Thanks TP

1.	 Can only my thin client s use eth0 as a default gateway?  What if I
have XP clients?
2.	I’ve worked with the iptable config file before.  But sorry, I don’t
understand, what is iptables-fu?

Is the following scenario correct?
I have eth1 going to the cable modem and eth0 to my switch.   Then I need to
set the gateway of my workstations (not thin clients) to eth0 for them to
have internet access.  But I can choose whether or not to set the proxy to
eth0 (for web filtering) on each workstation.


Sounds like you're making your LTSP server also function as your Internet
router for the entire site.  Nothing wrong with that,, and your setup is
correct, but just make sure you've got the proper iptables-fu in place
before you go live with it!  Last thing you want is for your LTSP server to
get nailed by some cracker.

And yep, your thick clients would use eth0 as the default gateway.  IIRC,
ip.forward and NAT are both turned on by default in K12LTSP.
