Using the router to do NAT seems to make alot of sense for some people but
I feel that you should let the router do what is primarily its main
function : i.e providing routing . Well , many people may disagree with me
on this but NO FLAMES PLEASE.

===========================================================================

Not a flame, just a difference of opinion...I've spent the last 9 years or so
involved with routers, and I would have agreed with you completely, oh, until
about the last 2 years or so. Router hardware has taken a major leap, and the
processing power available to most routers these days is way way more then
most "edge" routers require to accomplish their routing tasks. That being
the task, why not use all that leftover power to do NAT and other useful
things ?

I would think that a good approach would be to define what needs doing and
then find the appropriate system to accomplish that. In this case "system"
may include a multiplicity of devices.
