  If you wanted to run multiple servers, you would want separate
(static) external addresses for each.  Of course, most cable modem
providers don't really want customers to do that, either....

  It's true:  A gateway or router can make an entire LAN look like a
single (rather active) machine.  Of course, if you want the provider
to *support* your configuration, they need to know about it and agree
to do so -- otherwise, you'll get no help from them if it breaks.  To
some people, that might be worth a bit extra each month.
