Understanding the EdgeRouter X VPN capabilities
The EdgeRouter X is a compact but capable router that runs EdgeOS, which is based on a VyOS-like concept. It supports VPN functionality through OpenVPN and can also handle IPsec/SITE-TO-SITE configurations with proper tooling. Real-world VPN throughput on the EdgeRouter X depends heavily on CPU load, encryption, and whether you’re routing all traffic through the VPN full tunnel or just specific subnets. Expect practical OpenVPN client throughput in the tens to low hundreds of Mbps range on typical home internet connections, with performance varying by firmware version and configuration.
Key things to know:
– OpenVPN server and client modes are available in EdgeOS, which means you can both connect to a VPN provider and accept connections from remote clients.
– For site-to-site connections, you’ll typically use IPsec/SITE-TO-SITE with proper matching policies, but OpenVPN remains a flexible option for quick setups and mobile clients.
– DNS handling matters. If you route all traffic through VPN, you’ll want to ensure DNS requests also go through the VPN to prevent leaks.
Prerequisites
Before you start, gather these:
– A working EdgeRouter X with the latest EdgeOS firmware or a recent stable release.
– Administrative access to the EdgeRouter X GUI via 192.168.1.1 or your assigned IP.
– A VPN provider account if you’re setting up a client connection for example, OpenVPN-compatible configs from NordVPN, ExpressVPN, ProtonVPN, etc..
– The VPN provider’s required files or credentials: OpenVPN config .ovpn, CA certificate, client certificate, and client key if required, or a username/password option depending on the provider.
– A basic backup of your current EdgeRouter configuration in case you need to revert changes.
What we’ll do in this guide:

– Quick troubleshooting tips and performance notes
Quickstart: OpenVPN client to a VPN provider
This section walks you through setting up the EdgeRouter X as an OpenVPN client that tunnels all internet traffic through your VPN provider. If you already have an ovpn file from your provider, you can import it or copy the necessary fields into the EdgeOS GUI.
# Step 1 — Prepare your OpenVPN materials
– Obtain an OpenVPN configuration file .ovpn from your VPN provider, ideally with a UDP connection on a recommended port often 1194.
– If your provider uses certificates, copy the CA certificate ca.crt, client certificate client.crt, and client key client.key. If the provider uses a username/password, have those ready as well.
– Decide whether you want all traffic to go through the VPN full tunnel or just specific subnets.
# Step 2 — Access EdgeRouter X and locate VPN settings
– Open a web browser and go to the EdgeRouter X’s GUI commonly 192.168.1.1.
– Log in with admin credentials.
– Navigate to the VPN section. In modern EdgeOS versions, you’ll find OpenVPN options under VPN or Services.
# Step 3 — Create an OpenVPN client
– Add a new OpenVPN client often labeled as a “VPN Client” or “OpenVPN Client”.
– Configure the connection:
– Server address: the VPN provider’s server or host from the .ovpn file.
– Port: 1194 or the port your provider specifies.
– Protocol: UDP or TCP UDP is common for speed. TCP can be more reliable on flaky connections.
– Remote network: typically 0.0.0.0/0 when you want all traffic routed through the VPN.
– Certificates and credentials:
– Paste or import the CA certificate contents.
– Paste or import the client certificate and key if required by your provider.
– If using username/password, enter them here or use an authentication file if your provider supports it.
– If your provider gives you an ovpn profile, you can paste the entire content into the appropriate fields or upload if the UI supports file import.
# Step 4 — Configure DNS and routing
– DNS: set DNS to a provider DNS like 1.1.1.1 or 9.9.9.9 or allow the VPN to supply DNS. Some providers push DNS servers via the VPN tunnel. others require manual settings.
– Routing: enable a default route via the OpenVPN interface so all traffic goes through the VPN by default. In EdgeOS, this is typically done by selecting the VPN interface as the next hop for 0.0.0.0/0.
– If you want a split-tunnel only some traffic via VPN, set a static route and firewall policy for the subnets you want to route through the VPN.
# Step 5 — NAT and firewall considerations
– NAT: For a standard home setup, you still NAT LAN clients to the WAN or VPN interface as appropriate. If you’re forcing all traffic through the VPN, you’ll generally keep NAT on the WAN interface for LAN-originated traffic unless you’re setting up a strict VPN-only path for all devices.
– Firewall: Allow VPN traffic on the firewall. Create an inbound/forward rule permitting traffic from LAN to VPN interface, and outbound rules allowing VPN traffic to the internet. A basic rule set often looks like:
– Allow: from LAN to VPN interface stateful
– Allow: VPN interface to WAN
– Deny: other unsolicited traffic as per your security posture
# Step 6 — Enable, test, and monitor
– Save and apply the configuration.
– Check the VPN status indicator in the GUI to ensure the tunnel is up.
– Test your public IP: visit a site like whatismyipaddress.com to confirm the IP shown is from the VPN provider.
– Verify DNS leaks by visiting dnsleaktest.com or similar sites.
– If you encounter disconnects, enable auto-reconnect or re-authentication in the VPN settings, and ensure the server address and credentials are correct.
# Step 6.5 — Practical tips for a smooth OpenVPN client setup
– Use the provider’s recommended server for performance and reliability. many providers offer separate servers optimized for streaming or gaming.
– If you see frequent DNS leaks, switch to a DNS pulled from the VPN or set a DNS in EdgeOS that only resolves through the VPN.
– For mobile devices or laptops that switch networks, consider leaving OpenVPN in a “keepalive” mode so it re-establishes quickly when networks change.
Advanced: OpenVPN server on EdgeRouter X for remote clients
If you want to let remote devices connect to your home network a small VPN server, you can configure the EdgeRouter X as an OpenVPN server. This lets you access your home network securely from anywhere and can be a good alternative if your VPN provider doesn’t support a reliable client route for your devices.
# Step-by-step outline
1. Generate certificates and keys for the server and clients, or use a centralized CA if you have one.
2. Enable OpenVPN server mode on EdgeRouter X.
3. Configure server parameters:
– Server mode: tun0
– Protocol: UDP commonly 1194
– Server network: e.g., 10.8.0.0/24
– Client config: push routes to access LAN resources
4. Create user accounts for remote clients and provide them with a .ovpn profile that points to your EdgeRouter X.
5. Set up firewall rules to allow VPN connections and to restrict access as needed.
6. Test from a remote network, verifying you can access local LAN resources printers, NAS, and other devices.
7. Monitor and adjust MTU and keepalive settings to keep the tunnel stable on variable networks.
Notes:
– Running your own OpenVPN server at home gives you full control but requires more maintenance.
– If you need simpler remote access, relying on a trusted VPN provider is often easier.
Optional: IPsec/SITE-TO-SITE and alternative VPN methods
EdgeRouter X can work with IPsec for site-to-site connections. If you’re connecting two networks you control for example, your home network and a remote office or another home lab, IPsec/SITE-TO-SITE can be more stable and performant for constant connections. The setup tends to be more involved and may require additional firmware features. If you’re new to VPNs, starting with OpenVPN client setup described above is usually easiest. you can expand to IPsec as you gain confidence.
DNS, privacy, and kill switch considerations
– DNS leakage prevention: ensure DNS requests go through the VPN by using VPN-provided DNS servers or by configuring DNS in EdgeOS so that DNS remains within the VPN tunnel.
– Kill switch: maintain a strict rule set that drops traffic if the VPN tunnel goes down, rather than letting your traffic leak through the default WAN. You can implement this by using policy-based routing and firewall rules that force all LAN traffic to the VPN interface when the tunnel is up and drop it if the tunnel is down.
– Regular backups: keep a backup of your EdgeRouter X configuration before making VPN changes. It makes recovery quick if something goes sideways.
Performance considerations and real-world numbers
– VPN adds encryption overhead, so your real-world throughput will drop from the raw WAN speed. Depending on encryption level and CPU usage, you might see noticeable drops, especially on a budget device like the EdgeRouter X.
– If you’re streaming 4K video or gaming, test with your specific provider’s server and adjust the tunnel type UDP vs TCP to optimize reliability and latency.
– For many homes with symmetrical gigabit connections, a well-tuned OpenVPN client on EdgeRouter X should comfortably handle typical browsing and video streaming, but expect some dip under heavy simultaneous loads.
– If you hit performance bottlenecks, consider limiting VPN use to specific services or devices, upgrade firmware, or explore a higher-end router with more CPU headroom for VPN workloads.
Common pitfalls and how to fix them
– VPN tunnel won’t come up: double-check server address, port, protocol, and credentials. verify that the server is not blocked by your ISP. ensure you pasted the CA certificate and client cert/key correctly.
– DNS leaks: switch to VPN-provided DNS servers or override DNS on the router to a non-leak-prone resolver that’s reachable only when the VPN is up.
– Split-tunnel confusion: decide early if you want all traffic via VPN or only selected subnets. misconfiguring routes can leave some devices using the wrong path.
– NAT and firewall conflicts: ensure NAT rules and firewall policies allow the VPN traffic and don’t block traffic from LAN to VPN or vice versa.
– VPN stability: enable auto-reconnect, adjust keepalive settings, and consider a backup VPN server if your provider supports it to avoid long outages.
