Situation:
------------------------------------------------------
Internal DNS ( Primary & Secondary )
-------------------------------------------------------
|
------------------------------------------------------
F/W with caching DNS
------------------------------------------------------
|
------------------------------------------------------
External DNS ( Primary & Secondary )
-------------------------------------------------------
Internal DNS is configured as a forwarder and pointed to Cache DNS
Cache DNS ( on F/W ) is configured as forwarder/slave to External DNS
External DNS registered with NIC
Question:
Along with configured settings do packet screen rules have to be configured
to pass DNS traffic from outside to inside and vice versa or, will
configured DNS settings be suffice.
Thanks in advance,
Kevin
