DSL Modem gets the external IP.  But I also found in the web-based modem 
configuration utility that all I need to do is click one check box to enable 
NATing of incoming SSH requests. It just works.

The modem has two options for connection type: "Always On," and "On Demand" 
(I had been useing "On Demand" before.  Is it reasonable to assume that the 
"Always On" option will hold on to the IP?

I've heard of VNC, but never used it.  Is there a good how to or easy way to 
set it up?
