Here's the general way to do it with any Linux-based system, be it
Slackware, Red Hat, *ubuntu, whatever:
echo 1 > /proc/sys/net/ipv4/ip_forward
This assumes that your standalone Linux boxes are on the LTSP client
subnet. You will also have to turn on IP masquerading, which should
already be on by default, I believe.
