Hello,
I'm using ProtonVPN on my opensense with Wireguard and a tired gateway group for fallback. Unfortunately ProtonVPN seems to require the same interface and gateway ip for each server. I followed a tutorial (link in the bottom) that suggested to have "fake ips" and than map them back with 1:1 NAT rules. This actually works.
Now I really would like to enable IPv6 support for the tunnels. This works well for one tunnel, but if I try to do the same trick I did for IPv4 the second tunnel still has a packet loss of 100%. Can I somehow get this to work?
Thanks
