Proton VPN edgerouter prerequisites and what you need to know
- EdgeRouter model and firmware: Ensure you’re on a recent EdgeOS firmware that supports OpenVPN as a client. If your device firmware is outdated, update it first.
- Proton VPN plan: OpenVPN access is available on Proton VPN, including the ability to pull OpenVPN configuration files for routers. You’ll typically choose a server/location, then download the OpenVPN config often as .ovpn files or use the manual config details.
- OpenVPN basics: You’ll need a Proton VPN account and credentials username/password if the server requires them. You’ll map those to the EdgeRouter’s OpenVPN client settings.
- Network plan: Decide your LAN subnet for example 192.168.1.0/24 and confirm your EdgeRouter’s WAN interface usually eth0 and LAN range usually eth1/eth2, depending on your model.
- DNS strategy: Decide whether you want Proton VPN DNS servers to handle name resolution or stick with your home DNS DNS leaks can happen. Proton’s DNS is a good choice for privacy.
Step-by-step setup guide: OpenVPN on EdgeRouter for Proton VPN
Step 1 — Get Proton VPN OpenVPN config and credentials
- Log in to your Proton VPN account.
- Go to the manual configuration section and choose OpenVPN.
- Select a server/location and download the OpenVPN config file .ovpn or copy the necessary details server address, port, protocol, CA certificate, and TLS/auth settings.
- If Proton VPN provides separate CA/client certificate materials, save those in a known location. You’ll use them on EdgeRouter.
Step 2 — Prepare EdgeRouter for VPN client use
- Connect to your EdgeRouter via a local network IP for example, 192.168.1.1 or via SSH.
- Back up your current config in case you need to revert.
- Decide whether you’ll configure the VPN using the EdgeRouter GUI Web UI or via the CLI. Both approaches work. GUI is typically easier for beginners.
Step 3 — Create the OpenVPN client interface GUI approach
- Open the EdgeRouter Web UI.
- Go to VPN > OpenVPN or the VPN section that exposes OpenVPN Client.
- Add a new OpenVPN client:
- Name: ProtonVPN_Client
- Server/Remote Address: enter the server address from your Proton config
- Port and Protocol: match the Proton VPN settings e.g., UDP 1194, or as provided
- Authentication: Username/Password enter your Proton VPN credentials
- TLS/CA: if Proton’s config uses a CA cert, upload it here. otherwise, you’ll rely on the embedded certs in the .ovpn data
- Client certs: leave blank unless Proton VPN provides separate client certs
- Advanced options: enable TLS auth or similar if your config requires it
- Save the OpenVPN client. The GUI should establish a tun0 or similar interface when the VPN connects.
Step 3 alternative — Create the OpenVPN client interface CLI approach
- If you prefer the command line, you’ll typically map the OpenVPN client to a tun interface e.g., tun0 and then bind it to your LAN NAT rules. The exact commands vary by firmware, but you’ll generally:
- Add a VPN client tunnel in OpenVPN mode
- Point the client to the Proton VPN server, port, and protocol
- Provide credentials username/password or a certificate bundle
- Attach the tun interface to your routing rules
Step 4 — Configure LAN routing and NAT so all traffic goes through the VPN
- Goal: all devices on your LAN use the VPN by default, with VPN as the outbound path.
- In the GUI, set the OpenVPN interface tun0 as the outbound interface for NAT rules:
- Create a NAT rule: source address should be your LAN e.g., 192.168.1.0/24
- Outbound interface: tun0
- Action: masquerade
- If you’re using CLI, you’ll create a NAT rule similar to:
- set service nat rule 1000 type masquerade
- set service nat rule 1000 outbound-interface tun0
- set service nat rule 1000 source address 192.168.1.0/24
- Ensure LAN devices get their IPs via DHCP from the EdgeRouter and that the VPN interface comes up before devices attempt to route.
Step 5 — DNS configuration to prevent leaks
- Choose Proton VPN’s DNS or your preferred secure DNS as the resolver for the VPN path.
- In GUI: point the VPN client to push or use a DNS server address e.g., 10.0.0.2 if Proton VPN provides one for your tunnel.
- In CLI: configure the VPN tunnel to use a DNS server within the EdgeRouter’s VPN interface or set a DNS override for traffic after the VPN is established.
Step 6 — Add a kill switch to prevent leaks if the VPN drops
- The kill switch ensures no traffic leaves your LAN when the VPN tunnel goes down.
- How to implement high level:
- Create a firewall rule that blocks all outbound traffic from the LAN unless the VPN interface tun0 is up.
- Implement a fallback so that if tun0 is down, traffic is dropped rather than routed to the regular internet interface.
- In GUI: set firewall rules for the LAN zone with a rule set that requires tun0 to be up for outbound traffic.
- In CLI: create a VPN-kill-switch rule set linked to the tun0 state, and apply it to the LAN outbound path.
Step 7 — Test your Proton VPN on EdgeRouter
- From a connected device, go to a site like whatismyipaddress.com and confirm the IP shows the VPN server location.
- Run a DNS leak test dnsleaktest.com or similar to ensure DNS requests aren’t leaking to your ISP.
- Check the VPN interface status on EdgeRouter: verify tun0 or the VPN interface name is up and has the expected internal IP.
- Reboot the EdgeRouter and ensure the VPN reconnects automatically and traffic resumes through the VPN.
Step 8 — Optional: multi-device strategies and performance tweaks
- If you want to keep a separate non-VPN LAN segment for certain devices, segment your network with VLANs and set VPN routing rules per VLAN.
- For performance: pick a Proton VPN server that’s geographically close to your location for lower latency—especially useful for gaming or streaming.
- Monitor VPN uptime and reconnect behavior. enable automatic reconnect on VPN drop if your EdgeRouter firmware supports it.
Step 9 — Troubleshooting quick tips
- If you don’t see the VPN tunnel come up: double-check the server address, port, and protocol in the Proton VPN config. verify credentials are correct.
- If NAT isn’t routing LAN traffic through the VPN: re-check the outbound-interface in your NAT rule and ensure the VPN interface is truly up before traffic attempts to route.
- If DNS leaks appear: ensure that all DNS requests are resolved through the VPN tunnel. consider forcing the EdgeRouter to use Proton DNS and not the ISP’s DNS.
- If you have IPv6 issues: disable IPv6 on LAN devices or adjust firewall rules to prevent IPv6 traffic from bypassing the VPN.
