Inverted gateways on tunnel

[senseivita]

This is not the first time this happens but it's the first time I can't remember how to fix it. :( I've mixed and matched options, sometimes it works, but this time it seems

The addresses are assigned on the correct side, but the gateways aren't, not for IPv4 at least; so you can see it's clearly pinging itself if you compare it's RTT with the IPv6 traffic on the same tunnel, which was brought up fine.

The strangest thing is that it actually works but not for everything so I kinda have to fix it.

Thanks!
