While experimenting with ProtonVPN’s Wireguard configs, I realized that my real IPv6 address was leaking while IPv4 was correctly going through the tunnel. How do I prevent this from happening?

I’ve already tried adding ::/0 to the AllowedIPs option and IPv6 is listed as disabled in the NetworkManager profile.

    Yes, I agree - using a VPN that supports IPv6 is preferred. If they don’t want to/can’t change providers, then disabling IPv6 is the best way to prevent IPv6 leaks without negatively affecting network performance.
