I may well not have fully figured out what was going on
in this particular situation.  Mostly because I got tired of
trying to sort out the endless mysteries of IPv6 running
under XP Service Pack 2.

Teredo may or may not have been at issue.  I saw some
analyses indicating this might have been the case.  In any
event, after backing it and IPv6 out, all was well.
