True enough...  However, in my case anyways, it's not an issue.  I
already have a box that's using an ISP assigned IP as a gateway, but
using aspects of the above solutions, I can now have all my DMZ
servers funnelled through the one machine.

That means that traffic control/shaping and bandwidth monitoring
should become real easy, as it means one access point into/out of the
network, but still with IP assigned IPs on the DMZ machines.

Sorry if this is not news to anyone else, it's an amazing revelation
to me. :)
