Just a note of caution about this specific point, against an  
admirable & detailed reply-- from what I understand from another  
mailing list is that the newer versions of the Speedtouch DSL modems  
no longer have the capability of acting in "bridging" mode and will  
always run in the 1-to-1 NAT translation mode.

This turns out to represent a significant problem for people who want  
to provide NTP services to the world, perhaps via the NTP pool  
project, as the rather limited NAT state table in these DSL modems  
easily overflow when dealing with many stateless UDP packets....
