      No that's the server side for an SSL/TLS site to site which is what you have.

      Is the client end here also pfSense?

          So how is it routing traffic from the subnet behind it? You enabled some software routing on the 'computer'?

            @stephenw10 I don't understand the question sorry, I'm on a computer on the pfsense local network and that's why I can access it, to test I disconnect from the company's LAN network, connect from my cell phone data and do the tests connected to openvpn, if it is What you wanted to know from the question, I ended up not understanding.

              You said you need to be able to access the VPN clients from LAN is that not true?

                @stephenw10 exactly, this is what I need, I need my local LAN to talk to the Clients of my OPENVPN server

                  OK so you are testing by pinging from, for example, 192.168.140.57 to 50.50.50.5 ?

                  In that case the client at 50.50.50.5 must allow the ping traffic. For example Windows firewall will block that.

                    @stephenw10 Exactly, but for example, it's not just ping that doesn't allow it, I try to access my folders, and also transfer something, and my Windows firewall has been dead for ages, completely disabled.

                      Right but we just use ping as a test because it will usually be allowed.

                      So what error does it return?

                          OK, run the ping from a host on LAN then check the state table. Filter by the target IP address and make sure you see the states present.

                          You should see one state on LAN and one on OpenVPN.

                              So no states created on any interface?

                              Was the ping running while you checked the states? The states will close quickly after the ping stops, like maybe 30s.

                                  Hmm, then check the firewall logs. Is that blocked on LAN?

                                  If not check the routing table on the LAN client running the ping. Is it somehow trying to ping directly? Like maybe is still has a VPN connection active and isn't even trying to use the LAN?

                                    @stephenw10 Nothing appears in the logs when I try to ping.
                                    It's not possible that this is something that abnormal, I don't even make settings other than what comes by default in PFSENSE

                                      If the LAN host is pinging something in the 50.50.50.X subnet and it is using pfSense as it's default gateway that traffic will arrive at the LAN interface. So it will either be blocked or passed and open a state.

                                      Try running a packet capture on the LAN filtered by the target IP (50.50.50.X) and then running the ping from the LAN host. If those pings don't arrive at the LAN then there is some routing issue on the LAN host.

                                          OK so no ICMP packets at all there. But those were all inside 0.2 seconds so maybe it wasn't running long enough?

                                          What IP address on LAN were you pinging from?

                                          What we can see there though is that OpenVPN clients are able to connect to hosts on the LAN and they are able to reply. And importantly that there is no NAT. The OpenVPN tunnel IPs appear directly on the LAN.

                                            @stephenw10 This test I showed you is from the packet capture of PFSENSE itself for the IP that my clientOPENVPN is getting 50.50.50.2
