[UFO Chicago] NAT in 2.6

[Ian Bicking]

Hi UFOers.  Long time no see.  But I fear I come to you with ulterior 
motives.

In some upgrade on my Debian Unstable box my 2.4 kernel broke with 
respect to my sound card, upsetting my otherwise happy world.  After 
trying all sorts of things, I eventually got a 2.6 stock Debian kernel 
to work with the sound card.  But then my NAT stopped working.  I think 
that's all changed for 2.6, so maybe I just need to revisit it entirely. 
  So I come to you!

Right now I have a script in /etc/init.d/ipmasq, that just runs 
/usr/sbin/ipmasq, and I think by some magic I configured it at one time, 
though the stuff in /etc/ipmasq certainly isn't my doing.  I don't want 
to do anything fancy, just simple NAT, not passing through any incoming 
connections, very simple.  What's the best way to go about this?  There 
seems to be a couple packages in Debian, and maybe more if I knew what 
the proper term was these days (like: did ipchains obsolete iptables, or 
the other way around?)

So what you recommend?

Thanks...
