I'm using a DHCP relay agent on the FreeBSD router. You don't need to
have a DHCP server in the same subnet as the thin clients if you're
relaying the DHCP requests to a DHCP server in another subnet. DHCP
wasn't the issue at all since I could get an IP and boot up via TPFT.
It was getting 90% of the way through the boot and then hanging when it
tried to NFS mount the server. This was likely due to the issue with
large UDP packets. I changed the pxelinux.cfg/default MOPTS file to
switch NFS over to TCP and specify smaller UDP packets and that resolved
the issue. I don't know which did the trick (TCP or smaller UDP packets).
Thanks!

Doing any UDP forwarding? NFS uses UDP for it's work. That's probably
the root of your problem.
How are you handling dhcp with a router in between? Why not just put
the ltsp server on the same subnet?
Not to mention that probably the DHCP traffic cannot reach the dhcp
server.
Try installing the dhcpd server on the freebsd box and poing with the
'next-server' option (see the wiki) to the real NFS server. Also (also
in the wiki) see how you can modify via the MOPTS variable the NFS
mount to be done via TCP. But you should also allow UDP traffic
through the freebsd box (so the LTSP stations can get the kernel via
TFTP from the TFTP server, I presume it's the same as the NFS/DHCP
server now) otherwise try putting it also on the freebsd box.
