RE: How to block only MX query made to DNS server

[pravin rane <pgr_80@yahoo.com>]

That is right but only when all clients are using my
DNS server. I will not be able to block MX requests if
they are using some other DNS servers which are
out-side of my network and I can not force my clients
to use only my DNS server.

Using iptables I can build a rule for certain ICMP
TYPE Packets. Is there any rule which can match DNS
query TYPE?
