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.

    Haha, yeah that’s what ProtonVPN support recommended to me and I am not sure if I want to disable IPv6 globally like that. I feel (with my inexperienced brain) that there’s gotta be a way to do it on a per connection basis.

      Maybe try forcing only IPv4 connections for the traffic you want to keep private?

      Your biggest leak maybe IPv6 DNS which is probably not that big of a deal really…
