Migrating from IPChains to Netfilters?

Posted by Cliff on from the upgrading-those-firewalls dept.

lodn asks: "I've been using a Linux gateway for some time now. It's a simple kernel 2.2.18 install with IP forwarding. Thanks to the great HOWTO on IPchains I was able to configure it with no problems. Now I'd like to upgrade to kernel 2.4, however I have not been able to find a HOWTO for Netfilters! Does anyone know where such can be found?" Anyone know of any IPchain-to-Netfilter migration utilities? I must admit, I haven't been able to find much information about Netfilter usage either when I went looking into 2.4, however my firewall is also still 2.2. Time to upgrade, methinks.

    There is a HOWTO for netfilter. It's at http://netfilter.samba.org/unreliable-guides/, and it's called the Linux 2.4 Packet Filtering HOWTO. Also look at the Linux 2.4 NAT HOWTO while you're there.

    Simply hitting Google and entering "netfilter howto" ?

    All of the top 5 hits are directly relevant, and 2 of them are to the "Linux 2.4 packet filtering howto" and the "Linux 2.4 NAT howto"

    *sigh* Another day, another totally unresearched "ask slashdot". You'd think the editors would bother spending 2 minutes checking if the question is trivial.
