What is EdgeRouter X and why run a VPN server there?
EdgeRouter X is a compact, affordable router from Ubiquiti that runs EdgeOS, a Linux-based router operating system. It’s designed to handle small to medium home or office networks with solid routing performance, advanced firewall features, and customizable VPN options. Running a VPN server directly on EdgeRouter X gives you:
– Centralized remote access to your home or office network without relying on a third-party VPN provider for your primary connection.
– The ability to split traffic or route all traffic through your home network depending on your needs.
– A single point of control for multiple devices connecting remotely, which can improve security hygiene certificates, firewall rules, and DNS controls all in one place.
That said, EdgeRouter X has limited CPU headroom compared to larger enterprise devices. If you expect dozens of concurrent VPN clients or high-throughput requirements, WireGuard generally offers better performance, while OpenVPN provides broad compatibility with many clients.
Prerequisites and planning
Before you start, gather these basics:
– A working EdgeRouter X with EdgeOS firmware update to the latest stable release if possible.
– A stable internet connection with a public IP or a dynamic DNS setup if your public IP changes.
– A LAN-aware network plan: decide the VPN network segment for example, 10.8.0.0/24 for OpenVPN, or 10.9.0.0/24 for WireGuard.
– A device you’ll use to generate client certificates/keys for OpenVPN or access key pairs for WireGuard.
– A plan for firewall rules and port exposure: the VPN server will need a UDP/TCP port open on the WAN interface depending on protocol.
Security baseline you should aim for:
– Use strong server authentication credentials certificates for OpenVPN or long-lived keys for WireGuard.
– Enable firewall rules to restrict VPN access to known management IPs if possible, or at least limit which ports are exposed.
– Consider disabling WAN SSH access if you don’t need it, and enable SSH with key-based access only.
– Use a reliable DNS server for clients to avoid DNS leaks. consider pushing private/internal DNS servers to clients.
OpenVPN server on EdgeRouter X: setup steps
OpenVPN is widely compatible with many clients and platforms. On EdgeRouter X, you typically enable the OpenVPN server via the EdgeOS GUI or CLI and provide a tunnel network.
What you’ll do:
– Create a VPN network e.g., 10.8.0.0/24 and a tun interface for OpenVPN.
– Configure authentication with certificates or username/password depending on your security preference.
– Set the VPN server to listen on a chosen port commonly UDP 1194 and protocol UDP for better performance, TCP if you need reliability in lossy networks.
– Push routes to clients so they can reach your LAN behind EdgeRouter X.
– Add NAT rules if you want VPN clients to access the internet through your home network.
High-level CLI example conceptual, not exact syntax:
– set interfaces openvpn tun0 mode server
– set interfaces openvpn tun0 server net 10.8.0.0/24
– set interfaces openvpn tun0 server protocol udp
– set interfaces openvpn tun0 server port 1194
– set service vpn-server openvpn disable
– set firewall name VPN-IN rule 10 action accept
– set firewall name VPN-IN rule 10 destination address 10.8.0.0/24
– set nat source rule 100 outbound-interface eth0
– set nat source rule 100 translation address masquerade
Client configuration essentials:
– A client certificate and key for each device or username/password if using TLS with static keys
– A client config file .ovpn containing: client, dev tun, remote
Tips:
– If you’re behind CGNAT or dynamic IPs, pair OpenVPN with a dynamic DNS host to avoid frequent client config updates.
– Use TLS-auth or TLS-crypt keys to harden the OpenVPN handshake against certain attacks.
– Consider enabling a DNS server push or a DNS forwarder to prevent DNS leaks.
WireGuard on EdgeRouter X: setup steps
WireGuard is known for performance. If you’re seeking lower latency and higher throughput on EdgeRouter X, WireGuard is often the better option, provided your clients support it.
– Install or enable WireGuard support in EdgeOS depending on firmware version.
– Create a WireGuard interface on EdgeRouter X and assign it an internal VPN address e.g., 10.9.0.1/24.
– Generate a private/public key pair for the EdgeRouter and add peers for each client with their public keys and allowed IPs.
– Expose the WireGuard port default 51820 UDP on the WAN interface.
– Add appropriate firewall rules to allow WireGuard traffic and to protect the LAN behind the EdgeRouter.
– Export or configure the client config for each device, including the EdgeRouter’s public key and the peer’s allowed IPs.
High-level outline conceptual:
– set interfaces wireguard wg0 address 10.9.0.1/24
– set interfaces wireguard wg0 private-key
– set service wireguard listen-port 51820
– set interfaces wireguard wg0 peer
– set firewall name WG-IN rule 10 action accept
– set firewall name WG-IN rule 10 destination port 51820
– commit and save
Client setup basics:
– For Windows/macOS/iOS/Android, import or paste the client config that includes the router’s public key, endpoint your public IP or DDNS, and the shared allowed IPs 10.9.0.2/32 for a single client, or a broader range for multiple clients.
– Use the WireGuard app on each client to enable the tunnel and test connectivity to your LAN resources.
Why choose WireGuard over OpenVPN here?
– Higher throughput and lower CPU load on EdgeRouter X’s hardware.
– Simpler key management: a small set of keys per client vs large certificate infrastructure.
– Potentially easier to troubleshoot with fewer moving parts, though OpenVPN has broader compatibility.
Firewall, NAT, and routing considerations
– Firewall rules: Ensure the VPN service is accessible from the WAN interface, but restrict access to only the required ports 1194 UDP for OpenVPN, 51820 UDP for WireGuard. Keep your LAN protected by a default deny policy that still allows VPN subnets to reach local resources you want accessible.
– NAT: If you want VPN clients to access the internet through your home network, configure NAT on the EdgeRouter X so that VPN clients’ traffic is masqueraded when leaving the WAN interface.
– Routing: For OpenVPN, push the correct routes to clients so they can reach your internal subnets for example, 192.168.1.0/24. For WireGuard, set AllowedIPs on the client peers to reflect which internal networks should be reachable via the VPN.
– DNS handling: Decide whether VPN clients should use your home DNS to resolve internal hostnames or external DNS servers. If you push DNS from the server, ensure you’re not leaking DNS queries to third parties.
Tips to keep it simple:
– Start with remote access only a single client to validate connectivity, then scale to multiple clients.
– Use a dedicated VPN subnet that doesn’t collide with your LAN addressing e.g., 10.8.0.0/24 for OpenVPN, 10.9.0.0/24 for WireGuard.
– If you want to access local network resources by name, set up DNS forwarding or an internal DNS server to resolve those hostnames.
Client configuration and testing
Windows/macOS:
– OpenVPN clients: import the .ovpn file. connect using the VPN profile. verify you can ping internal hosts e.g., 192.168.1.10 and access internal services.
– WireGuard clients: import the generated .conf file. activate the tunnel and test connectivity to LAN resources.
iOS/Android:
– OpenVPN Connect or WireGuard app: import the config or key material. enable the tunnel and test.
Testing steps:
– Connect from an external network cellular data or a different Wi-Fi network.
– Verify “full tunnel” behavior vs “split tunnel” behavior you configured traffic to VPN-only resources vs all traffic going through the VPN.
– Check that DNS queries don’t leak by visiting a site that shows your IP and verifying it shows your home IP instead of the mobile IP.
– Verify that your internal hosts are reachable by hostname and IP.
Performance considerations:
– WireGuard on EdgeRouter X generally provides better throughput than OpenVPN due to its lean design. Expect more consistent performance on typical home internet connections.
– OpenVPN can perform well, but CPU-limited devices will show more variance, especially when using high encryption levels or pushing large client sets.
– If you’re using a slower uplink, consider tuning MTU settings and avoiding unnecessary tunnel overhead e.g., avoid double NAT beyond what you need.
Security hardening tips
– Use certificate-based authentication where possible OpenVPN and keep your CA and server certificates rotated on a schedule.
– Prefer TLS-auth or TLS-crypt keys to mitigate certain TLS attacks.
– Disable remote admin access on WAN when you don’t need it. Use a VPN for administration if remote changes are necessary.
– Regularly monitor logs VPN login attempts and tunnel status and set up alerting if possible.
Troubleshooting common issues
– VPN connection fails to establish:
– Check that the correct port is forwarded on your firewall/NAT and not blocked by an upstream device.
– Confirm that the server’s public IP or DDNS hostname is reachable from the client’s location.
– Verify that the VPN credentials certificates/keys match between client and server.
– DNS leaks:
– Ensure the VPN server provides DNS settings to clients or configure a DNS server IP in the client configuration.
– Test DNS leakage with online tools to confirm resolution happens inside the VPN tunnel.
– Slow VPN speeds:
– Check CPU usage on EdgeRouter X during VPN activity. high usage indicates CPU bottleneck.
– For OpenVPN, experiment with UDP vs TCP settings and consider reducing encryption overhead if feasible keep security in mind.
– If possible, switch to WireGuard for improved performance.
Use-cases and scenarios
– Remote access for a few devices: OpenVPN or WireGuard configured for 2–5 clients is a straightforward solution, with moderate performance and robust compatibility.
– Remote office access: WireGuard tends to be better for higher throughput and easier multi-client management, especially when you’re connecting multiple remote devices.
– Privacy-conscious home users: If you want to ensure all traffic from remote devices goes through your home network, enable full-tunnel routing and use DNS controls to maintain privacy within your LAN.
Advanced tips
– Dynamic DNS: If your public IP changes, set up a dynamic DNS service e.g., DuckDNS, No-IP to ensure clients can always reach your VPN server without updating config files.
– Split tunneling: If you only want specific traffic to go through the VPN, configure split tunneling by adjusting the routes and AllowedIPs accordingly in your WireGuard or OpenVPN client configurations.
– Client certificate rotation: Periodically rotate certificates/keys and revoke older ones. Keep a current revocation list to avoid access by old clients.
– Monitoring and logging: Enable VPN login attempt logging and review regularly to detect unauthorized access attempts.

# Can I run both OpenVPN and WireGuard on the same EdgeRouter X?
It’s possible to run both, but it adds complexity. If you’re just starting, pick one protocol that best fits your needs and scale later if necessary.
# How do I access internal resources remotely?
Configure appropriate VPN routes that include your internal subnets e.g., 192.168.1.0/24 and ensure your firewall rules allow traffic from the VPN subnet to the internal network. For name resolution, push internal DNS information to clients or run an internal DNS server.
# How do I set up port forwarding for the VPN service?
In EdgeRouter X, you’ll forward the VPN port 1194 UDP for OpenVPN or 51820 UDP for WireGuard from the WAN to the EdgeRouter’s VPN interface or tun/wg0 as appropriate. Ensure firewall rules permit this traffic, and test from an external network.
# How do I test VPN connectivity from a client?
Install the client software, import the config, and connect. Then ping internal hosts, test access to internal services, check for DNS resolution inside the VPN tunnel, and verify your external IP address shows your home network when browsing non-local sites.
# How can I improve VPN performance on EdgeRouter X?
Use WireGuard where possible for higher throughput and lower CPU usage. If you’re using OpenVPN, optimize MTU settings and reduce encryption overhead, while still maintaining strong security. Ensure the EdgeRouter X firmware is up-to-date and limit VPN traffic to essential devices if needed.
# What security practices should I follow for EdgeRouter VPN?
Use certificate-based authentication or strong keys, enable TLS-auth or TLS-crypt if OpenVPN, limit WAN exposure, disable unnecessary remote admin access, and regularly review logs for suspicious activity. Consider DNS controls and regular key rotation.
# Can I use a VPN server on EdgeRouter X with a dynamic IP?
Yes, but you’ll want a dynamic DNS service to ensure clients can always reach your server using a stable hostname. This avoids needing to update client configurations whenever your public IP changes.
# How do I back up and restore EdgeRouter X VPN configurations?
