What Proton VPN on EdgeRouter is and isn’t
Proton VPN on EdgeRouter is essentially using the EdgeOS OpenVPN client to connect to Proton VPN servers. EdgeRouter devices from Ubiquiti are powerful enough to run an OpenVPN client, route all traffic from your LAN through the VPN tunnel, and still provide your usual network features like DHCP, NAT, firewall rules, and port-forwarding. This setup doesn’t require running a separate computer or a Raspberry Pi as a VPN gateway. instead, the EdgeRouter becomes the VPN gateway for your entire home network.
A quick note on limitations: EdgeRouter devices don’t come with WireGuard built in in all firmware versions, and Proton VPN’s straightforward router guides often emphasize OpenVPN for broader compatibility with consumer router firmware. If your EdgeRouter firmware supports WireGuard in a future update, you can explore that path, but for now this guide centers on OpenVPN for maximum reliability with Proton VPN on EdgeRouter.
Why EdgeRouter users should consider Proton VPN
- Privacy and security at the router level: encrypts all traffic from connected devices without needing individual VPN apps.
- Device compatibility: any device on your network benefits from VPN protection without needing extra configuration.
- Fine-grained routing: you can route only specific devices or subnets through the VPN, or shield the entire network.
- Proton VPN features: strong focus on privacy, with no-logs philosophy, DNS leak protection, and a range of servers across multiple regions.
Prerequisites and planning
Before you start, make sure you have:
- An EdgeRouter any model that runs EdgeOS with firmware up to date
- A Proton VPN Plus or Visionary plan or a plan that supports OpenVPN on routers
- An active Proton VPN account and access to OpenVPN configuration files
- A computer and network access to the EdgeRouter’s GUI or SSH CLI
- Basic familiarity with EdgeOS command-line interface CLI or the ability to follow step-by-step commands
Why OpenVPN instead of WireGuard on EdgeRouter right now
- OpenVPN has broad compatibility with EdgeOS out of the box.
- Proton VPN provides OpenVPN configuration files suitable for Linux-based routers, making it easier to port to EdgeRouter.
- WireGuard support on consumer routers can be more complex and EdgeRouter’s current GUI options for WireGuard are less universal across firmware versions, so starting with OpenVPN gives you a stable baseline.
Step-by-step OpenVPN setup for Proton VPN on EdgeRouter
Note: Replace placeholders with your actual Proton VPN server choice and configuration files. The exact file locations may vary depending on how you transfer files to your EdgeRouter.
- Gather Proton VPN OpenVPN configuration files
- Log in to Proton VPN.
- Navigate to the download/openvpn section and download the OpenVPN configuration package for the server you want to use choose a server that fits your location and speed needs.
- You’ll typically receive a .ovpn file along with CA certificate, TLS auth key, and possibly user authentication data.
- Prepare your EdgeRouter for OpenVPN
- Access your EdgeRouter via SSH or the GUI.
- Ensure you have a directory for VPN config files, e.g., /config/auth/protonvpn/
- Upload your .ovpn file and related certs/keys to that directory. You can use SCP or a file transfer method you prefer.
- Create a new OpenVPN interface on EdgeRouter
- Enter configuration mode:
configure - Create the VPN interface and point it to your OpenVPN config:
set interfaces openvpn vtun0 mode ‘client’
set interfaces openvpn vtun0 config-file /config/auth/protonvpn/yourserver.ovpn - If Proton’s config relies on a separate CA certificate or TLS key, place those files in the same directory and reference them in the config:
set interfaces openvpn vtun0 ca-cert-file /config/auth/protonvpn/ca.crt
set interfaces openvpn vtun0 tls-auth-key /config/auth/protonvpn/ta.key
- Configure VPN detailing and IP addressing
- Assign VPN tunnel IPs these should align with the OpenVPN server’s configuration, usually 10.8.0.0/24:
set interfaces openvpn vtun0 local-address ‘10.8.0.2’
set interfaces openvpn vtun0 remote-address ‘10.8.0.1’ - If the server requires a specific port or protocol UDP/1194, make sure the config-file handles that, or specify it via:
set interfaces openvpn vtun0 protocol ‘udp’
set interfaces openvpn vtun0 remote-port ‘1194’
- Define routing so your LAN traffic goes through the VPN
- Route default traffic 0.0.0.0/0 through the VPN tunnel:
set protocols static-route 0.0.0.0/0 next-hop 10.8.0.1 - If you want only a subset of devices to use the VPN, set up policy-based routing by VLANs or source IP subnets and route those through the VPN VTUN:
set protocols static-route 192.168.2.0/24 next-hop 10.8.0.1 - Ensure your LAN interface is properly assigned. If your LAN is on eth1 example, you might have:
set interfaces ethernet eth1 family inet address 192.168.1.1/24
- DNS configuration for VPN privacy
- Point DNS to Proton VPN’s DNS servers or use a private DNS that is not leaking your real IP:
set service dns forwarding systemd-resolved false
set system name-server 1.1.1.1
set system name-server 9.9.9.9 - Enable DNS leak protection by ensuring all DNS requests go through the VPN tunnel:
- If your EdgeRouter supports this, route DNS queries via the VPN interface vtun0
- Firewall rules and NAT
- Ensure VPN traffic is allowed by your firewall:
set firewall name VPN-IN default-action accept
set firewall name VPN-LOCAL default-action accept - NAT rules for internet access through VPN:
set nat source rule 100 outbound-interface vtun0
set nat source rule 100 source address 192.168.1.0/24
set nat source rule 100 translation address masquerade - If you want to exclude specific LAN devices from the VPN, configure exceptions accordingly.
- Commit and test
- Save and apply:
commit
save - Bring up the VPN interface if it isn’t already running:
run show interfaces openvpn - Test the VPN is working by checking the public IP from a connected device:
- Visit a site like whatismyip.com from a device on your LAN and confirm the IP shows Proton VPN’s server location, not your home ISP.
- Kill switch and leak protection
- A router-wide kill switch ensures that if the VPN drops, traffic doesn’t leak to your ISP. If EdgeRouter gear allows, implement a firewall rule that blocks traffic from LAN to WAN unless the VPN interface vtun0 is up.
- Example concept adjust to your firewall naming:
- If VPN is down, block 0.0.0.0/0 traffic from LAN to WAN
- Permit traffic only when vtun0 is up
- Monitoring and maintenance
- Regularly check the VPN interface status:
- EdgeRouter CLI: show interfaces openvpn
- If the VPN disconnects, verify the server status and the ovpn file. Keep a backup of the config and re-upload if Proton VPN changes their server endpoints.
- Schedule periodic reboots or health checks if your EdgeRouter is exposed to frequent power outages, ensuring VPN reconnects cleanly on startup.
DNS handling, kill switch, and traffic routing in practice
- DNS leaks happen when your devices resolve domains via your ISP’s DNS servers while the tunnel is up. Keep DNS resolution on the VPN side or via VPN-provided DNS servers and test for leaks with online DNS test tools.
- The kill switch concept on a home router isn’t perfect out-of-the-box on all EdgeRouter setups, but you can approximate it with firewall rules that block traffic if the VPN is down. This keeps you safe if the VPN connection drops momentarily.
- For routing, decide if you want all traffic LAN-wide or only specific subnets to ride the VPN. A common approach is to route the entire 192.168.1.0/24 network through vtun0 to protect every device. For visitors or IoT devices, you may want to exclude some devices from VPN to preserve performance.
Performance expectations and optimization tips
- VPN overhead is a real thing. Expect some speed loss due to encryption, server distance, and the VPN protocol. OpenVPN on UDP generally gives a good balance of speed and reliability, while WireGuard can be faster but may require more careful device support and server compatibility.
- Server location matters. Choose Proton VPN servers physically closer to you for lower latency. If you’re in North America, a server in your country or a nearby region typically provides better speeds than a far-away location.
- CPU and hardware matter. EdgeRouter models with more powerful CPUs will handle encryption work with less impact on throughput. If you notice slowdowns, consider switching to a closer server, reducing encryption overhead by using a lighter cipher when available, or upgrading to a router with better processing power.
- DNS performance can affect perceived speed. Use fast, private DNS servers like Cloudflare 1.1.1.1 or Quad9 9.9.9.9 and ensure DNS requests route through the VPN.
Security considerations
- Use Proton VPN features like automatic kill switch if available in the Proton config you adapt to EdgeRouter and DNS leak protection to minimize exposure.
- Regularly update EdgeRouter firmware to mitigate vulnerabilities in EdgeOS.
- Keep Proton VPN configuration files secure and rotate credentials per Proton VPN recommendations if you reconfigure servers or credentials.
- Remember that router-level VPN protects devices on your network, but you should also practice safe browsing habits and keep devices themselves secure with up-to-date software.
Troubleshooting basics
- VPN won’t start: re-upload the ovpn config, verify credentials, check that the OpenVPN service sees the correct server address and port, and verify that the vtun0 interface exists.
- DNS leaks: verify that DNS queries are not being sent outside the VPN. Adjust DNS settings to point to VPN-provided DNS or configured private DNS that is reachable only within the VPN.
- Slow speeds: try a different Proton VPN server, ideally in a nearby region. check your EdgeRouter CPU load. confirm you’re using UDP OpenVPN if your server supports it.
- IP not showing VPN location: ensure traffic is routed through the VPN interface default route via 10.8.0.1. Check for split-tunneling misconfigurations.
- VPN disconnects frequently: look for edgerouter log messages around OpenVPN and reconnect logic. you may need to adjust keepalive settings or reissue the VPN config.
Security and privacy considerations for home networks
- A router-level VPN is a strong privacy layer, but it won’t magically fix malware or phishing. Use endpoint security on devices as well.
- Consider enabling two-factor authentication for Proton VPN account to reduce the risk of credential leakage.
- Review Proton VPN’s privacy policy and logging practices to understand what data remains on Proton’s servers and what is anonymized.
Performance and real-world expectations
- If you’re streaming, gaming, or video conferencing, expect some latency changes due to VPN routing. Test different servers to find a balance between speed and privacy.
- In practice, most home users report 10-40% speed reductions depending on server distance and hardware. EdgeRouter’s hardware will influence this, with mid-range devices handling OpenVPN without major bottlenecks for typical home usage.
