    Question Firewall help needed


    I am having a problem with a firewall on a PC running Linux Mint 12.
    I have used Firestarter to set up the iptable rules, the same as I have many times before but whenever I do a ''ShieldsUP! firewall test it fails (even though the squares are all green) saying that the computer responds to ping requests. I also get 'Serious' events on Firestarter.
    I have gone though all the settings on Firestarter and made sure they are the same as another Mint PC which is secure. I have also: used the iptables import\export feature with the secure PC unsuccessfully, tried flushing iptable rules and starting again and using the terminal (with sudo) to manually block ping requests but still fail the test and get serious events logged in Firestarter.

    What else can I try to get this computer secure online?

    Thanks

    A different firewall GUI. Firestarter has been depreciated for ages. Not only is it old and out of date, but from what I've read about it, it actually (potentially) opens up security holes because of of the mode it runs in. I'd uninstall it.

    If you're looking for a really simple IP tables front end then install gufw.

    If you're looking for a better interface with more granular control then firewall builder looks like it might be pretty cool.

    I haven't tried it yet, but it's on my list and in the repos.
