iptables

[Labitt, Bruce]

I am trying to configure my firewall at work.  I need to have an
internal trusted network (my number-cruncher) and everything else.  The
trusted network is on eth0, and the other is on eth1.

How do I set this up?  IIRC I had this setup for my myth-box.  However,
I haven't found the answer in the archives.

I'd check my machine at home - but I haven't enabled ssh.  

Is there a quick answer to this?  IIRC Ben ended up sending a reasonable
solution.  Ben, do you remember this?
