      Consider that the destination device can block access from the remote or from outside in general by its own firewall.

      For further investigation post the routing tables of both nodes.

                Cannot find any matching VPN tunnel here.
                On the server you have 172.16.12.0/24.
                And on the client 10.0.0.2.

                  @viragomann that 172.16 is my personal vpn from my laptop to the server, not the site to site, i checked the site to side is both set to 10.0.0.1/30 on both sides

                    But it is not shown up on the server. So there might be something wrong in the settings.

                        @kr0490 I checked and can’t find a misconfiguration with ips. Do I need to create some kind of routing entry?

                          @kr0490 by adding an interface i now see the proper route tables showing, below is an example from the server. But still cannot ping or access things on the opposite network.

                            @kr0490 got it working, added interface on both for open vpn, and then added some firewall rules, now it’s all good! Thanks for all the help!
