please take this problem, and all related threads, to
<dns-operations at>.  this is NANOG.  there
are plenty of people on that other mailing list willing
to help and interested in helping with DNS issues.

fwiw, we all know that udp port randomization isn't a
panacea and that it will break many previously-working
configurations.  we just don't know what else to do NOW
while we wait for godot or whomever to deliver us DNSSEC.
