Site-to-site VPN: connecting two networks securely

Site-to-site VPNs extend your trusted network across the internet to another location another ER-X or a different VPN-capable router. Here’s a practical outline:

1. Decide endpoints and networks

• Your primary site LAN: 192.168.1.0/24
• Remote site LAN: 192.168.2.0/24
• Public internet endpoints static IPs recommended.

2. Choose the protocol

• IPsec is a common choice for site-to-site due to compatibility and stability.
• OpenVPN can be used if you have devices that require it on both ends.

3. Configure both ends in sync

• Ensure matching subnet definitions, encryption settings, and peer authentication methods.
• Configure routing so traffic destined for the remote subnet uses the VPN tunnel.

4. Firewall and NAT

• Permit VPN traffic on both sides and ensure internal routing rules don’t block remote networks.
• If you have local NAT, adjust rules to avoid double NAT scenarios for site-to-site traffic.

5. Verification

• From a device on one site, ping devices on the other site, or access shared services across the tunnel.
• Confirm that traffic is encrypted by testing with a network monitor or verifying VPN logs.

Tips for site-to-site success:

• Use stable public IPs or a reliable dynamic DNS solution if you don’t have static IPs.
• Document the exact tunnel configuration so changes on either side stay aligned.
• Periodically test the tunnel latency and throughput to catch drift or misconfigurations early.

DNS, NAT, and firewall best practices for VPN on ER-X

• Use VPN-specific DNS settings to avoid DNS leaks. Push or configure a private DNS resolver through the VPN for remote clients.
• Keep firewall rules minimal but effective. Start with a default deny posture and add explicit allows for VPN traffic and necessary services.
• Consider separating VPN clients from the LAN with firewall zones or groups to prevent lateral movement in case of a compromised device.
• For site-to-site, disable unnecessary services on router interfaces exposed to the internet to reduce attack surface.
• Monitor VPN activity with logs and alerts. EdgeOS logs can help you recognize authentication failures or unusual traffic patterns.

Performance considerations and optimization tips

• Encryption overhead matters: OpenVPN uses more CPU power than IPsec or WireGuard, so on the ER-X you may see lower throughput when using OpenVPN with heavy encryption.
• Keep MTU in check: VPN tunnels add headers. if you notice fragmentation or slow connections, try lowering MTU by a small amount e.g., from 1500 to 1400 and test.
• Prioritize VPN traffic if needed: Use QoS rules to allocate bandwidth for VPN subnets or to prioritize sensitive applications.
• Use stable internet connections: If your primary link fluctuates, VPN stability will reflect that. A stable ISP and clean jitter helps VPN performance.
• Regular maintenance: Clear stale routes, review firewall rules, and prune old VPN users to keep the system lean.

Troubleshooting common VPN issues on EdgeRouter X

• VPN clients can’t connect: Check that the correct port is open UDP 1194 for OpenVPN by default, confirm server-side credentials, and verify firewall rules aren’t blocking traffic.
• Clients connect but can’t access LAN devices: Review firewall rules, ensure proper routing, and confirm that client-to-client or remote-network access is permitted as configured.
• DNS resolution fails over VPN: Ensure the VPN server pushes DNS settings to clients and that the DNS server is reachable via the VPN tunnel.
• Slow VPN performance: Test with different encryption settings, verify CPU load on the ER-X, and consider alternative protocols like IPsec or WireGuard if supported.
• Tunnel intermittency: Check for MTU issues, NAT-T compatibility, and keep both ends’ firmware up to date.

Monitoring, maintenance, and security hygiene

• Regular firmware updates: EdgeOS improvements often include VPN fixes and performance enhancements.
• Access control: Review user permissions periodically. remove old accounts and enforce strong passwords or certificates.
• Backups: Maintain a routine backup of the EdgeRouter X configuration after any significant VPN change.
• Logs and alerts: Set up basic monitoring for VPN connection attempts and unusual traffic patterns.
• Documentation: Keep a living document of your VPN topology, including IP ranges, remote endpoints, and credentials rotated securely.
