S2S with Wireguard possible

my S2S-Network is running only when Wireguard is switched off at my main node.
Is it normal that it dosn’t work if Wireguard is running?

S2S is a WireGuard based service. It’s not possible to run WG Client/Server alongside of S2S on a stock setup, IIRC.

Yes,It is normal. S2S is a WireGuard based service too.

Thanks for the answears.

I try to change the vpn-rules, with mac- or ip-adress… but i don’t find the correct settings…
Is it possible only with the mac-adress?
Or where do i find the “correct” ip i need to connect s2s??
