  1. Wow, what a great article. by thegnu · · Score: 5, Funny

    I have bookmarked it. This is the kind of crap I love. I just today acquired a Cassiopeia E100 for free, and I'm going to a)install Linux on it, and b)see if I can get wireless running on it. This is gonna be awesome.

    My favorite software slogan ever is for ethereal, "Sniffing the glue that holds the internet together"

    I'm sure a lot of you know this but this is in reference to TCP/IP being called "the glue that holds the internet together" Oh so funny. And oh so off-topic. I'm sorry. I love you guys.

    The problem with IPCop and Smoothwall for that matter, is the inability to filter traffic outbound.

    But one of the neat things about IPcop is that it's one of them open source things. So while youre quite correct that the pretty GUI doesnt have an interface for egress filtering, you *can* hop into the shell and add in the iptables commands of your choice.
