    Yes, from the other ISPs, dig @their.servers and dig @my.own.servers works
    fine. On SAIX, dig @anybody.server only gives me a timeout.

    The box uses ipfw in a stateful setup, but even with that comletely out of
    the way, there's no difference.

    /etc/resolv.conf is static, but the address in there is correct.
