Hello,
I am trying to set up a site to site VPN connection via Wireguard.
Site A is a remote VLAN, where OPNsense has been installed to a VM.
Site B is my home network. There is a router (fritzbox) and behind the router there is a server, wheren OPNsense is installed.
I followed the config and searched many forums but couldn't solve me issues, so far.
I can establish a connection and a handshake is made. But I cannot access the LANs on the other site.
I have set the allowed IPs as decribed and all the firewall rules on both sites. Also have I setup a route on the home router pointing to te remote LAN, of course. Firewall shows me that traffic comes to the other end of the tunnel to the other OPNsense but it seems as if OPNsense would not know what to do with it, in both directions.
I am clueless.
By the way: OpenVPN between does two sites works fine. So this should really be something wireguard specific or something I missed at the home router.
Forget about. It works now. I played around a bit. The last change was removing the 0.0.0.0/0 from the peer on the server while leaving the other adresses. But I don't know if it was that what fixed it.
Unfortunately, after a reboot a few days ago, it does no work, anymore. I hadn't changed anything. I have checked almost any setting several times an have no idea what is wrong.
A road warrior can access the remote LAN but site to site does not work. Traffic obviously does not reach the remote OPNsense. When I tracert, it goes from the Fritzbox router to the local OPNsense, back to the router and back to the OPNsense and so forth. On Fritzbox I have set the route 192.168.133.0 255.255.255.0 192.168.132.33 (where 192.168.133.0 is my remote LAN and 102.168.132.33 is my local OPNsense). Can we confirm that this route on Fritzbox is correct and the only one needed there?
