Assigning an interface for WireGuard Site2Site connection not possible?

[philipb232]

I'm wondering why I can assign an interface to a RoadWarrior setup and manage firewall rules via this interface, but this doesn't seem to work with a Site2Site connection? I can assign an interface, but then the tunnel doesn't even cum up anymore.

It is possible, I have 2 s2s and 1 road warrior instance running, 3 interfaces total.

So more details, please.

Rule of thumb:

You need to set the Instances with unique listening port.
If you create a new Instance and assign the same port as for the other Instance, it will not work.


And as requested by Patrick already, provide more details.
