      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.

                        So I did a ping to 8.8.4.4 from a device on d net and received the following for d net interface and didn't receive anything for wan.

                          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?

                                There are no alerts on the dashboard . when I do a packet capture for d net it works fine if i do the same way for wan I get nothing.

                                Also When I sort firewall logs for destination IP while running a continuous ping I get nothing.

                                  Hmm, mystery packets.....

                                  Either blocked with no logs or passed with no state... or something else between the pcap and the firewall. Hard to see what that might be though.

                                  About the only thing that would do that would be if you have the captive portal enabled on that interface. Is that possible?

                                    So I deleted the entire interface and recreated under opt2 different interface and it works fine now, strange.
