      easiest way to debug, run tcpdump on pflog0, you are going to see all of the blocked packets and according to which rule they are blocked, if they are indeed blocked.

      tcpdump -nettti pflog0 port 8010 and then run an external syn scan on 8010

        Turned it off, but still not seeding well

        Maybe QBittorrent needs the outbound port to be static.
        Many consumer routers does this, but pfSense use random outbound ports by default. You may have to add an outbound NAT rule to achieve this.

        pfSense said the port was closed when the destination was the WAN IP, but when it was the LAN IP it said it was open.

        ❓
        You cannot use the port check on pfSense for the firewall itself. You can only check other destinations.

          @viragomann if you have port forwarding working, outbound NAT doesn't matter. Making it static just helps with hole punching

            Some programs need this like several games. Maybe QBittorrent as well. I don't know how it works, as I mentioned above.
            But it's for sure that QBittorrent also make upstream connections and these have nothing to do with forwarding at all.

            So a presume, you're knowing well QBittorrent and can possibly give more reliable infos.

              Actually, once I turned off pfBlockerNG, parsec managed to connect to a host game. So those ports are fine.

              The problem is with the torrent, it's better, it's actually seeding now, and it actually reached 300 KB/s, but it does not stay at those speeds, and there's more downtime than actual seeding.

              Maybe QBittorrent as well

              Well, I already had outbound set up, so that's not what's stopping it. The question is why is pfBlockerNG ignoring the rule order, and even with it turned off, why are connections not sticking as they used to?

                So have you tried pflog as I suggested?

                Actually run tcpdump on wan port at the same time to compare incoming and rule matching

                  @lolipoplo No, because you suggested running the tcpdump on the parsec port, and that is solved by just turning off pfBlockerNG.

                  I could run the tcpdump on the qbittorrent port and see what happens.

                    Here's a small output of that command.

                    The weird thing is, when I do canyouseeme, it shows me another public IP than what is shown in the WAN interface on my pfSense box.
                    Both are public IPs, and I tested both, and now they say closed.

                      if you aren't willing to do tcpdump on pflog0 you can't see how your packets get blocked

                              @undertaker666 I only see pppoe0, where's pflog0?

                                @lolipoplo pflog0 was empty, no matches.

                                  pfsense has logging on for all of the default block/reject rules

                                  If pflogs is empty, this probably means your port forwarding is working provided you do not have silent block/reject rules.

                                  one more sanity check, go to your associated pass rules for nat and enable logging, then listen to pflog0 again to make sure they are matched

                                    @lolipoplo Still empty, and I could see almost nothing hits the rule in the auth screen as well.

                                    Even though I ran a check from an online service to see if it's open or not, it did not register, and the test came back as closed.

                                    Something is very weird here. I already did such a check before that returned open, so I'm not sure what happened.
