    Linux Firewall


    I came across a site for Linux firewall based on ipchains so I thought I post a link here if anyone was interested. See http://www.tldp.org/HOWTO/IPCHAINS-HOWTO.html

    I someone could dumb this down for the newbies/me can better understand the basics of a linux firewall (port filtering and or ipchains) I'd appreciate it. Or if there are popular 3rd party app's that make it easier for the new user. Please post in the newbie section. Thanks

    Most new distros now come with IPTables support, instead of, or as well as IPChains.

    IPTables is the "newer version" of ipchains, and imo, much better.

    For some interesting tutorials on Iptables, have a look here:
    http://www.netfilter.org/documentati...html#tutorials

    I would also recommend a book from the red hat press, "Red Hat Firewall Administration" i think it was called, pretty good.

    A lot of people use pre-made IPtables scripts, personally, i think freshmeat.net has one of the best repositories:

    Yeah...the basics of IPTables are really not that hard to grasp. The syntax is a little unfriendly, but once you write a few chains it gets easier. IMHO NAT is the thing that needs a tutorial...most IPTables things that I've read don't explain what NAT is/does very clearly.
