How to Open a Port for Software or File Sharing



  • I tried to open a port for the file or game sharing software
    But it does not work for some reason

    I went to Firewall and then to NAT
    I clicked Add and filled in the details

    Here is a picture of the settings screen
    Are the settings correct ?
    Or maybe I did something wrong ?

  • You would need to post your firewall rules for us to see the whole picture. It was I, I would create an alias and a floating firewall rule.

    What is the difference ?

    Does the traffic even hit your wan?  This is simple test with packet capture and then generating traffic to the port.

    If does, then does it send the traffic out to your lan device?

    If this is the correct lan device - do you get an answer?  If not the service is not listening on that port or that device is running a firewall, or maybe doesn't even use pfsense as gateway etc..

    I did not understand

    The software runs and downloads files at a fast rate

    But the sign shows I'm behind a firewall (Attached Image)




  • Start a packet capture on WAN and then try to access your server from outside your LAN.  The capture will either show your traffic or not.  If not, it is being blocked upstream somehow.  If oyu see the requests coming in on WAN, the next step is to start a capture on LAN and look for the forwarded traffic leaving to your server.

    Basically, you have person A talking to person B with a msg for Person C.  Packet capture on WAN tells you if B is hearing from A, and the capture on LAN tells you if B is talking to C.
