RE: [K12OSN] will this setup work?

Ok, so I put Ipcop in between my modem and k12 box.  I have the internet on the server and clients, so most everything is ok, except that my windows machines attached to the switch are not finding the internet.  I get a notification that there is "limited or no connectivity".  I swear that I had this exact setup for years, but now its not working.  Ever since Comcast bought out Adelphia, I've had issues. 

I checked services; nat is running.

On a 2-nic machine, the iptables setup to act as a nat gateway should be
in the nat init script included in k12ltsp.

service nat start
chkconfig nat on (to restart automatically at bootup)

Yes, but on the 'outside' interface, many of the k12ltsp services will
be blocked. Freenx/NX should work with the 'use ssl for everything' option.
