      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 ?

                  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

                                      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)
