You can prevent that by transparent proxy.

You can also force use of the proxy by having the firewall on the LTSP
server and blocking port 80 access unless it comes from squid. You can
set up squid ACL to prevent access to port 3128 by anyone but the
dansguardian user. The only port left is 8080 to get into dansguardian.
