OpenVPN Routing issue
-
Unable to get OpenVPN working, I suspect some routing issue. Any help would be appreciated.
Currently using the Pfsense openvpn site-to-site configuration from the documentation. The server site is using Pfsense CE 2.9.0 the office site is using Pfsense+ 26.07.
We are able to create a tunnel, but when either side tries to ping the other side, we receive no response.
We have verified the firewall rules and they are the same on both servers. They permit openvpn on the wan for port 1194. We have on both servers set the opt1 and openvpn rules to allow all to all with the destination being the "WAN address" setting.
We have set on the CE server in the Client Specific Override an entry as described in the documentation.
When we start OpenVPN the tunnel is created, and we see minimal traffic between both.
When we check, we see the routes are being added to the routing table.
But the issue is no connectivity from one site to the other.

Found the issue. It was related to the certificates and certificate authority. We recreated the authority certificate and then the server certificate and then the user certificate and used the new certificates, and everything started working.
