I finally managed to get my Wireguard setup to work in both ways! Beforehand I could ping from A to B, but not the other way around.

A network
B network
(both actually use multiple /24 subnets, but I reserve a /16 for each site for the sake of simplicity)

Lots of fiddling later this is my configuration:
A interface
A allowedIPs
B interface
B allowed IPs

ping from to => 172ms
ping from to => 172ms

it works, yay! now to add more sites...

    WoW my setup was not that complicated but it was also not easy 🙈

    @hamburghammer It is actually quite easy once you wrap your head around the way the InterfaceIP and AllowedIP parameters work..
