Pix 501-Protect DNS Server

I have configured a Pix 501 to protect a DNS server using the following config. Clients should only be able to conduct Zone transfers and DNS, other than this I want to lock the server down.

However, when I use http://www.kloth.net/services/nslookup.php to test the server, it responds

"server can't find 7.1.1.207.in-addr.arpa: NXDOMAIN"

Any comments on this config?
