DNS Zone Transfers not working

Hi all,
Just a quick question re DNS zone transfers and the DNS application
filter.
I have the DNS zone transfer from privileged/high ports options set in
the intrusion detection filter.
If I do an nslookup (ls -d domainname.co.uk) from an ip external to the
firewall, the zone is transferred fine. Naturally an alert is generated.
However, if I deselect these check boxes, restart ISA and try this
again, the nslookup process hangs on the ls -d domainname.co.uk command.
Could someone confirm this behaviour happens with their firewall. If so
why ?
Patrick
