or a custom port
• Local network: your LAN on EdgeRouter side
• Remote network: the LAN on the remote site
• PFS, cipher, and TLS settings to match the server

Example CLI conceptual
set vpn openvpn site2site server ‘remote.openvpn.server’
set vpn openvpn site2site mode ‘site-to-site’
set vpn openvpn site2site dev-type ‘tun’
set vpn openvpn site2site port 1194
set vpn openvpn site2site protocol ‘udp’
set vpn openvpn site2site ca ‘/config/auth/openvpn/ca.crt’
set vpn openvpn site2site cert ‘/config/auth/openvpn/client.crt’
set vpn openvpn site2site key ‘/config/auth/openvpn/client.key’
set vpn openvpn site2site remote-subnet ‘10.1.0.0/24’
set vpn openvpn site2site local-subnet ‘192.168.1.0/24’
set vpn openvpn site2site tls-auth ‘/config/auth/openvpn/ta.key’
commit
save

Note: Some EdgeRouter versions consolidate site-to-site and remote-access under the same OpenVPN client block with multiple routes. Check your EdgeOS version specifics. India vpn browser guide 2025: best India vpn browser extensions, geo-unblocking, privacy tips, and fast servers

Section 5 — Routing, NAT, and firewall rules
Routing

• Ensure the EdgeRouter knows about the VPN subnets and where to route traffic back to your LAN.
• Add static routes if needed:
  Example: route 10.8.0.0/24 via vpn0
• For site-to-site, ensure both sides know how to reach the opposite LANs.

NAT

• Trust the VPN subnets as internal networks, not NATed to the internet if you want devices on the VPN to access the internet via their own VPN path or the remote network to access the internet through the EdgeRouter.
• Typical approach: Do not NAT traffic from VPN subnets to the internet if you want true site-to-site connectivity; NAT only internal traffic if needed.

Firewall

• OpenVPN interface should be allowed through the firewall:
  set firewall name WAN_LOCAL rule 10 action accept
  set firewall name WAN_LOCAL rule 10 destination port 1194
  set firewall name WAN_LOCAL rule 10 protocol udp
• Allow traffic from VPN networks to internal resources as needed:
  set firewall name VPN_ACCEPT rule 10 action accept
  set firewall name VPN_ACCEPT rule 10 source address ‘10.8.0.0/24’ // example
• Ensure you have rules that reflect your access policy remote users vs site-to-site traffic.

Section 6 — Testing and validation
Initial checks

• Verify OpenVPN client status:
  show vpn openvpn remoteaccess
• Look for a connected state and a valid IP address on the VPN interface.
• Check routes:
  show ip route
• Confirm VPN subnet routes exist and pointing to the VPN interface tun or similar.

Connectivity tests Cyberghost vpn location

• From a remote client, ping the EdgeRouter’s LAN devices e.g., 192.168.1.10.
• From the EdgeRouter, ping remote site devices e.g., 10.1.0.5 if site-to-site is configured.
• Test outbound internet traffic from a VPN-connected device if allowed by your setup.

Troubleshooting steps

• If you don’t see a VPN IP, double-check the server address, port, protocol, and credentials.
• If routes aren’t appearing, verify push routes on the OpenVPN server and ensure the EdgeRouter is using the right VPN instance.
• If traffic isn’t routing, check firewall rules and NAT settings. Ensure VPN traffic is allowed through WAN_LOCAL and VPN_ACCEPT rules.
• DNS resolution for VPN clients: consider configuring a DNS server that both sides can access or push DNS options from the server.

Section 7 — Maintenance and tips

• Regularly update EdgeRouter firmware to stay compatible with OpenVPN features and security patches.
• Keep certificate lifetimes in check; renew before they expire and rotate keys on both server and client as needed.
• Document your topology: list which networks are on VPN, which devices use remote access, and which pairs are connected via site-to-site.
• Back up your OpenVPN configuration and the EdgeRouter configuration files.
• Consider monitoring VPN uptime and traffic with simple alerting. You can set up syslog or a lightweight monitoring tool to observe VPN interface states.

Format tips and best practices

• Keep the OpenVPN config modular: separate remote access and site-to-site configurations if your EdgeRouter supports it, then test them independently.
• Use separate VPN pools for remote clients vs site-to-site tunnels to avoid IP conflicts.
• For remote access, set up client-specificOptions to assign fixed IPs to users if your OpenVPN server supports it.
• Document the exact server config used server IP, port, protocol, TLS parameters so you can replicate or troubleshoot quickly.

Security considerations

• Use strong TLS ciphers and client certificates. Avoid outdated ciphers and protocols.
• Limit VPN access to necessary subnets. Apply the principle of least privilege.
• Regularly rotate credentials and keys, especially if a device is lost or compromised.
• Consider enabling TLS-auth or TLS-crypt if your server supports it for an extra layer of protection.

Advanced tips Edge vpn for pc free download

• If you’re dealing with dynamic IPs on the OpenVPN server, consider a dynamic DNS setup for the server side so your EdgeRouter can reliably reconnect.
• For large networks, create multiple OpenVPN client instances to segment traffic more cleanly and simplify routing.
• If you’re experiencing instability, test with TCP vs UDP to see if one protocol is more stable in your environment.

FAQ Section

Frequently Asked Questions

Do I need a certificate for each remote client?

Yes, for best security and management, individual client certificates are recommended, especially for remote access setups. If you’re using a server that supports a common pool or user-based auth, you can use per-user certificates or credentials as appropriate.

Can EdgeRouter run multiple OpenVPN clients at the same time?

Yes, EdgeRouter supports multiple OpenVPN client configurations, but you’ll need to assign unique interface names or instances for each and carefully manage routing and firewall rules to avoid conflicts.

How do I verify that traffic is flowing through the VPN tunnel?

Check the VPN status on the EdgeRouter, verify routes exist for the VPN subnet, and perform end-to-end pings from a remote device to a device on the opposite network. Use traceroute to see the path.

What’s the difference between remote access and site-to-site in OpenVPN?

Remote access is for individual users or devices to connect to a central VPN server. Site-to-site connects two networks so devices on either side can talk to each other as if on the same LAN.

What about NAT on VPN traffic?

Typically, you don’t NAT traffic between two internal networks unless you have a specific reason. For remote access, you may NAT traffic from VPN clients to your LAN depending on your network design.

How do I handle DNS for VPN clients?

You can push a DNS server to VPN clients from the server, or configure the EdgeRouter to use a DNS server that’s reachable from the VPN. Some setups route VPN clients to your local DNS or a public DNS depending on your policy.

How often should I rotate certificates and keys?

Rotate certificates every 1–2 years and keys every 2–3 years, or sooner if you suspect a compromise. Always have a backup plan and test rotation in a controlled manner.

Can I use a dynamic IP on the OpenVPN server?

Yes, but you’ll want a stable connection mechanism for the EdgeRouter to reconnect automatically. Consider dynamic DNS on the server side or a reliable hostname in your server config.

What if OpenVPN isn’t starting on EdgeRouter?

Double-check the file paths for certificates, correct server address and port, and ensure no port conflicts. Review system logs for OpenVPN-related errors and fix any missing dependencies or misconfigurations. Browsec vpn for firefox

Prerequisites and planning

• A working OpenVPN server you can connect to wireless or wired clients, or a remote office. Know:
  • Server address and port default UDP 1194, but it could be TCP 443 or another port
  • VPN protocol UDP is usually faster. TCP can be more reliable through restrictive networks
  • Whether TLS-auth ta.key is used
  • CA certificate, client certificate, and client key and potentially a shared secret
• EdgeRouter model and OS version EdgeOS 1.x/2.x with administrative access
• Basic networking details:
  • What VPN subnets will be used for example, 10.8.0.0/24
  • Whether you’ll do full-tunnel or split-tunnel routing
  • Firewall policies to allow VPN traffic
• If you’re doing site-to-site, ensure the other side allows a VPN client connection with a matching profile and subnets

OpenVPN client on EdgeRouter: GUI method recommended for most users

1. Prepare the server-side files

• Obtain CA certificate, client certificate, and client key from the OpenVPN server
• If TLS-auth is used, have the ta.key as well
• If you’re using an inline .ovpn file, you can extract the pieces and paste them into EdgeRouter fields

2. Log into EdgeRouter’s GUI

• Open a browser and connect to your EdgeRouter’s management IP
• Navigate to VPN > OpenVPN > Client

3. Create a new OpenVPN client profile

• Name the client e.g., OfficeVPN or RemoteAccess
• Server address: enter the VPN server hostname or IP
• Server port: 1194 or your chosen port
• Protocol: UDP or TCP if required by your server
• VPN type: Client mode
• Authentication: TLS if your server uses TLS
• Encryption: choose a cipher your server supports AES-256-CBC is common. AES-256-GCM may be supported on newer devices
• TLS-auth: enable and provide ta.key if you’re using TLS authentication
• CA certificate: paste or import the CA certificate
• Client certificate and key: paste/import the client certificate and client key
• Optional: TLS version and extra options your server requires
• Device: EdgeRouter’s internal tun interface usually tun0 or a similar device is created automatically

4. Configure IP addressing and routing

• The EdgeRouter will assign an internal VPN IP e.g., 10.8.0.2 once the tunnel comes up
• Set a static route or policy-based routing if you want traffic to or from specific subnets to go through the VPN
• If you need full tunnel, set the default route to the VPN interface 0.0.0.0/0 via tun0
• If you want split tunneling, add specific routes for VPN resources and leave the rest to go through your normal WAN

5. Firewall policies

• Allow traffic from the VPN interface to your internal networks and back
• If you want Internet-bound VPN traffic, ensure NAT and firewall rules allow it
• Add a rule to drop any malformed VPN traffic and monitor logs for anomalies

6. Save and apply

• Click Save/Apply, then test the connection
• Check the VPN status LED or the GUI status indicator to confirm the tunnel is up
• Test connectivity by pinging a host behind the VPN or the VPN server

7. Automatic startup

• EdgeRouter normally starts VPN clients on boot if configured. confirm the service is enabled so the tunnel comes up after a reboot

Notes: Edge free download for windows 7

• If you only want to connect to certain resources over VPN split tunneling, keep the default route intact and add specific static routes for the VPN subnet to your target networks
• For multi-site setups, mirror the server config on each side with appropriate subnets and route rules

OpenVPN client on EdgeRouter: CLI method advanced

If you prefer the command-line or need to automate deployment, you can configure the OpenVPN client using EdgeOS CLI. The exact commands vary a bit by EdgeOS version, but the general steps are:

1. Access the CLI

• SSH into your EdgeRouter or use the local console
• Enter configuration mode: configure

2. Create a VPN client profile

• Define a name for this OpenVPN client for example, OfficeVPN
• Import or paste the certificate data CA, client cert, client key
• Provide the server address, port, protocol, and any TLS-auth key

3. Attach the VPN interface and set routing

• Create or configure the tun interface for example, tun0
• Set the remote endpoint server address, the port, and the protocol
• Configure the local and remote VPN subnets
• Add static routes or policy-based routing rules to control which traffic goes through the VPN

4. Firewall and NAT

• Open the necessary firewall zones or rules to permit VPN traffic
• Ensure NAT/masquerade is set if you’re sending VPN traffic to the Internet

5. Commit and save

• Run commit to apply the changes
• Run save to persist across reboots
• Exit and verify the VPN connection status

Important note: The CLI syntax can differ significantly between EdgeOS versions. If you’re on EdgeOS 2.x, some commands may use different sections or naming conventions. Always refer to your device’s help pages help.ui.com or run local help commands on the CLI to verify syntax.

How to choose between OpenVPN and WireGuard on EdgeRouter

• OpenVPN is widely compatible and works across many devices, with strong security when configured properly
• WireGuard is faster on most devices and simpler to configure, but it may require different server support and firewall tweaks
• If your server supports both, you can start with OpenVPN to ensure broad compatibility and then explore WireGuard as a performance improvement option
• For remote work with legacy clients, OpenVPN remains the safer default choice

Performance considerations and tips

• CPU power matters: VPN encryption is CPU-intensive. On EdgeRouter devices with multiple cores, you’ll see better VPN throughput. Expect lower throughput on older devices when using OpenVPN
• Protocol choice: UDP generally provides lower latency and better throughput than TCP
• Cipher and TLS settings: AES-256-CBC is common and compatible. AES-256-GCM can be faster if supported on both sides
• TLS-auth and HMAC: Enabling TLS-auth ta.key adds security and can help with stability in some environments
• Compression: Disabling data compression comp-lzo off is typically recommended to avoid known OpenVPN compression weaknesses
• Split tunneling: If you don’t need all traffic to go through the VPN, use static routes to limit VPN usage to specific subnets
• DNS handling: Use VPN-provided DNS or push a DNS server inside the VPN. this reduces the risk of DNS leaks
• Monitoring: Enable logging for VPN events and regularly review the VPN connection uptime, packet loss, and latency

Security best practices

• Keep server certificates and keys secure. rotate certificates periodically
• Use TLS-auth if your server supports it, to protect against some common TLS attacks
• Prefer strong ciphers and latest OpenVPN versions
• Disable vulnerable features like outdated compression and stay current with EdgeRouter OS updates
• If possible, use certificate-based authentication rather than username/password combinations

Troubleshooting common issues

• VPN won’t connect
  • Double-check server address, port, and protocol
  • Confirm server accepts client authentication and that the client cert matches the server
  • Check firewall rules allowing VPN traffic in and out
• TLS or certificate errors
  • Make sure the CA cert, client cert, and client key are correct and match the server
  • Confirm you’re using the correct TLS-auth key if required
• DNS leaks
  • Ensure your VPN pushes a DNS server and that your DNS settings on the EdgeRouter point to it
• Traffic not routing through VPN split-tunnel issue
  • Inspect static routes and policy-based routing rules
  • Ensure there are no conflicting default routes that override the VPN
• Performance is slow
  • Test with different cipher settings
  • Check for CPU spikes and adjust VPN settings accordingly
  • Consider upgrading EdgeRouter hardware if you consistently hit throughput limits

Testing and verification

• Confirm tunnel status in the GUI or CLI and verify tun0 or the appropriate interface is up
• Check the VPN’s assigned IP address on the EdgeRouter and on a connected client
• Ping internal VPN resources servers inside the VPN network
• Run traceroute to verify that traffic takes the VPN path when intended
• If you’re doing site-to-site, verify connectivity across both networks subnets should reach each other

Real-world tips and best practices

• Start with a simple remote access setup to verify connectivity before attempting a full site-to-site bridge
• Keep a documented backup of your original EdgeRouter configuration before making changes
• If your ISP blocks VPN traffic, try a different port or protocol and consider TCP as a fallback
• Maintain a test environment to validate changes before rolling them out to production
• Use a reputable VPN provider for personal or small-business needs, but for fully in-house control, host your own OpenVPN server and limit exposure
