EdgeRouter X ER-X is a small, affordable router that runs EdgeOS. It’s powerful enough for many home networks and even small offices, and it’s flexible enough to host a VPN server or be part of a VPN client chain. The big win is you don’t need a separate VPN appliance. you can route all remote traffic through your home network, access devices as if you’re on-site, or securely connect two locations with a site-to-site VPN.
OpenVPN and WireGuard are two approachable options. OpenVPN is mature, widely supported, and firewall-friendly on many setups. WireGuard is faster and simpler in many scenarios, but WireGuard support on ER-X depends on your EdgeOS version and hardware capabilities, so check your build before you commit.
If you’re new to EdgeOS, think of VPNs here as a way to: a access your home network remotely, b protect traffic on your mobile devices when you’re on public Wi‑Fi, and c connect multiple sites securely without paying for extra gear.

Prerequisites you’ll want before you start

Hardware: an EdgeRouter X with a stable power supply, connected to your LAN, and a device you’ll use to configure the router PC or laptop.
Firmware: make sure you’re running a recent EdgeOS version that supports OpenVPN server and, if possible, WireGuard. If you’re unsure, check the EdgeRouter knowledge base for your exact model.
Internet connection with a public IP or dynamic DNS plan dynamic DNS helps if your public IP changes.
Basic familiarity with the EdgeOS web UI. A little CLI familiarity helps for troubleshooting, but you can do most tasks in the GUI.
A client device for testing Windows/macOS/Linux/iOS/Android and a way to import or copy the VPN profile.
Optional: a VPN provider account if you want to route traffic through a commercial VPN service rather than hosting your own.

OpenVPN on EdgeRouter X: setup guide GUI-first
Overview

OpenVPN server on ER-X is a solid, battle-tested choice for reliable remote access. You’ll set up a VPN server, create user credentials, configure the server network, and export a client profile that you’ll install on your devices.
In most EdgeOS builds, you’ll find the OpenVPN server under the VPN section of the GUI. You’ll specify the server’s network like 10.8.0.0/24, encryption, and authentication settings, plus DNS. You’ll also configure firewall rules to allow inbound VPN connections and to control what VPN clients can access.

Step-by-step GUI-oriented, with CLI notes

Update EdgeRouter

Log in to the EdgeRouter GUI https://router.local or 192.168.1.1.
Go to System and apply any available updates to ensure you’ve got the latest OpenVPN features and bug fixes.

Prepare the OpenVPN server

Navigate to VPN > OpenVPN Server.
Enable OpenVPN server and choose UDP often simpler and faster for remote access. Common port choices are 1194 or another port you prefer if you’re behind strict NAT.
Set the server network, e.g., 10.8.0.0/24, and define a DNS server for VPN clients this can be your home router’s IP or a public DNS server.
Pick an encryption cipher and TLS authentication settings. For security, use modern ciphers AES-256-CBC or AES-256-GCM where available and a TLS-auth key or TLS-crypt if supported.
Create at least one user, with a username and password. If you can, prefer certificate-based authentication or use TLS authentication for additional security.

Generate client profiles

In the same VPN OpenVPN Server area, export or generate a client profile. This will produce an OpenVPN .ovpn file or a set of files you can import into an OpenVPN client app.
If your EdgeOS GUI doesn’t offer a direct export, you can copy the server config and TL-S key and assemble a client profile manually, but most users find the built-in export easiest.

Adjust firewall rules

Ensure the EdgeRouter firewall allows inbound VPN traffic on the chosen port 1194 UDP by default.
Create a NAT rule to let VPN clients access the LAN. A typical rule is: Source NAT VPN network to the LAN network, so VPN clients appear as local devices when they access LAN resources.
If you plan to push DNS or route-only traffic, configure push routes accordingly and consider splitting tunnel rules if you want to keep some traffic local.

Allow VPN clients’ LAN access

In OpenVPN server settings, set the appropriate route-push options so clients can reach devices on your LAN e.g., 192.168.1.0/24.

Test connectivity

Import the .ovpn profile into a VPN client on a phone or laptop.
Connect from a different network cell data or a friend’s Wi‑Fi to verify the tunnel works and you can access LAN resources or public IP.

Troubleshooting tips

If you don’t see the tunnel, verify port forwarding and firewall rules. Verify the server is listening on the expected port.
Check the client logs for TLS handshake errors or authentication failures.
Confirm the VPN IP address assigned to clients doesn’t collide with your LAN addressing.

OpenVPN on EdgeRouter X: security and best practices

Use TLS authentication TLS-auth or TLS-crypt if your EdgeOS version supports it. it adds a hurdle for attackers trying to probe your VPN.
Prefer certificate-based authentication if possible. password-based VPNs are easier but less secure against credential stuffing and brute force.
Consider limiting VPN access to only necessary subnets or devices to minimize risk in case a client device is compromised.
Regularly rotate client certificates/keys and keep firmware up to date.

WireGuard on EdgeRouter X: what you need to know Edgerouter show vpn config

WireGuard is a lean, fast alternative to OpenVPN, with simpler configuration and often better performance. However, WireGuard support on EdgeRouter X depends on your EdgeOS version and the router’s capabilities. Some ER-X builds offer native WireGuard support, while others may require community workarounds or not support it at all.
If your EdgeOS version includes WireGuard:
- You’ll create a WireGuard interface, generate a private/public key pair, and configure peers with their public keys and allowed IPs.
- You’ll set a listening port and assign a VPN subnet for example, 10.9.0.0/24 for WG clients.
- Firewall and NAT rules will route traffic from the WG interface to your LAN, just like with OpenVPN.
If your version doesn’t natively support WireGuard, you have two options: stay with OpenVPN as your primary remote-access solution, or explore community builds or newer EdgeRouter firmware that adds WG support. Always back up your config before attempting significant changes.

Step-by-step WireGuard, when supported

Verify WG support

Check EdgeOS or ubnt forums to confirm WireGuard support for your exact ER-X/EdgeOS version.

Create WG interface

In the GUI, add a WireGuard interface e.g., wg0 and generate a private key for the router.

Configure server peers

Define allowed IP ranges for clients, assign each client a public key, and specify the allowed localhost subnets for routing.

Firewall and NAT

Open the WG port default 51820 UDP and set NAT routing so WG clients can reach LAN resources.

Client configuration

Generate client configs with the router’s public key and the server’s public key. distribute to clients to import into their WireGuard apps.

Test

Bring up the tunnel on a client device and verify connectivity to LAN devices and Internet access via the VPN path.

Security notes

WireGuard uses modern cryptography and a smaller attack surface. Keep private keys secure and rotate them as needed.

Remote access vs site-to-site VPN on the ER-X

Remote access VPN your typical road-warrior setup lets individual devices connect to your home network securely when they’re away. It’s convenient for laptops, phones, and tablets.
Site-to-site VPN connects entire networks for example, your home office and a branch office. It requires coordination of subnets and routing rules, but it’s seamless for devices on both sides as if they’re on the same LAN.
ER-X can support both, but you’ll configure the VPN profiles differently and plan your subnets to avoid overlaps. In many homes, a remote-access OpenVPN or WireGuard setup meets most needs, while a separate site-to-site is ideal for multi-site families or small offices.

Security best practices for ER-X VPNs

Always use strong credentials and consider certificate-based auth for OpenVPN if possible.
Keep EdgeOS and all firmware up to date. apply security patches promptly.
Limit VPN access to only what’s necessary. use firewalls to restrict VPN users to the subnets they need.
Consider using a reputable VPN provider for extra encryption and privacy benefits when routing traffic through their servers, but be mindful of provider terms and device compatibility.
Regularly review logs for unusual activity and rotate keys/certificates on a schedule.

Performance tips to get the most from your ER-X VPN

Encryption choice matters. AES-256-GCM if available is fast and secure. avoid older ciphers that hurt performance.
Choose UDP for OpenVPN if possible to reduce overhead. TCP can be more stable on flaky networks but slower.
If you have a mixed LAN, consider splitting VPN traffic so only traffic destined for the LAN goes through the VPN, while other traffic uses your local ISP.
For WireGuard, keep the allowed IPs tight to limit unnecessary routing and reduce CPU load.
If you need more bandwidth than ER-X can handle with VPN encryption, consider upgrading to a higher-end edge router or placing the VPN on a dedicated device in your network e.g., a small server or Raspberry Pi while keeping the ER-X as the main router.

Port forwarding and firewall misconfiguration: ensure the VPN service port is open and mapped, and that the VPN interface is included in the firewall zone with proper rules.
IP address conflicts: avoid overlapping VPN subnet ranges with your LAN. Plan subnets carefully for example, LAN 192.168.1.0/24 and VPN 10.8.0.0/24.
DNS leaks: configure VPN clients to use VPN-provider DNS or your home DNS so traffic doesn’t leak outside the VPN.
Dynamic IP issues: if your public IP changes, set up dynamic DNS to keep remote clients from losing connectivity.
Client export issues: some OpenVPN clients require a single .ovpn file. if you’re missing certs or keys, re-export or reconstruct the client profile carefully.

Real-world use cases with ER-X VPN

Remote access to home network: you can reach your NAS, security cameras, and media server as if you’re at home.
Safe browsing on public Wi‑Fi: all traffic from your phone or laptop travels through your home network’s security.
Family-friendly VPN: keep devices connected to a trusted network even when traveling.
Small office or home office: site-to-site VPN links two locations so printers, file shares, and internal apps are accessible without exposing them to the Internet.

VPN providers and EdgeRouter compatibility

You can connect ER-X to a VPN provider as a client, but provider-specific configurations can vary. OpenVPN is generally compatible with many providers, but WireGuard compatibility depends on the provider and the EdgeOS version. If your goal is to browse from your ER-X through a provider’s secure network, review provider guides for OpenVPN or WireGuard client configs and adapt them to EdgeOS if possible.
If you’re after easy, out-of-the-box VPN experience on many devices, a reputable provider’s app is often easier, but you’ll miss the “house-wide” VPN routing that a home-run OpenVPN/WireGuard server offers.

Backups and maintenance

Always back up your EdgeRouter config before making VPN changes. Save a copy of the running-config and startup-config, so you can revert if something goes sideways.
After firmware updates, verify VPN services again. Sometimes settings drift during upgrades, and a quick re-check saves headaches later.
