Trying to setup site to site between two windows servers

[mkono87]

I have been using wireguard for a while in a remote server config with a few client endpoints but this time I trying to set up a site to site with just two windows servers communicating with each other and I can seem to figure out why i cant ping each other.

Site B server is sitting on LAN but on Site A I have it in another VLAN(Homelab). I blocked all homelab traffic to LAN except the windows server. (This doesnt really matter in this case)

I noticed yesterday if I try to ping from Site A to B I cant ping. But....if I started to ping from B to A it responds and I can then ping from A to B. Today doesnt seem like any reponse is happening. I tracert on each system but they dont make it past the firewall.

Don't allow it to the LAN, allow it to the WG.
And make sure you add it to allowed networks on the other end.

That LAN rule is for the remote clients that are already setup using wireguard. Figured it would use the same rule to pipe the traffic through.

Edit: Oh you mean on the Homelab interface? Sorry, that allow to LAN rule is non related to this wireguard setup. But I will try that.

Allowed network where? in the endpoint or a firewall rule?

In the endpoint.
