  1. Just a quickie question ...

    i read somewhere that iptables is a kinda enhanced version of ipchains.

    So if I want to do firewalling, NAT and such, is it enough just to install iptables ?

    You need to have network packet filtering in kernel too.

    I meant you need to enable that in the kernel, ie. compile, if it's not in it already.

    Networking support - Networking options - Network packet filtering (replaces ipchains) - IP netfilter configuration, select what you need. If you're not sure, I don't think it'd hurt to select all of them. Descriptions should explain them a bit.
