Don't we meet in unusual places! (inside joke)  Just a note, I'm
reconfiguring my whole home network (in preparation for DSL as well). 
What you might consider doing is putting together an old 486/pentium xx
to function strictly as your firewall.  You could probably pick one up
for near nothing these days.  I'm working on putting together the
bastion/choke configuration from Ziegler's book.  More as a learning
experience then a necessity.

I'm afraid there will be more problems with W2K than there were with
