Proton VPN IPv6 Manual Setup

Update 2026-03-07: Proton has added the IPv6 configurations mentioned below to the WireGuard config files that you can get through the web dashboard. The guide below is for historical purposes only.

Over 80% of the servers support IPv6 but only the Linux & Android apps and the browser extension support it **at the moment**.
The Linux app supports IPv6 over the VPN but still connects to the VPN server using IPv4.

It's possible to make changes to the WireGuard configs that you can get from https://account.protonvpn.com/downloads to enable IPv6.

	#!/bin/bash

	# Detect tethering interface name on the phone (rndis0 or usb0)

	intf_cmd=$(adb shell "su -c 'if [ -e \"/sys/class/net/usb0\" ]; then echo \"Tethering interface: usb0\"; elif [ -e \"/sys/class/net/rndis0\" ]; then echo \"Tethering interface: rndis0\"; else echo "Unable to find tethering interface."; fi'")

	if [ "$intf_cmd" == "Tethering interface: usb0" ]
	then
	echo "$intf_cmd"
	intf="usb0"
