From a wiki page I wrote for myself a few years ago. It may be a bit dated.
"Enabling fat clients to work on the thin client segment
K12LTSP has this enabled by default; K12Linux does not. To enable it:
* echo 1 >/proc/sys/net/ipv4/ip_forward
* edit /etc/sysctl.conf to make that permanent
* iptables -t nat -A POSTROUTING -j MASQUERADE
* service dnsmasq start
The first two turn on forwarding, which is the primary requirement. The next two
tell iptables to allow port forwarding; if iptables is turned off, they are
unnecessary. The last one is to provide a DNS service to the fat client.
Remember that thin client's apps are running on the server so they use the DNS
server listed in /etc/resolv.conf. On the TC segment, however, dhcpd.conf tells
clients that the nameserver is the LTSP server, meaning there needs to be a
nameserver running on the LTSP server. That's what dnsmasq does. Or you can give
out the address of a different DNS server via dhcpd.conf."
