Important note about stats and context
- VPN adoption is on the rise, with more households hosting multiple devices that demand private, encrypted connections. Industry forecasts consistently show continued growth driven by remote work, streaming privacy concerns, and the need to bypass geo-restrictions. While exact numbers vary by source, you’ll hear terms like “double-digit growth year over year” and “tens of billions in market size by the late 2020s.” Use these figures as context: your choice to run VPN on EdgeRouter X fits into a broader trend toward flexible, self-hosted privacy solutions.
- Real-world performance on EdgeRouter X varies. OpenVPN, especially on a modest CPU, will reduce raw throughput. Expect a few tens of Mbps for secured traffic depending on ciphers, MTU, and enabled features. IPsec tends to be a bit more efficient on many devices, but still influenced by CPU load and network conditions. Plan accordingly and consider splitting traffic or using VPN selectively to keep your main network responsive.

Why VPN on EdgeRouter X?
EdgeRouter X is a compact, affordable, and highly configurable router that runs EdgeOS. It’s perfect if you want:
- Direct control over VPN settings without subscribing to a cloud router
- The ability to host a VPN server for remote access you can connect from laptops, phones, or other devices
- Site-to-site VPN connections to a remote office or trusted partner network
- Fine-grained firewall rules and NAT control to limit exposure while a VPN is active
On the downside, it’s a budget device with limited CPU power compared to enterprise-grade gear. Heavy, sustained OpenVPN traffic can saturate the router more quickly than IPsec or lighter VPN profiles. If you expect to push a lot of traffic through a VPN, you’ll want to route critical devices through the VPN and keep non-critical traffic on your regular WAN path, or consider an upgrade more on that later.
VPN options you can use on EdgeRouter X
- OpenVPN server: Full remote access and client configuration on EdgeRouter X. Good for Windows, macOS, Linux, iOS, and Android clients.
- OpenVPN client: Connect the EdgeRouter X to a VPN provider, so all or selected traffic routes through the provider.
- IPsec Site-to-Site and remote access: Strong, widely supported, and often more efficient than OpenVPN on modest hardware.
- WireGuard: Not officially built into EdgeOS on the ER-X as of the latest stable releases. some users experiment with community packages or newer EdgeOS builds, but it’s not a guaranteed, supported option on all ER-X firmwares. If you need WireGuard specifically, you may want to run it on a separate device or plan for a hardware upgrade.
Hints for choosing:
- For remote access with multiple devices, OpenVPN server is straightforward and well-supported.
- For site-to-site branches or multiple sites with low overhead, IPsec is typically faster on limited hardware.
- If you want the simplest possible client setup on a phone or laptop, a VPN provider’s OpenVPN client or WireGuard is common, but you’ll be managing the client config rather than EdgeRouter X as the VPN endpoint.
OpenVPN server on EdgeRouter X: step-by-step
Note: This section covers a typical OpenVPN server setup on EdgeRouter X. Your exact menu names may vary slightly by EdgeOS version, but the overall steps are consistent.
What you’ll need: Planet vpn firefox extension setup and optimization guide for privacy, security, streaming, and performance on Firefox
- An ErX device with EdgeOS firmware updated to a recent version
- A public IP or a reliable dynamic DNS setup
- A set of certificates or a simple TLS-auth method we’ll use TLS-auth for security
- Basic familiarity with SSH or the EdgeOS web UI
High-level steps:
- Install or enable OpenVPN on EdgeRouter X
- Use the EdgeOS CLI or Web UI to enable OpenVPN server functionality.
- Create a certificate authority and a server certificate if you’re generating your own certificates. Some people use Easy-RSA tools. others reuse simple TLS keys depending on your chosen authentication method.
- Configure server settings
- Choose a tunnel network e.g., 10.8.0.0/24 and a DNS server for VPN clients you can push your home DNS or a public one like 1.1.1.1.
- Enable TLS-auth ta.key and select an encryption cipher AES-256-CBC or ChaCha20-Poly1305 if supported by your EdgeOS version.
- Set a client config directory path and generate client profiles for devices you want to connect.
- Add firewall rules and NAT
- Allow UDP port 1194 default for OpenVPN or your chosen port in the EdgeRouter firewall.
- Create a firewall rule that allows VPN traffic to enter the VPN server, and ensure NAT for VPN clients so they can reach the internet through the tunnel.
- Create client configs
- Generate or export client certificates and a client.ovpn file for each device that will connect to the OpenVPN server.
- For mobile devices, you can import the .ovpn profile directly into OpenVPN Connect or your chosen client.
- Test the VPN
- Start the OpenVPN service and attempt a connection from a client. Verify IP address, DNS resolution, and that traffic is routing through the VPN.
- Security tips
- Use TLS-auth and a strong cipher. keep the server and client certificates current.
- Disable password-based authentication for the management interface. use SSH keys or equivalent.
- Log VPN activity and monitor for unusual connections.
What to expect in terms performance
- OpenVPN is robust but can be CPU-intensive on a low-power EdgeRouter X. Expect modest throughput on a busy tunnel, especially with higher-end ciphers and TLS overhead. If you’re seeing latency or slow speeds, consider limiting the number of concurrent VPN clients or using IPsec for remote access where feasible.
OpenVPN client on EdgeRouter X: step-by-step
If you want EdgeRouter X to route traffic through another VPN provider, you’ll configure it as an OpenVPN client.
- A VPN provider that supports OpenVPN and provides a .ovpn profile or server address, port, protocol, and credentials
- An EdgeRouter X with OpenVPN client support same EdgeOS version considerations apply
- Obtain the OpenVPN configuration from your provider
- Download the .ovpn profile along with any CA certificates needed for the connection.
- Prepare the EdgeRouter X
- If your provider uses TLS or client certificates, import those into the EdgeRouter X configuration. Some providers offer a single .ovpn file. you may need to extract keys and certificates.
- Configure the OpenVPN client
- Create a VPN client interface e.g., tun0 and set the remote server address, port, and protocol.
- Provide auth credentials if required and point to the CA/root certificate.
- Route traffic to the VPN
- Decide which subnets should go through the VPN tunnel. You can route all traffic or just specific LAN subnets.
- Implement policy-based routing if you want split tunneling e.g., only traffic destined for certain IP ranges uses the VPN.
- Adjust firewall rules
- Allow VPN interface traffic in the firewall and set NAT rules if you want VPN-only devices to reach the internet via the VPN.
- Verify connection
- Check the VPN status, test an external IP from a connected device, and ensure DNS requests are resolving through the VPN if desired.
Performance considerations
- Client mode usually provides better throughput than hosting servers on a budget router, because you’re offloading the VPN encryption to the provider’s endpoint rather than doing all the work on ER-X. Still, you’ll face CPU limits on the router if you push many devices through the VPN.
IPsec: site-to-site and remote access on EdgeRouter X
IPsec is a solid alternative when you need efficiency and reliability. It’s great for site-to-site tunnels between branch offices or for remote-access VPNs with compatible clients. Who own k electric
What you’ll typically implement:
- Site-to-site IPsec between EdgeRouter X and another VPN gateway could be a remote office router or a firewall appliance
- Remote-access IPsec where individual clients connect securely to your home network
General steps:
- Define the phase 1 and phase 2 parameters
- Establish a shared secret or use certificates, select the encryption algorithm AES, hash SHA-256/384, and PFS group e.g., group14 or group16.
- Create a peer
- Point EdgeRouter X to the remote gateway’s IP address and authentication method.
- Configure the interesting traffic
- For site-to-site, specify the local and remote networks that should route through IPsec.
- For remote access, configure a subnet behind your EdgeRouter X that remote clients will be assigned when they connect.
- Set up firewall and NAT
- Allow IPsec protocols ESP, AH and UDP 500/4500 for NAT-T in the firewall rules.
- Create appropriate NAT rules if you want VPN clients or remote subnets to access the internet through the VPN tunnel.
- Test and monitor
- Use ping tests to the remote networks, check log entries, and validate that traffic is encrypted over IPsec.
Performance expectations
- IPsec generally runs more efficiently on modest hardware than OpenVPN, so you may see higher throughput with fewer CPU cycles spent on encryption. The ER-X should handle modest IPsec tunnels well, but throughput still depends on the selected ciphers and the number of concurrent VPN connections.
DNS, firewall, and NAT considerations
- DNS leaks: If you want all DNS queries to go through the VPN, push a DNS server into the VPN profile or configure your VPN to set DNS on VPN clients.
- Split-tunneling: Decide if you want all traffic to go through the VPN or only specific subnets. Implement policy-based routing or appropriate firewall rules to enforce this.
- Firewall discipline: Lock down VPN interfaces with tight rules. Only allow necessary ports, and consider whitelisting devices that should be allowed to connect to the VPN.
- NAT rules: For VPN clients, NAT often makes sense when you want to share a single public IP for your private network behind the VPN.
Performance optimization and practical tips
- Don’t overdo encryption. If you don’t need the highest security for every device, you can swap to less CPU-intensive ciphers e.g., AES-128-GCM instead of AES-256 options, if supported.
- Use a split-tunnel approach when possible. Route only critical traffic through the VPN to preserve local network speed for streaming, gaming, and other bandwidth-heavy tasks.
- Keep firmware updated. EdgeOS updates often include security fixes and performance improvements that can impact VPN stability and throughput.
- Optimize MTU and fragmentation. Start with a typical 1500 MTU, then adjust downward if you see VPN fragmentation, which can cause packet loss and slower connections.
- Consider a secondary device for VPN-heavy workloads. If you’re running a small home lab and you routinely push large VPN traffic, an inexpensive dedicated VPN gateway or a more powerful router can be a smart upgrade.
- Use reliable DNS. If you use your VPN for privacy, ensure DNS queries are covered by your VPN provider or your own DNS server to avoid leaks.
- Logging and monitoring. Keep an eye on VPN login attempts, unusual patterns, and interface statistics to catch misconfigurations early.
Security best practices
- Keep EdgeOS up to date with vendor patches.
- Use strong authentication on the management interface. prefer SSH keys or app-based auth over password authentication.
- Regularly rotate VPN certificates and keys, and disable any unused VPN endpoints.
- Use TLS-auth ta.key for OpenVPN to reduce certain types of attacks.
- Limit VPN access by IP, and implement two-factor authentication where possible for remote management access.
- Enable automatic backups of your EdgeRouter X configuration and store them securely.
Troubleshooting quick-start
- VPN won’t start: Check the logs for TLS handshake errors or certificate issues. Verify that certificates are valid and not expired.
- Clients can’t reach the internet after connecting: Ensure NAT and firewall rules are correct, and confirm the VPN tunnel is up and routing traffic properly.
- High latency or dropped packets: Verify MTU settings, try lowering the VPN’s encryption strength, or reduce the number of simultaneously connected clients.
- DNS resolution problems: Confirm the DNS server you push to clients, or set a reliable public DNS in the VPN config.
- VPN only works on one device: Check client-specific routing and ensure multiple client profiles if needed are correctly created and pushed.
Alternatives and upgrade considerations
- If you consistently hit performance limits on EdgeRouter X, consider upgrading to a more capable edge device with a stronger CPU and more RAM. Options include higher-end EdgeRouter models or dedicated VPN gateways.
- If you’re curious about WireGuard for faster performance, be prepared for compatibility questions. WireGuard isn’t universally supported on older EdgeOS builds, and you may need to explore newer hardware or alternative setups e.g., a small, dedicated device running WireGuard that your ER-X routes through.
