      @viragomann again my apologies - my local LAN is 192.168.1.1/24; the LAN I am trying to remote into is 192.168.0.1/24

        this is the default gateway and the Static Routes table is again blank

          The routing table is the key here, but that one of the client!

            @viragomann How do I display the client routing table or which one do you need to see?

                The first step to configuring a VPN is understanding what it is you are actually doing.

                On the client, connect the VPN. Then print the routing table.

                Some common command lines:

                Windows: route print
                Mac: netstat -rnfinet
                Linux: netstat -rn4

                You can use Diagnostics > Routes in the pfSense software.

                DO NOT set a source address/port in a port forward or firewall rule unless you KNOW you need it!

                  @rwhitney said in Very Confusing is OpenVPN Setup:

                  I have set the route LAN network to 192.168.0.1/24

                  That should be 192.168.0.0/24 in the local subnets field. Unless you have set Redirect IPv4 Gateway in which case that should be not set anywhere as everything is routed.

                      @stephenw10 setting it to 192.168.0.0/24 does not seem to make a difference - I did have it set to Redirect IPv4 Gateway, but have removed that

                          It's still sending route all and not just 192.168.0.0/24.

                          Try restarting the server end to be sure that new setting in place and then check the Windows client routing table.

                            @stephenw10 so reboot the netgate server? I will have to wait a couple of hours first

                              No. Restart the OpenVPN process. (Status > Services, stop it and start it. This is restarted when you make a change like disabling the redirect gateway push but Steve is just being thorough.)

                                @Derelict I just restarted the running process for openvpn. I did just notice that I am getting a connection error: key registration failed to occur within 60 seconds... I am trying this from a Windows laptop at work through an external wirelass network. I don't have this connectivity problem from home on my linux box - just from there I still cannot see the local LAN here at work. All I can see is the firewall

                                    That was wrong. It should be "Local Networks".
                                    I'll correct it above.

                                          If I were to start from scratch, what would be the first thing to do? (setup the Cert?)
                                          second: setup an openvpn server: (I think I have this set).
                                          Third: setup a user?
                                          Fourth: setup a user cert?
                                          Fifth: download config from Client Export
                                          What am I missing?

                                            Your setup looks well, however starting from scratch with the OpenVPN part may help making it work.

                                            The cert should not be wrong as long as you've generated the correct type (CA, server, client).

                                            Apart from this, I start with the certs:
                                            CA
                                            server
                                            client(s)

                                            Then I set up the server and at last I export the config and install it on the client computer.
