      newbie question, on 10.0.0.7, the openvpn client, the outbound nat rule mode is automatic outbound nat rule generation and there is no option for adding rules, but I can add a mapping.
      should I add a mapping or do I need to change the outbound nat mode?

        Do not create a NAT OUTBOUND rule yet
        Try to do as I wrote in the previous post

        If I understand everything correctly, you will be able to ping 10.0.0.4 from a network 192.168.62.0 / 24 and Vice versa

            are you running a different version of pfsense, as your screenshot look visually different

              1. 10.0.0.7 already knows about this network
                0_1551046307753_1b7cad08-5ae7-4f73-80e1-cf16e971e152-image.png

              No need to create another static route on 10.0.0.7 for network 192.168.62.0 / 24
              Don't need to configure OUTBOUND NAT now
              Need to, for example

              1. on host 10.0.0.4, run the route add command ( see previous post)
              2. create allow rule (see previous post)

              Then you can ping the host 10.0.0.4 from the network 192.168.62.0/24
              and the host 10.0.0.4 will be able to ping the network 192.168.62.0/24

                  Hmmm.
                  Let's check.
                  I see that packets went in the direction 192.168.62.0/24
                  Check to see if the numbers appear in this place ?
                  This is a rule on the OpenVpn server interface

                  Can host 10.0.0.4 ping 192.168.62.1 ?
                  Can host 192.168.62.1 ping 10.0.0.4 ?

                      On the Openvpn server side
                      In WEBGUI
                      /Diagnostics/Packet Capture /
                      Interface Openvpn
                      Protocol ICMP
                      Start

                      what is the result ?

                          Now the same is on the Openvpn client side
                          WAN interface only
                          we continue to ping 192.168.62.181 > 10.0.0.4

                                We can see that the tunnel is working
                                but the host 10.0.0.4 does not respond to pings
                                Can host 192.168.62.181 ping 10.0.0.7 ?
                                If you run ping 10.0.0.4 ->192.168.62.181 (or 192.168.62.1)
                                What will packet capture show ?

                                        Host 10.0.0.4 not rebooted ?
                                        Check if there is a route to 192.168 in its routing table

                                            Good
                                            Let's try another way
                                            Ping 192.168.62.181->10.0.0.4 (or 10.0.0.1 or any other host from 10.0.0.0/24)
                                            on the client side
                                            Firewall/NAT Outbound/Edit (manual outbound)
                                            0_1551051478768_9c094fbe-a5dc-4d38-9a83-bb3c52a79253-image.png

                                            0_1551051457167_47e98eeb-0674-41e2-abbb-4de552166e83-image.png

                                            If everything is configured correctly, then in packet capture (client side) you will see
                                            10.0.0.7 ->10.0.0.4
                                            10.0.0.4 ->10.0.0.7
