Wireguard site-to-site problem

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.

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