Those are all DNS queries (UDP-53) and one SMTP packet from 192.146.150.3
(TCP-25).
What's happening is that the PF service is rejecting the packets.
Exactly how are your packet filters defined?

Hi
I am hosting a DNS server on the ISA server. I have set up packet filters
etc as in KB articles Q292278, Q291662 to answer DNS queries and zone
transfers.
Can someone explain why these are blocked / what do they mean... taken from
the Packet Filter logs.

If these are for Reverse lookups (there are mail systems that now do these
before accepting mail.) how do I allow it.??
Thanks
