What EdgeRouter X is and why you’d run VPN on it

EdgeRouter X is a compact, budget-friendly router designed for home offices and small networks. It runs EdgeOS, which gives you a lot of the same flexibility you’d get from larger enterprise-grade routers, but in a small box. Why run a VPN on EdgeRouter X? Because it allows you to:

Encrypt traffic between your LAN and a VPN endpoint home, work, or a cloud VPC so every device on your network benefits from that encryption without configuring each client individually.
Create a secure remote access path so you can reach your home or office network from anywhere.
Do site-to-site VPNs to connect two networks as if they were on the same local network, which is great for small offices or collocated teams.
Centralize VPN management on one device rather than chasing down VPN clients on every PC, phone, and streaming device.

Performance on the ER-X will depend on encryption overhead, the VPN protocol you choose, and how heavily you’re using the router for other tasks. In practice, you’ll typically see VPN throughput in the hundreds of Mbps range on a well- configured OpenVPN UDP setup and IPsec in similar ballparks, with real-world results varying by CPU load, MTU size, and the exact cipher suite you choose. EdgeRouter X is a capable little box, but don’t expect large enterprise speeds for encryption-heavy traffic if you’re pushing a lot of clients at once.

VPN protocols supported on EdgeRouter X: OpenVPN, IPsec, and the WireGuard note

OpenVPN client and server: The most common choice for EdgeRouter X because it’s widely supported by VPN providers and can operate in both client and server modes. OpenVPN is robust, flexible, and works well with UDP for better speed, but it can be heavier on the router’s CPU when you have many VPN clients or strong encryption.
IPsec with strongSwan: A strong alternative for site-to-site connections or for clients that need a system-wide VPN that’s easy to push across multiple devices. IPsec can be faster on some configurations due to hardware acceleration availability and is excellent for site-to-site setups.
WireGuard: As of 2025, WireGuard support on EdgeRouter X/EdgeOS is less straightforward. Some users run WireGuard on EdgeRouter X through community patches or by routing traffic to a dedicated WireGuard device, but official, fully integrated support isn’t universally documented. If you’re chasing simplicity and broad compatibility, OpenVPN and IPsec remain the safer bets. If you’re a tinkerer and a good documentation reader, you can explore experimental paths, but expect more manual work and potential stability quirks.

Important note: Always verify your EdgeOS version and your VPN provider’s recommended configurations. The UI and CLI options change over time, and you may find newer EdgeOS releases have updated menu names or new features that aren’t reflected in older guides.

Choosing the right VPN setup for EdgeRouter X

Your best setup depends on your goals, number of devices, and how you plan to use the VPN. Here are practical paths:

All-in-one protection for your LAN remote access to your home network: OpenVPN client on EdgeRouter X. This allows all LAN devices to benefit from a single VPN tunnel to your chosen endpoint.
Connecting two networks site-to-site: IPsec site-to-site. Great for linking a home office to a small office or another location, with traffic between the sites being encrypted and private.
Remote access for multiple devices individual client access: OpenVPN server on EdgeRouter X in combination with a few user accounts, or IPsec remote access if your clients support it well.
Mixed needs: Run an OpenVPN server for remote clients and a separate IPsec site-to-site tunnel to another location. You’ll manage routing so that specific subnets go through VPN while others stay on the regular internet.

Decision factors: Setup vpn on edgerouter x

CPU load and VPN count: More clients mean more CPU cycles. ER-X is capable, but plan for growth.
Client devices: If you have many Windows/macOS/Linux laptops and mobile devices, OpenVPN remote access might be simpler to manage.
Remote endpoint: Do you already have an OpenVPN server or an IPsec gateway? Align your ER-X setup with the endpoint you plan to use.
Network routing needs: If you need to expose a whole LAN behind the VPN, you’ll focus more on site-to-site or remote access configurations and ensure proper NAT rules.

Step-by-step: setting up an OpenVPN client on EdgeRouter X UI-first approach

Note: The exact menu labels may vary slightly with your EdgeOS version, but the flow is the same.

Prepare your VPN provider details

Obtain from your VPN service:
- Server address or hostname
- UDP port default 1194 for many providers
- CA certificate and user certificate/key if required
- Any extra TLS settings your provider requires auth, cipher, etc.

Access EdgeRouter X via the web UI

Open a browser to the ER-X IP usually 192.168.1.1, log in with admin credentials.

Create an OpenVPN client

Navigate to VPN > OpenVPN > Client or similar.
Add a new client profile.
- Name: OpenVPN-Client-1 or whatever you prefer
- Server: enter the provider’s server address
- Port: 1194 or as provided
- Protocol: UDP commonly faster. TCP can be used if you have firewall issues
- TLS and encryption settings: set to match the provider e.g., TLS auth, cipher
- CA certificate and Client certificate/key: upload as required by your VPN provider
- Redirect gateway: enable if you want all LAN traffic to go through the VPN
Save the profile.

Create firewall and routing rules

Ensure there are firewall rules allowing VPN traffic UDP 1194 or your chosen port from LAN to WAN.
Add a routing rule so LAN traffic destined for the VPN goes through the OpenVPN interface tun or tap interface you created.
If you’re using full-tunnel all traffic via VPN enable redirect gateway. otherwise, create specific static routes as needed.

Test the VPN connection

Connect the VPN client from the EdgeRouter UI and check the status.
Verify that a client on your LAN uses the VPN by visiting an IP-check site or using a traceroute to a non-local address.
Check DNS: ensure DNS requests go through the VPN if that’s your goal. otherwise adjust DNS settings to prevent leaks.

Optional: push DNS and split-tunnel rules

If you want to avoid DNS leaks or direct only certain traffic through VPN, configure:
- DNS servers inside the VPN tunnel
- Split-tunnel rules to exclude non-critical traffic from the VPN

Maintain and monitor

Watch VPN uptime, CPU load, and WAN connectivity.
Keep your VPN client certs/keys up to date and rotate as prescribed by your provider.

High-level CLI flavor for advanced users

If you’re comfortable with EdgeOS CLI, you’ll be working under the configuration tree for vpn openvpn, adding an openvpn-client profile, and then binding it to an interface like tun0. The exact commands depend on your EdgeOS version, so refer to the EdgeRouter CLI guide and OpenVPN docs for exact syntax. The UI approach above is enough for most home and small-office setups, and CLI is mainly for power users or automation.

Step-by-step: setting up IPsec site-to-site on EdgeRouter X

If you’re linking two sites, IPsec is a clean and efficient approach.

Decide your endpoints

One site will be the initiator your ER-X, the other site runs an IPsec gateway could be another router or a cloud VM running strongSwan, for example.

Gather IPsec details

Public IPs for both sites
Shared pre-shared key PSK or certificate-based authentication
Local and remote subnets to be encrypted

Configure on EdgeRouter X UI

Go to VPN > IPsec or similar
Create a new IPsec site-to-site tunnel
- Local subnet: your LAN e.g., 192.168.2.0/24
- Remote subnet: the other site’s LAN e.g., 192.168.1.0/24
- Remote gateway: the other site’s public IP
- Authentication: pre-shared key or certificate
- Phase 1 and Phase 2 parameters: choose reasonable values AES, SHA-256, DH group 14/Modp 2048, lifetime values around 3600s and 3600s
Save the tunnel and apply changes

Create traffic selectors and routing

Add firewall rules to allow IPsec traffic ESP, AH, IKE through the WAN
Add a route for the remote subnet to go through the IPsec tunnel

Test the tunnel

Use ping/traceroute to verify connectivity across subnets
Check that traffic between sites encrypts as expected some devices show “IPsec tunnel established” in logs

Troubleshooting tips

Ensure time sync on both sides. IPsec is sensitive to clock drift
Check for NAT or firewall blocks along the path
Verify PSK matches on both ends
Watch IKE and IPsec logs for errors. common issues include misconfigured phase 1/2 params or certificate mismatches

Tiny performance and reliability tips to get the most from EdgeRouter X

Use UDP where possible: UDP VPN tends to be faster than TCP, since it has less overhead.
Tweak MTU and MSS: Start with an MTU of 1500, then adjust down in small steps if you see fragmentation or VPN instability. A common safe range is 1400–1420 for VPN paths with overhead.
Enable hardware offloading and keep EdgeRouter X firmware updated: Newer EdgeOS firmware often includes small but meaningful performance and security improvements.
Keep other services lean: If you’re running the VPN alongside firewall rules, DPI, or NAT-heavy rules, you’ll consume more CPU. Simplify rules if you’re hitting throughput ceilings.
DNS considerations: Use VPN-provided DNS to avoid leaks. you can also set DNS to a trusted resolver inside the tunnel to improve privacy.
For large remote-subnet setups: Consider IPsec for site-to-site and keep client connections lean—too many remote clients can push CPU usage up quickly.

Security best practices and maintenance

Change the default admin password and disable unused services like SSH from the WAN side when not needed.
Keep firmware up to date: EdgeOS updates often include security fixes and performance improvements.
Separate VPN admin access from general LAN access: Use strong authentication, ideally with certificate-based FSAs or complex pre-shared keys if certificates aren’t available.
Monitor VPN logs: Regularly review logs for unusual activity or failed VPN attempts and adjust firewall rules accordingly.
Back up your configuration: Save your EdgeRouter X config after successful VPN setup. test restore to ensure you can recover quickly in a disaster scenario.

Real-world tips and sanity checks

Start small, then scale. Begin with a single OpenVPN client or a single IPsec tunnel, verify everything works, then slowly add more tunnels or users.
Use a simple, readable naming scheme for VPN profiles to avoid confusion as you expand.
Document your setup. Keep a short write-up of which tunnels exist, their purpose, and which subnets are routed through them.
Keep backups. Save a current EdgeRouter X configuration after any VPN changes and store a copy somewhere safe.
