      cant ping a thing! All looks normal but can't ping either end. I checked and there's nothing blocked on the firewall.

        Mine is setup the opposite of yours, 1.2.3 is the server and 2.0 is the client.  I'll reverse it and see if I can reproduce your issue within the next couple of days on some downtime.

          Ok, reversed my setup (I said on some downtime but I'm an impatient person)

          Tunnel is up and running and I'm able to ping and access WebGUI on opposite LAN.

          Only thing I see that is different from your pics is that on the Server configuration, I entered my LAN IP CIDR in the Tunnel Settings/Local Network.

          You have on your client the remote network setup as 192.168.221.0/24 so enter that CIDR into the Local Network box on the Server.

          Remember to make a WAN tab firewall rule on your server allowing

          UDP    (Client Side WAN IP)    *    WAN Address    1195    *    none

          Once you have everything setup, go back to your client configuration and hit save to reinitialize the connection.  Should be proper after this.

            Hi Onhel,

            I didi the change and now i get a different log result but still no link.

            So here's my current settings:

            Server PFSense 2.0

            Server Mode: Peer to Peer (Shared Key)
            Protocol: UDP
            Device Mode: Tun
            Interface: WAN
            Local Port: 1195
            Shared Key: Openvpn key
            Encryption Algorithm BF-CBC (128 bit)
            Hardware Crypto: No Hardware Crypto
            Tunnel Network: 192.168.90.0/24
            Local Network: 192.168.221.0/24
            Remote Network: 192.168.0.0/24

            Client PFSense 1.2.3

            Protocol: UPD
            Server address: PFsense 2 WAN address
            Server Port: 1195
            Interface IP: 192.168.91.0/24
            Remote Network: 192.168.221.0/24
            Cryptography BF-CBC(128 bit)
            Authentication Method: Shared key
            Shared Key: Openvpn key

            And here's my current log result after adding the CIDR on the server:

              Ok, i updated the router with a new release for the 2.0 RC that came out this weekend and after reboot this is what a i get for log:

              Apr 5 20:47:53 openvpn[22853]: UDPv4 link local (bound): [AF_INET]174.113.135.15:1195

              All seems ok, no packages blocked but still no talk  :(

                You have a configuration missmatch between the two sites.
                (Look at the warning about inconsistent ifconfig)

                We do what we must, because we can.

                  You still have the Tunnel Network on the Server and the Interface IP on the client with different network CIDR.  They should both be 192.168.90.0/24 or both be 192.168.91.0/24

                  Server
                  Tunnel Network 192.168.90.0/24

                  Client
                  Interface IP 192.168.90.0/24

                  They have to match

                    I forgot about it, i deleted and re-created all and forgot that you mentioned this before.

                    I did the change and rebooted both routers. Still no luck.

                    Here's now my current log:

                    Apr 6 02:30:11 openvpn[45744]: Inactivity timeout (–ping-restart), restarting

                    I checked under "Status: OpenVPN" and found the following:

                    Client connections for OpenVPN to Plextec UDP:1195
                    Status data is not available for shared key servers.

                      Looks good, please post your firewall rules from server and client to rule out any other issues bc your config should be fine now.

                      I assume your two valid lans are

                      192.168.0.0/24
                      192.168.221.0/24

                        yes those are the subnets.

                        here are the firewall rules on the server. I checked both client and server and couldn't find any blocking for any of the web ips

                        thanks!

                          Enable logging on that WAN rule on the SERVER that allows port 1195, hit save on the CLIENT config page to reinitialize the connection.

                          Then go to the System Logs/Firewall Tab on the SERVER and look for that pass entry, just verify it is being passed.
                          Also on the Server, go to Diagnostics/States, enter 1195 in the Filter Expression and verify a state does exist for your OVPN.

                          I'm grabbing at straws here now and just trying to verify where this is failing because technically you should be up and running.

                          Another suggestion:

                          On the CLIENT config:
                          Check the Dynamic Sourceport Button and Check the Infinitely Resolve Server button.

                            hi onhel,

                            i know, it all should be working now, i mean is not rocket science :P

                            here's the screen shot of the diagnostic and on the firewall, after enable login i could only find one package pass
