Hi, to get started with ipchains i recommend you this very good book: Robert Ziegler: Linux Firewalls (New Riders) I dont agree, that ipchains is completely outdated (yet). State machines, as come with iptables, _may_ increase your security. But bugs here let your network wide open - we've already seen ways to this ;-) Sandro Littke. -- Sandro Littke CIT Jena Computer- und Informationstechnik Consulting Tel. +49 3641 363700, Fax 363701, mobil +49 172 5214549
