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.

Thanks! This works, but only if I use wg-quick. If I import the connection into KDE's NetworkManager it doesn't. I am assuming its because it isn't running the PreDown and PostUp commands.

Hmm, I found that https://feeding.cloud.geek.nz/posts/using-iptables-with-network-manager/

But it seems to be fairly complex and you would even have to change the script to only handle the WG device.
