      Is the LAN network on the client also 192.168.0.0/24?

            @Derelict yes I believe so If I follow you correctly the client LAN is 192.168.0.1/24

              @viragomann interesting is the static routes table is blank. Could it be that there needs to be at least one entry there for the VPN to- work properly?

                The clients LAN must not overlap the remote LAN, least of all it can be the same subnet. If so it's not possible to access the remote site.

                I've never seen an empty routing table on a device which has internet access. There must be at least one gateway and one route.
                When a OpenVPN connection is established and a route is pushed by the server to its LAN network, you should see this route pointing to the servers IP, probably 10.0.8.1, as you mentioned above you can access pfSense by that IP.

                  @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!

                            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.

                              @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

                                    Just to indicate my gratitude to everyone who has offered advice in this thread - thank you! (I am not yet connected to internal LAN however)

                                      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
