      There's really not much else to it.  Good list of things to check here:

      DO NOT set a source address/port in a port forward or firewall rule unless you KNOW you need it!

        Do a packet capture on LAN just to confirm that the test packet is getting through, and any replies.

          What is the source of the traffic your blocking rfc1918 and bogon which could be blocking it before it gets to your nat allow rule.

          Does pfsense actually get a public IP on its wan?  You say modem, but most of the time when users say modem they really mean gateway that is doing nat.  If you have a nat in front of pfsense you need to make sure you forwarding that traffic you want pfsense to forward too pfsense in the first place.

            The attachment is a packet capture while using canyouseeme which could not see my service on port 51413.

            If I am understanding it the packet goes out and comes back in to my computer but yet canyouseeme says the port is closed?

            By modem I was referring to a Motorola cable modem and I don't think it is a problem because I mentioned I can bypass pfsense and connect my computer directly to this cable modem and it works as expected.

            Also, I have attached a Diagnostics > States.

              The traffic you're showing there is all outbound, initiated from your LAN.

              Sites like canyouseeme only test TCP ports and it looks like you're expecting UDP, which won't come back as open on such sites (can't test UDP in that manner).

                I am confused as to what to do.

                Can pfsense port forward and if so how do I do this?

                Is my WAN firewall listed  in Reply #6 on Sept. 22 correct?

                  Yeah. It works in 30 seconds for pretty much anyone but you. Click - click - click, done.

                    Thank you doktornotor for your support.

                    I am not sure what you're intent was but it certainly is not helpful to my problem.

                    Is someone willing to help me in a positive manor?

                    For example, doktornotor, you didn't answer if my WAN firewall rule is even correct or not?

                      Yes, your port forward/rule  looks correct.  That's why people keep pointing you here:

                      https://doc.pfsense.org/index.php/Port_Forward_Troubleshooting

                      Your problems is very likely something on that list.

                        Dude this really is click click!!  Run through the troubleshooter if your having issues - it covers pretty much every single scenario that there is issues.

                        Really is 30 seconds..  Have something listening..  My ubuntu vm is listening on ssh on 192.168.1.7

                        I create a foward, let it create your firewall rule - go to canyouseeme, unless your testing udp that you can not check like that.. Create your forward with tcp first to something listening, rdp, ssh, ftp, http, anything!!  On your box running the service do a netstat, do you see it listening (netstat works both linux and windows
