I get nearly identical symptoms with a rather different setup.
System: CURRENT/r263263
Unbound: disabled (as far as I can tell)
Nameservice: using bind99 from ports. This worked two days ago and
then yesterday - blammo!
This system is the default nameserver for the LAN, and queries from
other clients seem to be accepted and answered. Only the machine itself
is blind.
Other independent network services seem unaffected, and I can telnet to
port 53 on my ISP's public nameservers.
Respectfully,
