All my machines have a default route set, but there is only an
"internet" connection when the modem (in a remote firewall) is dialed up.
I think that the ping idea (or try a small tcp connection to a know good
host) is best, as even a DNS lookup (something I wondered about) could
give false positives with a caching nameserver.
