    Default Old PC For a Firewall - Suggestions

    Hello,

    Today my CIT Teacher proposed a project for extra credit, He said that he would like to have a firewall that was built out of a older PC that we could possible use for a small network. Since i love learning about computer security and all i went ahead and told him that i would give it a try. So i did some google searching and found some info and was off to a good start. I was just thinking that before i got started i would post this and see if anyone had any suggestions that might help me out.

    Thanks,
    Johnny Boy

    Not sure if non-members can read this, pretty sure you can though.

    We've just been discussing this the last few days.


    Well crap! Guess you can't as a non-member.
    Of course, if you really wanted to have some fun, go to Wal-Mart late at night and ask the greeter if they could help you find trashbags, roll of carpet, rope, quicklime, clorox and a shovel. See if they give you any strange looks. --Streaker69

    Yeah, Offtopic threads can't be read by non-members.
    A third party security audit is the IT equivalent of a colonoscopy. It's long, intrusive, very uncomfortable, and when it's done, you'll have seen things you really didn't want to see, and you'll never forget that you've had one.

    Endian and SmoothWall are the ones I use when making a firewall out of an old PC. Don't forget your 2 ethernet cards :P

    If you really want to impress the teacher setup an OpenBSD fw with PF.

    Smoothwall is very easy to install and setup. You need two cards.

    http://www.smoothwall.org

    IPCop is a offshoot of smoothwall it is also very easy to use.

    http://www.ipcop.org


    For more generic info on "which one to choose" have a look at

    good luck.

    If you're running Ubuntu, or BT or any other *nix distro, do you even need a firewall?

    Just wondering.

    Smoothwall gets my vote, too. I've used it on a couple of firewalls. It has a lot of features, including traffic logging and graphing, and Snort for an IDS.

    Use two, three, or four NICs depending on if you want things like a wireless on a separate net, or a DMZ.

    It can't hurt and as the OP said it was for extra credit.
