Is the network card on the node showing as "up" on ifconfig? I believe you need to set up IP Masquerade. At least I think it would be one way to set things up so it worked.
http://newbiedoc.sourceforge.net/networking/homegateway.html#NETWORKSETTINGS Livecd probably set this up automagically when it saw you had two cards, one with an external adress and one with an internal adress. If that doesn't work you can try setting up a throw away box as a firewall machine with "Smoothwall" (http://www.smoothwall.org) or something similar and hook that to your switch. This is a totally lazy solution to the problem since then you can just use one nic on your head node and let smoothwall set up the gateway for you. I recently ran into this problem again when I was trying to set up a new cluster on a separate subnet. I chose the lazy solution myself this time, though I will look through my notes from when I set this up by hand when I am at work tomorrow.
