AH! The light dawns! <g>
Sounds to me as though you need to have the clients use the hosted system
as their gateway, as though they're on a subnet, and have to go through
the hosted system as a firewall (not a bad idea in itself). They need to
*not* look directly out.
Sounds like an iptables setup to route through the hosted system.
Remember, if that works for you, that all the rules for blocking should
happen *first* in /etc/sysconfig/iptables.
