What you should know before you start
Before you dive in, a few real-world facts to set expectations:
– EdgeRouter X runs EdgeOS, which gives you CLI-like control via a Web UI or SSH. You’ll be editing interfaces, VPN instances, firewall rules, and routing policies.
– VPN performance on EdgeRouter X is strongly influenced by your internet speed, your VPN protocol, and the encryption settings you choose. OpenVPN tends to be more CPU-intensive than IPsec on many small routers, which can cut throughput noticeably if you’ve got a fast ISP.
– OpenVPN is widely supported by VPN providers and supports both client and server modes. IPsec often paired with L2TP is another solid option, sometimes easier to tune for performance with certain providers.
– For home networks, most folks end up with one of two workflows: a Use OpenVPN as a client on the EdgeRouter X to route all traffic through the VPN, or b Run OpenVPN or IPsec on a dedicated device inside the network or on a connected server and route traffic there. A site-to-site VPN site A to site B is also possible if you need a secure link between two locations.
– If you want WireGuard, note that native support on EdgeRouter X is not always available in all EdgeOS versions. You can run WireGuard on a separate device behind the router or upgrade to a newer router that ships with WireGuard support.
VPN options on Ubiquiti edgerouter x
– OpenVPN client: The most common, widely documented choice. It’s compatible with most major VPN providers and supports per-user certificates. It’s also straightforward to configure if you have a config file .ovpn or the necessary CA/cert/key materials.
– OpenVPN server: Useful if you want remote access to your home network without exposing individual devices. It requires certificate management and careful firewall rules to keep things secure.
– IPsec/L2TP: A robust alternative that’s often easier on the CPU than OpenVPN. It’s commonly used for site-to-site tunnels or remote access where the VPN provider gives you a ready-made setup.
– Site-to-site VPN: Connect EdgeRouter X at home to a partner router at another location. This is great for small offices or multi-location home labs.
– WireGuard: Increasingly popular for its simplicity and speed. Native support on EdgeRouter X depends on EdgeOS version. if not available, you can run WireGuard on a connected device or use a VPN service that provides a compatible setup and configure through the router.
Tips:
– Start with a clear goal: remote access for yourself, all traffic through VPN, or a site-to-site tunnel. That will determine your best protocol and topology.
– If your main goal is privacy for all devices, OpenVPN client mode is reliable and well-documented. If you need maximum speed and have compatible hardware, IPsec might offer better throughput.
– Always secure VPN credentials and certificates, and limit VPN access with firewall rules so only legitimate users can connect.
OpenVPN client on EdgeRouter X step-by-step
The OpenVPN client path is a favorite for many users because it’s widely supported and works well with most providers.
What you’ll need:
– A valid OpenVPN config .ovpn file from your VPN provider, or separate CA certificate, client certificate, and private key.
– Access to the EdgeRouter X Web UI or SSH.
High-level steps:
– Prepare your OpenVPN materials: if you have a single .ovpn file, you’ll extract the CA, cert, and key portions and prepare them for EdgeOS. If you have just a config, you’ll translate it into EdgeOS-compatible parts remote server, port, protocol, ca cert, client cert, key, and TLS-auth if used.
– Create an OpenVPN client instance and assign a local VPN interface vtun or tun in EdgeOS.
– Configure the OpenVPN client with the server address, port, and authentication data.
– Push the VPN’s virtual interface into your routing table so that traffic from your LAN goes through the VPN tunnel.
– Integrate with firewall rules to ensure VPN-protected traffic is allowed and to block leaks if the VPN goes down kill switch.
Example outline non-executable, conceptual:
– set interfaces openvpn vtun0 mode client
– set interfaces openvpn vtun0 local-address 10.8.0.2
– set interfaces openvpn vtun0 remote-address 10.8.0.1
– set interfaces openvpn vtun0 protocol udp
– set interfaces openvpn vtun0 port 1194
– set interfaces openvpn vtun0 dev tun
– set interfaces openvpn vtun0 server-ca-cert /config/ssl/ca.crt
– set interfaces openvpn vtun0 client-cert /config/ssl/client.crt
– set interfaces openvpn vtun0 client-key /config/ssl/client.key
– set interfaces vtun0 description “OpenVPN client”
– set protocols static route 0.0.0.0/0 next-hop-interface vtun0
– set firewall name VPN-LOCAL-INPUT default-action drop
– set firewall name VPN-LOCAL-INPUT rule 10 action accept source address 10.8.0.0/24
– commit and save
Notes:
– If your VPN provider supplies an all-in-one .ovpn file, you’ll often place that content into the EdgeRouter’s OpenVPN client and roll with the defaults. If there are TLS-auth or certificate chains, include those pieces in the proper EdgeOS paths.
– UDP generally gives better latency and throughput than TCP for VPNs, but your provider’s server config may dictate otherwise.
Performance tips:
– Use UDP as the transport protocol where possible to minimize overhead.
– If your EdgeRouter X is older or under heavy load, expect VPN throughput to be lower than the router’s raw routing performance. An OpenVPN client on a modest CPU may see noticeable slowdowns at higher WAN speeds.
– Consider splitting traffic: route only sensitive devices or traffic through the VPN, keep other devices on your local ISP path for speed. This can be done with policy-based routing PBR rules in EdgeOS.
Common issues and quick fixes:
– VPN client refuses to connect: verify CA and client certs, ensure time synchronization NTP, and check server address/port and firewall rules.
– DNS leaks: push DNS servers to the VPN or configure a dedicated DNS over VPN, not your local ISP’s DNS.
– Kill switch not working: ensure the default route via the VPN interface is the intended path, and that firewall rules block non-VPN traffic when VPN is down.
OpenVPN server on EdgeRouter X remote access
If you want to access your home network securely from outside, an OpenVPN server on the EdgeRouter X is a solid choice. This approach is a bit more complex because you’re issuing client certificates and wiring up access control.
What you’ll do:
– Generate or import server certificates and a CA either via your own PKI or using the VPN provider’s tools. You’ll also create client certificates for each remote user.
– Install the OpenVPN server on EdgeRouter X and configure the server to listen on a specified port with a chosen protocol UDP is common.
– Create firewall rules to only allow VPN connections from authorized IP ranges and to forward VPN clients to the LAN.
– Provide clients with the .ovpn profile or separate certs/keys to connect remotely.
High-level steps and notes:
– set interfaces openvpn server
– set interfaces openvpn server port 1194
– set interfaces openvpn server protocol udp
– set interfaces openvpn server mode server
– set interfaces openvpn server subnet 10.8.0.0/24
– set interfaces openvpn server local-address 10.8.0.1
– set interfaces openvpn server client-config-dir /config/openvpn/ccd
– Configure firewall rules to allow VPN clients to access LAN resources but restrict unnecessary access
– Export client config for remote users the EdgeOS UI usually provides a download of the .zip with certs and config
Security considerations:
– Use a robust PKI and avoid sharing client certificates. Revoke credentials if a device is lost or an employee leaves.
– Enable TLS-auth or HMAC if your OpenVPN provider or server supports it to reduce spoofing and spoofed connection attempts.
– Use strong encryption AES-256-CBC or AES-256-GCM where supported. Be mindful of processor impact on ER-X when selecting ciphers.
IPsec/L2TP on EdgeRouter X
IPsec with L2TP can be a lighter-weight alternative to OpenVPN in some setups, especially for remote access or simple site-to-site tunnels. Here’s what you need to know:
– If your VPN provider supports IPsec/L2TP for client access, configure the EdgeRouter X to establish an IPsec tunnel. This usually involves setting:
– IPSec phase 1 IKE and phase 2 ESP parameters
– A pre-shared key PSK or certificate-based authentication
– A local and remote subnet for the tunnel
– For remote access, you’ll define a user pool and associate it with the IPsec policy. For site-to-site, you’ll configure the peer the other router and the traffic selectors.
Performance and caveats:
– IPsec is generally more CPU-friendly on many devices than OpenVPN, so you may see better throughput on EdgeRouter X using IPsec, depending on the exact configuration and hardware.
– Some VPN providers or setups require specific IKE versions IKEv2 is common and particular cipher suites. If your provider doesn’t support L2TP/IPsec with EdgeRouter X, you may be stuck with OpenVPN.
– Use a strong PSK or proper certificate-based authentication.
– Ensure you have a reliable fallback path for remote access if the VPN goes down.
– Always test from an external network cell data, friend’s Wi-Fi to confirm your remote access works as expected.
Site-to-site VPN with another router
If you’re connecting two separate locations for example, a home and a tiny office or two homes with lab networks, a site-to-site VPN is the cleanest approach.
What this looks like:
– The EdgeRouter X at location A establishes a VPN tunnel to the EdgeOS device or another router at location B.
– Traffic between defined subnets LANs on each side travels through the tunnel automatically.
– You typically use OpenVPN or IPsec site-to-site for reliability and compatibility.
Key steps:
– Define the remote peer the other router’s public IP and the tunnel parameters IKE, SA, encryption.
– Create the local and remote subnet definitions so that only the intended networks flow through the VPN.
– Establish firewall rules to allow tunnel traffic but block undesired access from the tunnel.
Performance:
– Site-to-site tunnels can be more predictable than remote access since you control the remote endpoint, but throughput will still be bound by the router’s CPU and the VPN protocol.
– If you’re linking multiple sites with high traffic, consider upgrading to a router with stronger encryption acceleration or offloading capabilities.
Performance and security best practices
– Prefer UDP for VPN transport when possible to reduce overhead and improve latency.
– Keep EdgeOS firmware up to date. Ubiquiti frequently releases security and performance improvements in newer EdgeOS versions.
– Use a dedicated VPN only for specific devices or subnets if your hardware is limited and you’re seeing CPU saturation.
– Enforce DNS through the VPN to prevent leaks. push VPN DNS servers to clients or route DNS through the VPN tunnel.
– Implement a “kill switch” so that devices on your LAN don’t accidentally leak traffic if the VPN drops.
– Separate VPN traffic from regular traffic using VLANs or firewall rules to improve security and troubleshooting.
– Regularly rotate certificates and keys, especially for OpenVPN server and client certificates.
Troubleshooting VPN on EdgeRouter X
– VPN does not start: check the VPN config for syntax errors, verify certificates, and ensure the EdgeRouter clock is in sync NTP.
– VPN connects but no traffic passes: confirm routing default routes via VPN, firewall rules, and ensure the VPN interface is included in the correct firewall zones.
– DNS leaks observed: configure VPN-supplied DNS servers on the client side or route DNS queries over the VPN tunnel.
– High latency or jitter: consider switching to a lighter encryption profile or using IPsec instead of OpenVPN. verify network path quality to the VPN server.
– Tunnel randomly drops: check for IP conflicts on the VPN network, ensure keepalive/heartbeat settings are correct, and confirm there are no intermittent WAN issues.
– If you’re using a site-to-site VPN and one side can’t be reached: confirm NAT traversal rules, ensure the remote peer’s firewall allows the tunnel, and verify the exact traffic selectors.
Which path should you choose?
– If you want simplicity and broad compatibility, start with OpenVPN client on EdgeRouter X.
– If you need reliable remote access with potentially better throughput, IPsec/L2TP is a strong option.
– If you want a private link between two locations for specific subnets and traffic, a site-to-site VPN is your best bet.
– If you’re chasing performance with modern crypto, and your EdgeOS version supports it, consider WireGuard or the closest supported implementation but verify compatibility first.
– Always test in your own environment after any change to ensure no leaks and that all devices behave as expected.
