Outbound DNS

Benderle
Hi all,

tried to search and came up dry.  but I have a question, and forgive me in advance if it's a bone-headed one.  Knowing that attackers try to use DNS to fingerprint networks, is it a good idea to have a packet filter rule to allow outbound DNS requests from the internal network?  

Currently i have my ASG220 running my PPPoE access, and serving as the public IP addy endpoint,  and it automatically gets DNS forwarding server info from the PPPoE connection.  so do i need the packet filter rule:

Internal network --> DNS ----> Any   "Allow"   ?

[:S]

or can i just turne that rule off?
