Part I: Setting up OpenVPN on EdgeRouter X remote access
Overview
– OpenVPN server on EdgeRouter X provides secure remote access for individual clients and can support multiple users with unique credentials.
– You’ll create a VPN server, configure encryption settings, generate or upload client certificates or use username/password if supported, set client IP pools, and ensure routing to your LAN.
Step-by-step GUI-based approach
1 Log in to EdgeRouter X UI and navigate to VPN settings.
2 Enable OpenVPN server and choose server mode remote access and the protocol UDP is common for VPNs.
3 Set a server IP pool for VPN clients for example, 10.8.0.0/24 and pick an appropriate subnet that doesn’t collide with your LAN.
4 Configure TLS/CA settings:
– Create or import a CA certificate and a server certificate
– Set up TLS authentication if supported tls-auth or tls-crypt
5 Create user accounts for remote access or upload client certificates. Assign each user a unique username and password or a client certificate.
6 Define client routing:
– Route all traffic through the VPN redirect-gateway
– Or route only specific subnets split tunneling
7 Firewall rules:
– Allow VPN traffic on the chosen OpenVPN port default 1194 UDP
– Permit VPN clients to reach the LAN LAN access
8 NAT and firewall:
– Ensure NAT is enabled so VPN clients can access the internet via the EdgeRouter X public IP.
– Add rules to drop traffic from VPN clients to unneeded destinations if necessary defensive default-deny
9 Save and apply, then export client profiles if using certificates or share login credentials with remote users.
10 Test with a remote client:
– Install an OpenVPN client, import the profile or enter credentials, connect, and verify access to LAN resources and the internet.
Step-by-step CLI-based approach, for advanced users
– Connect via SSH, enter configuration mode, and follow the same logical steps as above but with EdgeOS CLI commands, focusing on:
– VPN OpenVPN server enablement
– Server subnet and tunnel network
– TLS and CA configuration
– Client authentication setup
– Firewall and NAT rules
– If you’re not sure of the exact CLI syntax for your EdgeOS version, consult the EdgeRouter X official docs or use the GUI, which is less error-prone for beginners.

– Consider enabling TLS authentication tls-auth if supported.
– Implement strong client authentication certificates preferred and keep credentials confidential.
– Use a separate VPN VLAN or dedicated firewall zones to segment VPN traffic from your main LAN.
– Regularly update EdgeOS to the latest stable version to patch vulnerabilities.
Part II: Setting up WireGuard on EdgeRouter X remote access and faster VPN
– WireGuard is favored for speed and simpler configuration where supported. If your EdgeOS version includes WireGuard, you can set up a lightweight VPN server for remote clients or even a site-to-site link.
1 Open the EdgeRouter X UI and navigate to VPN or WireGuard sections depending on your firmware.
2 Enable WireGuard server and specify a private key for the server.
3 Create peer configurations for each client:
– Generate a public/private key pair for the client
– Assign a unique IP from a dedicated WireGuard subnet e.g., 10.200.200.0/24
– Share the client public key and allowed IPs with the user
4 Define allowed IPs and routes to access LAN resources or the internet through the VPN.
5 Firewall rules:
– Allow WireGuard port default 51820 UDP from the WAN interface or as needed
– Permit traffic from the WireGuard subnet to LAN and, if desired, to the internet
6 Test the connection by connecting a client and verifying LAN access and internet reachability.
Step-by-step CLI-based approach
– Use the CLI to generate server keys, configure the server interface, add peers, and set firewall rules. The exact commands will depend on EdgeOS version, but the flow is:
– Create a WireGuard interface for the server
– Add peer configurations with public keys and allowed IPs
– Configure NAT and routing for VPN traffic
– Open the UDP port in the WAN firewall
– If you’re new to WireGuard on EdgeRouter X, start with GUI and reference EdgeOS docs to fill in the exact CLI syntax.
Security tips for WireGuard
– Use a strong private key for the server and keep client keys secure.

– Consider combining WireGuard with a VPN user policy that restricts access times or destinations.
– Monitor VPN traffic with EdgeRouter’s logging features and set alerts for abnormal activity.
Part III: Site-to-site VPN EdgeRouter X
– A site-to-site VPN connects two networks securely over the internet, typically used to join a home/branch office network with a remote network.
– OpenVPN is often used for site-to-site due to its mature feature set and compatibility, whereas WireGuard can offer speed benefits when both sites support it.
Steps to set up a basic site-to-site VPN
1 Decide which side will be the VPN server and which will be the client or set up a mutual peering as needed.
2 On the EdgeRouter X at the primary site, configure a VPN server OpenVPN or WireGuard with a fixed public IP or dynamic DNS as the endpoint.
3 On the remote site EdgeRouter X, configure the VPN client with the matching server settings and the remote peer’s public key.
4 Create 1:1 subnet routing rules and static routes:
– Add static routes so devices on the remote site can reach your local LAN behind EdgeRouter X
– Add corresponding routes on the primary site for the other network
5 Firewall and NAT:
– Allow VPN traffic through WAN firewall
– Ensure NAT is configured to translate traffic from VPN sites to the internet
6 Test end-to-end:
– Ping devices across sites, test file transfers, test access to remote resources, and verify latency.
Site-to-site tips
– Use distinct subnets for each side to prevent IP conflicts and simplify routing.
– Keep an eye on MTU to avoid fragmentation. set MTU values accordingly for VPN tunnels.
– Document the site-to-site topology and keys/certificates. rotate keys on a schedule.
Network hygiene and performance considerations
– DNS and DNS leak protection:
– Use a trusted DNS provider behind the VPN e.g., Cloudflare, Quad9
– Consider forcing VPN clients to use the VPN DNS to prevent leaks
– Split-tunneling vs full-tunneling:
– Decide whether VPN clients should route all traffic through the VPN or only traffic bound for the LAN
– Split tunneling can improve performance for remote users but may reduce privacy
– NAT and firewall basics:
– Ensure VPN clients can reach LAN resources without exposing the entire network
– Apply a minimal, strict firewall policy to VPN interfaces
– Performance tuning:
– Disable unnecessary services on EdgeRouter X to reduce CPU load
– Tune MTU and fragmentation settings if you experience packet loss or instability
