Yeah, I use 2.2.19 on my server (2.4.x is the most unstable 'stable series' i've ever seen..). ipchains is like this:

Incoming Outgoing
interface interface
----+ +------->
| ^
v +------------> forward -----------+ |
input | |----> output
+----------> Application ---------+

I actually like it that way, it makes it easier to block things from the dsl ether (eth0):

ipchains -a input -i eth0 -d ! 66.92.237.176 -j DENY -l

With iptables i'd need that on both the INPUT *and* FORWARD rules...
