I have been through the same process recently using a redhat system,
(1) Edit /etc/sysctl.conf, change
net.ipv4.ip_forward = 0
to
net.ipv4.ip_forward = 1
In my case I enable the firewall on the LTSP server, eth0 to only allow
port 22 (SSH) in, the secret to getting this to work is to tell your
modem router about the second network on eth1.
My modem / router is administered with a web browser, so I log into it
and change the route table to add the new route
Destination Netmask Gateway
