Hi!
I have made site-to-site between 2 routers on different wan locations. both have public IP.
The traffic is being seen on firewall rule from office 1, but no traffic from office 2? Wierd.
I use 0.0.0.0/0 for “allowed IP” from both sites, but I can’t ping och get connections to devices between the lans.(I use VLAN on both sites)
I have made routes to local ip and used the WG adress as gateway.
Is there a problem when using it with vlan?
no problems, 3 sites are connected via wireguard dual stack.
solved
The problem was the Public key had been changed by itself for some reason?!..edit them back and everything worked like a charm

Quick, get rid of your MT device, clearly its possessed by an evil spirit.

Be careful if you add any additional remote users to the config as then it will not necessarily work properly!!!
