No NAT for Port 4444?!?!?!

  • Hi folks,

    I'm a bit confused. My pfsense doesnt redirect Requests from port 4444 to <internl ip="">https?!?!?
    Ok, that could be. Server down, Service not available or Provider blocks is.
    But when I change the port to something else, like 5555, everything works fine.

    Does anyone has a glue why that is?!?!?!
    I aalready checked google and found no good answer.
    My pfsense version is 2.0.3Relase AMD64.
    It worked with port 4444 longer than 2 years.

    any one a suggestion?


  • Need more specifics to even begin.

    Post network map.
    Post port forwards
    Post firewall statements.

    What do you mean more info - you mean I can not just call the auto mech and tell him my car won't do 100 miles an hour?  He needs to know if has gas, does the engine start, does it have tires, etc.

    Even If I tell him it use to do 100 miles an hour before ;)

    Snort blocked incoming port 4444? UPNP claimed the port for something else? (can that happen?)
    There appear to be some known worms that use port 4444 so maybe your ISP blocked it as you say. Maybe you have that worm.  ;)


  • Hi,

    worm?!?!? My Company ist there connected.  :o

    snort isn't installed, upnp is disabled.
    Is it used for another Service by pfsense?
    Portlist says: 4444-4445 TCP I2P HTTP/S proxy
    Maybe our ISP really block the Traffic.

    If you don't have snort installed and your box has previously been working fine on that port then I would suggest your ISP is blocking it for whatever reason. Try asking them.  ;)
