      The routes on the client seem to be fine.

      Does each user login with a different user name and also certificate if the server is running in SSL/TLS mode?

      What does the server log show when a second client is connecting?

        Yeah, that's what is weird. Different user names. Client log shows it connects just fine and gets DHCP. I feel like it's a routing issue of some sort, but everything looks setup correctly.

          Sounds stupid, but on my LAN interface, it's setup as 192.168.1.1/24. I'm not limiting myself at all am I ? That's just configuring the IP of the pfSense box, right?

            For troubleshooting try to ping the LAN address 192.168.1.1.
            This should work at least if the client routes are set correctly.
            Then try to ping a LAN device.

                    I posted the IPv4 routing table above earlier, and you stated that it looked fine?

                    Here is the server1.conf files:

                      A couple things I see:

                      • The tunnel network is being pushed out to your clients as a route to a remote network, which is incorrect. Remove "192.168.2.0/24" from the IPv4 Local network(s) line.
                      • Considering this is a routed, split-tunnel deployment, why push public DNS servers?

                      Another thing to watch out for is... in a routed solution, the LAN subnets have to be unique across both ends. So, in your situation, any client that's connecting from a LAN subnet of either 192.168.1.0/24 or 192.168.2.0/24 will break the routing to the tunnel.

                      On the server-side, ideally, you will want to move away from popular subnets used by common SOHO routers (192.168.1.0/24, 192.168.2.0/24, etc) on both the LAN and the tunnel network.

                          @marvosa Thanks. I removed the DNS and removed the 192.168.2.0/24 from local network line. Connected again just fine on the client, but still can't connect to anything. The network I'm on right now is using a 10.x.x.x scheme. I'm pulling my hair out trying to figure out wtf the problem is.

                            Post new screenshots of both the client's routing table when connected and PFsense.
