      I have created a new opveVPN.

      My IPv4 Tunnel Network is 10.10.70.0/24
      My IPv4 Local network(s) is 10.10.10.0/24

      I can connect and access pfsense gui with 10.10.70.1.
      I have
      This is my local route table (my remote PC from whom I connect to the VPN)

      I am unable to ping or connect any 10.10.10.X IP.
      If I grant any of my servers 10.10.70.X IP I am able to SSH or RDP into it.
      I am able to ping 10.10.10.X connections from my pfsense machine.

      What am I missing?
      Why can't I route to 10.10.10.X

        @diana_shik In your OpenVPN server config, did you specify your 10.10.10.0/24 network under IPv4 Local network(s)?

            @diana_shik Do you have the client end set to not pull routes?

              @kom Not to my knowledge.
              I have created the client export via "Client Export Utility".
              I did not create any other client.

                After switching to IPv4 Local network(s) in tunnel settings to 10.10.10.1/16 my route table looks like this:

                I have now:

                        10.10.0.0      255.255.0.0       10.10.70.1       10.10.70.2    281

                If I run tracert 10.10.10.2 I get:

                Tracing route to 10.10.10.2 over a maximum of 30 hops

                1 23 ms 23 ms 30 ms 10.10.70.1
                2 * * * Request timed out.
                3 * * * Request timed out.

                So now I am routed to the tunnel but still can't access the LAN.

                  @diana_shik Does your OpenVPN tab have any rules? It should have an Allow All rule created by the wizard but best to double-check.

                    @kom Yes, it have an allow all.
                    Also there is an inbound pass to openvpn port on the WAN.

                        First thing to ask, is pfSense the default gateway in the remote network?

                          Also I am able to pint and trace this IP from pfsense LAN intarface.

                            Okay, so check the following, please:
                            On pfSense go to Diagnostic > Ping
                            Do a ping to a machine you want to reach from VPN. Should work, I assume.
                            Then change the source to OpenVPN and try again.

                            If you don't get a respond you have to check the destination device. Maybe its firewall is blocking the access.

                              @viragomann What do you mean by "Do a ping to a machine you want to reach from VPN"

                              Under Diagnostics-> Ping I don't have VPN.
                              Should I?

                              I do have my openVPN and I loose all packets.

                                You should find your OpenVPN server in the drop-town.
                                You can simultanously do a sniff the packets on the LAN interface to see what's going on.

                                If you see the request packets on the LAN, but no responses, the destination machine either blocks the access from other networks by its own firewall or it has a different default route.
                                You may disable the firewall on the device for testing.

                                  @viragomann I see.

                                  I can ping and route from LAN successfully.
                                  I can not ping or route from openVPN.
