        UDP is pretty difficult to get clear picture of open or not, unless something actually answers.. It can fairly often show in accurate results.

        If your sending UDP traffic - best to do is sniff on your pfsense wan while you send that traffic, etc.

          @cire3 You have quite a few ports open, your pfSense GUI is open to the internet.

          Nice purple background.

            Yeah your top rule that says ping is ANY to tcp... Pretty bad rule!

            bad.png

            This would be a proper rule to allow ping to your pfsense wan address

            You would want to use the alias - in case your wan IP changes at some point in the future.

              fixed imcp.PNG

              Rule removed, and thanks !

              I believe I was trying to allow ping on WAN.

              So do I have any way to determine my ports are working as they should ?

              I have no clue if this device is even setup correct and I'm just beating my head against the wall for nothing ?

                Well if the device uses 9300 UDP.. And you can send UDP on 9300 from outside your network.. Way to validate even if the device is not working on 9300 is sniff.

                Sniff on your wan - do you see the 9300 UDP being send to pfsense. Good!

                Sniff on the lan side interface where this IP your trying to forward sits.. Do you see the 9300 being sent on to this IP? If so good - pfsense is now out of the picture and doing what you told it to do.. If still not working something else going on, wrong IP your sending too, not listening on 9300 udp like you thought. Service not even running on this server, Firewall on this device, etc.

                edit: example using that site linked too

                Setup a port forward to one of my my machines 9300. Not listening on 9300 for anything.

                forward.png

                But I can tell working because I see it sent on to my machine on 9300, even though the machine didn't answer

                  If you have a mac on the internet ncat might help:-

                  andy@mac-pro ~ % ncat -z -n -v -u 198.0.115.21 9300
                  Ncat: Version 7.91 ( https://nmap.org/ncat )
                  Ncat: Connected to 198.0.115.21:9300.

                    @nogbadthebad Sorry, no Mac on site to take over :(

                    Ok, so packet capture LAN and this is what I have

                    Port 9300 :

                    11:57:55.826423 IP 212.129.21.56.36032 > 10.10.1.25.9300: UDP, length 0
                    11:57:55.827646 IP 10.10.1.25.9300 > 212.129.21.56.36032: UDP, length 14
                    11:57:55.839031 IP 185.209.161.169.38480 > 10.10.1.25.9300: UDP, length 0

                    I'm calling this good as it's hitting 10.10.1.25 Correct ?

                    Port : 24493 Coverts to 2728

                    12:01:32.723636 IP 88.119.179.10.43438 > 10.10.1.25.2728: tcp 0
                    12:01:32.736754 IP 185.86.77.126.58520 > 10.10.1.25.2728: tcp 0
                    12:01:32.738876 IP 185.83.213.25.55756 > 10.10.1.25.2728: tcp 0

                    So I see it on LAN hitting 10.10.1.25

                    Port : 44443 Converts to 443 And works as it should (We can access GUI)

                    So all I have left is port range.

                    Port 16000 Through 16511 UDP

                    I used Port 16000 for testing

                    12:06:02.006380 IP 185.83.213.25.49331 > 10.10.1.26.16000: UDP, length 0
                    12:06:02.011625 IP 88.119.179.10.52783 > 10.10.1.26.16000: UDP, length 0
                    12:06:02.016003 IP 185.86.77.126.41816 > 10.10.1.26.16000: UDP, length 0
                    12:06:02.018484 IP 185.159.82.88.52425 > 10.10.1.26.16000: UDP, length 0

                    Am I correct this is a win and PFSense is doing as it should ?

                        @cire3 Quick question.

                        Any way to quickly put 10.10.1.25 and 10.10.1.26 in a DMZ for a quick test ?

                        All the DMZ I seen isolate and use different adapters as I understand why. Didn't know if there was a easy way just to test a device passing through the firewall?

                          Actually just realised ncat comes with Nmap.

                          https://nmap.org/

                          Tests look good to me.

                          I'd start tightening up the source rules to the two hosts mentioned in their email once your happy.

                            This is what I have (Does being on a VPN change it ?

                            Should this scan show the other ports ?

                            Scanning 10.10.1.25 [1000 ports]

                            Discovered open port 143/tcp on 10.10.1.25

                            Should I see the others ?

                              I'd run the test when disconnected from the VPN and try to establish what you were told by port forward ties up.
