Hi
I an running a DNS Server on the ISA server as the DNS server is
authoritative for our public domains.
I have set it up following the various articles at isaserver.org and at
microsoft.
But I have had complains that external people are unable to get a reverse
lookup on the IP addresses used by our mail servers.
Below is the DNS packet filters I have used..
