I am as such.
net <--- firewall <--- ltsp server (which has the mac address to ip
table) <-- clients.
Does that make sense? More or less I'm running perfectly normal ltsp
straignht out of the book on a static ip system where thed ip addresses
are assigned on the individual machines (or on hte ltsp server, in the
case of ltsp).

Here's a question. Since all the machines are actually running locally
on hte ltsp box, do they keep their ip's as far as the firewall is
converned? That is, will it see ip.box.1 as different from ip.box.2, or
will they all be ip.box.server?
It depends on where the firewall is and how routing the clients boxes
requests is being and (finally) how you are managing your IP address
space.
In most cases (I think) the LTSP clients get IP addresses which are not
ever going to be publicly (Internet) visible so all of their IP
traffic gets "NAT'ed" to/from the public IP address which is gateway-ed
to the internet. If your firewall is doing the "NATting" then yes, the
firewall sees the internal IP's. That is the case for many networks
that I have done but its not the only way to do it.
Many networks separate the NAT and firewall functions to different *boxen
for both performance and security reasons. On those networks, the
firewall is usually "outside" (on the internet) and the NAT box is
usually "inside" (behind the firewall) so that firewall would never see
the internal (LTSP client) IP's.
*"boxen" derivative of "Vaxen" meaning "possibly more than one".
