- Create Phase 2 proposals for the traffic subnets that will traverse the tunnel
- Configure peer endpoints with public IPs or dynamic DNS
- Set up firewall rules to permit IPsec traffic ESP, Ah, IKE
- Ensure NAT traversal is configured if behind NAT
Remote access with IPsec
- Some OPNSense setups use IPsec for remote workers via IKEv2 or IKEv1 with certificates or EAP, depending on compatibility
Practical tips
- Use strong pre-shared keys or certificates for authentication
- Enable PFS Perfect Forward Secrecy for added security
- Monitor tunnel status and use keepalive or dead-peer-detection

Configuring a site-to-site VPN with multiple branches The Ultimate Guide Best VPN For Your UGREEN NAS In 2026: Fast, Safe, and Easy to Use

Plan subnets and routing
- Map each branch’s internal network e.g., 192.168.2.0/24, 192.168.3.0/24 and the central network e.g., 192.168.1.0/24
- Decide on a hub-and-spoke or full mesh topology
Setup steps example with IPsec
- Create a tunnel for each site with unique identifiers
- Define IKE/IPsec proposals that support all sites
- Update firewall rules on each site to allow traffic across the VPN
- Configure static routes or dynamic routing OSPF/BGP if needed for automatic route propagation
Performance considerations
- Bandwidth is the bottleneck more often than CPU; scale hardware or add WAN links if you need more throughput
- Use compression carefully; modern VPNs may not benefit from compression and can cause issues with certain traffic
Practical tips
- Test each tunnel individually before enabling full mesh
- Use consistent subnet masks across sites to simplify routing
- Keep firmware and OPNSense plugins up to date to maintain security

Client access: remote workers and BYOD

Remote access options
