host unreachable. -- a bit more info

[Lyle Giese]

sorry about that. I don't normally use these options But it's

dig @146.6.211.1 +tcp arlut.utexas.edu
dig @146.6.211.1 +notcp arlut.utexas.edu

But UDP is default and the second query should have been transmitted
using UDP. The end result is that you have TCP and UDP port 53 openned
properly in the firewalls between the two sites. BTW, zone transfers are
done using TCP because of their size. Small queries try to use UDP first.

This is starting to sound more like the master is not allowing your site
to get a zone transfer. That is an ACL issue for the master site.
