        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 ?

                    but the host 10.0.0.4 does not respond to pings
                    --- correct
                    Can host 192.168.62.181 ping 10.0.0.7 ?
                    --- I tried again and the answer is no
                    If you run ping 10.0.0.4 ->192.168.62.181

                          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

                                Ping 192.168.62.181->10.0.0.4 continues to fail
                                ping 192.168.62.181 -> 10.0.0.1 also fails.

                                does this have something to do with that the client is an azure virtual machine and has no lan interface, just a wan interface?

                                  NAT OUTBOUND changes the sender address (192.168.62.181) to its network address in the WAN interface (10.0.0.7) .the capture and package should show this
                                  for example
                                  IP 10.0.0.7 > 10.0.0.4: ICMP echo request, id 1, seq 16028, length 40
                                  IP 10.0.0.7 > 10.0.0.4: ICMP echo request, id 1, seq 16029, length 40

                                      192.168.62.181 -> 10.0.0.7 (nat outbound) -> 10.0.0.4 ->10.0.0.7 -> 192.168.62.181

                                      In packet capture you should see instead of 192.168.62.181 10.0.0.7 (client side , wan interface)

                                            I have to stop now, sorry,
                                            I want to thank you much for you time.

                                            we are missing something simple.
                                            As far as I can tell, all the settings are correct on the sever and client.

                                            I still think there is some issue with the fact the the client is in azure cloud and there is not lan interface, just a wan of 10.0.0.0/24.
                                            good night,
