      @root1ng where do you see 172.16.1.6 respond with traffic to its 9987 port?

      I don't see a response to 192.241.153.165 port 53781 in what you posted.

        Yes, you are right, I checked once more and there is nothing from me to that ip, only from him to me.. I don't know what else to do, do you think you could help me by sharing or teamviewer?

          @root1ng if you see traffic sent to that IP.. Check on that device that actually listening. Netstat -an will show you ports being listened on.

          for example

          listen.jpg

          Some udp ports my windows box is listening on.. Do you see that 9987 listed?

          do a packet capture on the device, wireshark is free and 2 seconds to install, etc..

            The server is on linux (ubuntu), not on windows, I still ran the same command, I attach a picture below.

              @root1ng so that is good its listening - so firewall is running, its not answering for some other reason, its sending return traffic elsewhere?

              So fire up wireshark or tcpdump and validate the traffic is getting there..

              Pfsense did its thing, clearly it sent the traffic.. It has no control to if it gets an answer or not.. Which from your packet captures it did not.

              edit: Oh wait - why does it not show Listen as state?

              nolisten.jpg

              edit2: my bad - its UDP ;) having a brain fart this morning that we dealing with UDP ;) sorry..

              Since you see pfsense sending it on, you need to sniff on the device itself - is it seeing it? If so does it answer to something other than pfsense? might have to validate what mac address is sending to if you see a response to that IP your checking from.

              Does it not see it at all - its getting lost between pfsense and your device.. Or its application just didn't answer, or some firewall on the device not letting the application see the traffic.

                I don't know why he doesn't listen, I don't have a firewall on neither on the virtual machine nor on Proxmox, I don't know what else to do... the situation is too complicated...

                  @root1ng see my edit, sorry about that - udp with netstat wouldn't show "listen" state.. like tcp does.. but you can see its listening.

                    I don't really have anything to check on the device, everything is default, firewall off, the firewall for that virtual machine is off from Proxmox, I don't know what else to check and how..

                      @root1ng on the VM install tcpdump.. sniff with that, depending on the distro you installed might be already installed.

                      tcpdump.jpg

                      You can set filters on it so only looking for your udp 9987 port.

                          @root1ng In Proxmox you have a Firewall Option for every VM and every vNIC. Have you checked both?

                            Hey,

                            VM Firewall:
                            Screenshot_7.png

                            Screenshot_8.png

                            What I want to add is that, even with Firewall ON or OFF on the NIC, I still can't connect, I tried all the possible options, but without result.
                            The firewall is not active on all virtual machines, including the main node.

                              @root1ng Disable this checkbox on all the VM NICs, on your pfSense and your Linux Server.

                              I am running TS on a Linux VM (Debian) behind a pfSense VM on Proxmox too, it is running fine for me, just checked. 😉

                                  @root1ng Maybe the host firewall, what Linux are you using exactly?
                                  Maybe a routing problem, you could show us your proxmox network.

                                  In the beginning you had no hits at all on your rules. Have you fixed something or is your testing flawed otherwise? Send me your IP, I will check if I can connect.

                                  Also show your rules on that VMs LAN.

                                    The idea is that traffic appears in pfSense to the rules in the firewall, but only when I check the ports.
