Re: [tlug] Does Linux need, or have, a firewall?

Ian, Evan,

    Thank you for the command. I have included the results below. It 
doesn't say anything about aMule on port 80.
  
    However, Firestarter still does. I've put a screen shot here:
    http://www.autotelic.com/firestarter.png

    And, since I've now found the handy "take screenshot" function in 
the Gnome panel, I've included the port mapping and DHCP settings that 
I've set up on my router:
    http://www.autotelic.com/dhcp-settings.png
    http://www.autotelic.com/port-mapping.png

    And, as I did all this, aMule is reporting that I have a "lowID".

    Does any of this information help point towards the root of this 
problem?
