Understanding what EdgeRouter X can do for VPNs
EdgeRouter X from Ubiquiti runs EdgeOS and is a popular budget option for home labs and small offices. It supports:
- OpenVPN server for remote access, letting you securely reach your home network from anywhere
- OpenVPN client to connect to a VPN provider, so your traffic can route through a VPN tunnel
- Basic IPsec site-to-site capabilities in some setups, though most home users stick to OpenVPN for ease
- Firewall rules and NAT to isolate and protect VPN clients
- Reasonable performance for typical home internet plans, with speeds heavily influenced by CPU usage during encryption
A couple of real-world notes to keep in mind:
- VPN performance on EdgeRouter X depends on CPU load. OpenVPN is CPU-intensive, so expect some slowdown compared to unencrypted traffic.
- If you’re aiming for “all traffic through VPN” from devices on your LAN, you’ll want to configure NAT and routing carefully so VPN clients can reach LAN resources and browse securely.
- For frequent remote access users, a clean client config with proper certificates makes life easier than juggling username/passwords.
What you’ll need before you start
- An EdgeRouter X already up and running on your network latest stable EdgeOS
- A computer or laptop to access the EdgeRouter web UI 192.168.1.1 by default
- Administrative access to EdgeRouter X admin credentials
- For OpenVPN server: a certificate authority CA, a server certificate, and client certificates or a plan to generate them within EdgeOS
- For OpenVPN client: a VPN provider account or your own VPN server details server address, port, protocol, and credentials
- Basic firewall understanding to create VPN-friendly rules
- Optional: a VPN service like NordVPN for remote access testing or secondary security via a provider

Step-by-step setup high level, UI-first approach
- Access EdgeRouter UI
- Open a browser and go to https://192.168.1.1 or the EdgeRouter’s IP on your LAN
- Log in with admin credentials
- Prepare certificates CA, server, client
- In EdgeOS, you typically create a CA, then a server certificate, and finally certificates for each client.
- If your EdgeOS version supports it, you’ll see a VPN/Certificate management area. Create:
- A new Certificate Authority CA
- A server certificate signed by that CA
- Client certificates for your users or export a client config that embeds the client cert
- Create the OpenVPN server
- Navigate to VPN > OpenVPN Server or VPN > OpenVPN, depending on your EdgeOS version
- Set the server mode to “Server” not client
- Protocol: UDP recommended for performance
- Port: 1194 default. you can use another if needed
- Server network: 10.8.0.0/24 example. you can use another private network
- Encryption: AES-256-CBC or AES-256-GCM if available
- Compression: disabled security note
- TLS/auth: enable if available and generate a shared TLS key
- Certificate: select the server certificate you created
- Client authentication: require certificate preferred over password only
- Create a VPN user client
- Create a client entry often called a user or client profile
- Generate or assign a client certificate and key for this user
- Optionally set a password if you’re using certificate + password authentication
- Configure firewall and NAT
- Allow UDP 1194 in the EdgeRouter firewall create a rule to permit inbound VPN traffic
- Create a NAT rule so VPN clients can access the internet through the EdgeRouter:
- Source: 10.8.0.0/24 your VPN network
- Outbound interface: your WAN
- Action: masquerade
- Add filtering so VPN clients can access LAN resources safely if you want to enable access to LAN subnets define traffic rules accordingly
- Export or assemble the client config
- EdgeRouter can export an OVPN profile or provide the necessary certificates and keys to assemble your client config
- Download the .ovpn file or copy the embedded certificates and keys to your client device
- Connect from a client device
- Install OpenVPN client on Windows/macOS/iOS/Android
- Import the .ovpn profile or manually configure with the server address, port, protocol, and credentials
- Connect and verify by checking your external IP and pinging a LAN host
- Verify and test
- Check that your public IP matches the VPN exit point
- Verify that LAN resources you expect to reach are reachable
- Confirm there are no DNS leaks by using a DNS leak test
- Troubleshooting tips OpenVPN server
- If clients can’t connect, recheck certificates and their validity periods
- Ensure the server certificate matches the CA and that the client certs are properly signed
- Confirm firewall rules are not blocking UDP 1194
- Check the EdgeRouter logs for VPN-related messages to pinpoint misconfigurations
- Security and maintenance
- Rotate certificates periodically and revoke clients you no longer use
- Disable any unused VPN features to minimize attack surface
- Regularly update EdgeOS to benefit from security fixes
OpenVPN client on EdgeRouter X connect EdgeRouter X to a VPN provider
This setup is handy if you want all traffic from your entire network to go through a VPN tunnel to a VPN provider. It’s a little more involved because you’re acting as a VPN client rather than a server.
- Prepare the provider profile and credentials
- Sign up for your VPN provider NordVPN, ExpressVPN, or another
- Download the OpenVPN configuration files and required certificates/keys
- If the provider uses a single config file with embedded certificates, you’re good to go. otherwise separate the certs/keys as needed
- Upload and configure on EdgeRouter X
- In EdgeOS, go to VPN > OpenVPN Client or Client VPN depending on UI
- Add a new client instance
- Server address and port: enter the VPN provider’s server details
- Protocol: UDP common for OpenVPN
- TLS/CA: upload the CA certificate. import client certificate and key if required
- Authentication: provide the client certificate or username/password if the provider uses that method
- Enable “redirect-gateway” or “pull” depending on your edge settings to force all traffic through the VPN
- Save and apply
- Routing and NAT for VPN client
- Ensure there’s a route for VPN traffic and that the VPN’s virtual interface is allowed through the firewall
- If you want all devices on your LAN to go through the VPN, you may need to add a static route in EdgeRouter for the VPN interface to the desired internet path
- Verify that the VPN client’s tunnel is up and check the interface status
- DNS considerations
- To avoid DNS leaks, set your clients to use the VPN provider’s DNS or a trusted DNS like Cloudflare 1.1.1.1 over the VPN
- In EdgeRouter, you can set DNS servers for VPN clients or push DNS options through the VPN client config
- Testing
- Check your public IP uses the VPN provider’s exit node
- Test for leaks with online tools
- Test access to local LAN resources if needed
- Troubleshooting VPN client issues
- If the tunnel won’t come up, verify certificate validity and the CA chain
- Check for IP conflicts on the LAN side that could disrupt VPN routing
- Confirm the VPN provider allows multiple simultaneous connections and isn’t blocking EdgeOS clients
- Performance considerations
- VPN tunnel encryption adds overhead. expect some slowdown depending on your internet speed and the VPN protocol
- UDP generally gives better performance than TCP for VPN traffic
- If you notice instability, try a different server location from your provider or adjust MTU settings to avoid packet fragmentation
Split tunneling vs. full tunneling on EdgeRouter X
- Split tunneling: only traffic destined for certain networks or subnets goes through the VPN. other traffic leaves directly through your normal ISP.
- Full tunneling: all traffic from every device on the LAN routes through the VPN tunnel. This is simpler for privacy but can reduce speed and increase latency.
Pros and cons: Ubiquiti edge router site to site vpn
- Split tunneling reduces bandwidth pressure on the VPN and can improve speeds for local network devices.
- Full tunneling offers more privacy and security for all traffic but requires careful routing and firewall rules to avoid leaks or accessibility issues.
Tips to implement safely:
- Start with split tunneling, then test adding full tunneling if you need all traffic protected.
- Use DNS protection to prevent leakage when split tunneling is enabled.
- Regularly audit firewall rules to ensure no traffic bypasses VPN protection unintentionally.
Security best practices for EdgeRouter X VPN setups
- Keep EdgeOS up to date with the latest security patches.
- Use strong, unique certificates for VPN clients and servers.
- Enforce certificate-based authentication over username/password alone where possible.
- Disable unused VPN features to minimize the attack surface.
- Regularly back up your VPN configuration and certificate material.
- Use a DNS provider you trust and consider DNS over HTTPS DoH if available on your clients.
- If you enable remote access, require MFA on your VPN client accounts where possible.
Performance and data points you can expect
- EdgeRouter X is a compact device with enough horsepower for typical home and small-office tasks, but VPN encryption especially OpenVPN is CPU-intensive.
- Real-world VPN speeds depend on your internet plan, the VPN server location, and encryption settings.
- Expect some reduction in throughput when VPN is enabled. If your internet plan is fast e.g., 500 Mbps+, you may see noticeable slowdowns with OpenVPN. using lighter ciphers or different VPN protocols like WireGuard, if your EdgeOS version supports it via updates can help, though WireGuard support on EdgeRouter X may require newer firmware and compatible modules.
- For remote access with a small number of clients, the EdgeRouter X can handle multiple concurrent OpenVPN clients without hitting plateaus in typical home setups.
Common pitfalls and how to avoid them
- Mispaired certificates: Always ensure the CA, server cert, and client certs are correctly signed and matched.
- Port and firewall misconfig: If VPN clients can connect but can’t reach the LAN or the internet, re-check NAT and firewall rules, especially for the VPN network.
- DNS leaks: If you’re using VPNs for privacy, keep DNS queries within the VPN tunnel and configure your devices to use VPN-provided DNS or trusted DNS over VPN.
- IP conflicts on LAN: Ensure VPN client networks don’t overlap with existing LAN subnets. plan subnetting accordingly.
- Firmware compatibility: Newer EdgeOS versions often improve VPN features. upgrading can bring better OpenVPN support and stability.
