hmm... perhaps you need to set the default router, /etc/defaultrouter.  You
can check the
/etc/defaultrouter
file on guam and compare it with that of yorktown. Perhaps yorktown does'nt
know how to get
past it's
local network.  If that does'nt work the next step I think would be a
traceroute to see where
it's failing at.
