Without looking in detail (yet) at your tcpdump, what I'd suggest is trying
to install one of the alternative dhcp servers on your ltsp server.  The
options I know of are udhcpd or dnsmasq.  I'm not certain of the config
details with those though.

The main reason for this is simply to be able to say "there _must_ be
something amiss in dhcpd".  Also, it will solve all your other issues
above in terms of not requiring users to do anything different.
