      The client is receiving an address of 10.1.40.21 /24 and gateway of 10.1.40.254

        Ok that should be fine then.

        So set a continuous ping running to 4.2.2.2 then check the state table in Diag > States. Filter by 4.2.2.2.

        You should see a state on the new interface and a state with NAT on the WAN interface.

          Thanks Steve for your reply, I checked the states and filtered by 4.2.2.1, unfortunately it showed nothing. The firewall rule looks as below.

            Outbound NAT is configured for 10.1.40.0/24 ????

              it appears to be there. Is there another good way to look at the logs? NAT is auto generated.

                Try to run Packet Capture or tcpdump on the wan interface to see what's going on
                interface WAN
                Protocol ICMP
                Host 4.2.2.2

                Ideally , you should see this result

                21:09:16.501092 IP XXX.XXX.1.96 > 4.2.2.2: ICMP echo request, id 25266, seq 0, length 64
                21:09:16.556329 IP 4.2.2.2 > XXX.XXX.1.96: ICMP echo reply, id 25266, seq 0, length 64

                    If this is the wan interface, you can see that nat outbound does not work correctly
                    Try to use Manual Outbound NAT

                      If you're seeing packets come in but no states generated either on DEVICENET or WAN (you should see both) then something is blocking that traffic. Do you see it blocked in the firewall logs? Which rule is blocking it?
                      If not you may have something set to block without logging like maybe pfBlocker or Snort.

                          Are you using 8.8.8.8 as the monitoring IP for the WAN? Or pinging it from anywhere else?

                          Because those pings on DEVICENET are at ~5s internals but on WAN are at 1s intervals. I don't think that's the same traffic.

                          You were seeing no open states and they will be there is traffic is being passed.

                          Check the firewall logs.

                          Do you have any packages installed?

                            I had 2 separate computers. I just verified the traffic again.

                              Still 1s intervals on WAN and 5 internally. Use a different IP that isn't in use anywhere else.

                              Check the firewall logs.

                              Do you have any packages installed?

                                That interface doesn't even appear in the firewall logs.

                                Yes I have a few packages installed screenshot attached.

                                  Ok, none of those packages should be an issue.

                                  Did you filter the firewall logs by the IP you were trying to ping? Or by the interface you were pinging from?
                                  That screenshot shows 21s of logs so they moght just not be shown there.

                                  But, again, try pinging by some other IP that is not used anywhere else. Leave the ping running then check the state table and filter by the target IP. Leave the interfaces set to 'all'. You should see states on both the internal interface and WAN. You can verify that by testing from a working interface so you know what it should look like.

                                        Do you have any floating rules ?

                                        And what is Openvpn interface ?
                                        Is it a server or a client ?

                                            If you are seeing no states on any interface and no packets leaving WAN that traffic is being blocked.

                                            Run the ping again and check the firewall logs. Filter by destination IP 8.8.4.4. If you see logged blocks click the red X to see what rule is blocking it.

                                            Are you seeing any alerts reported on the dashboard?
