Everything fine when DNS is Outside.If i place a DNS in INSIDE, i cant able to even browse and does not reslove.

i have enabled fixup protocol domain 53, static mapped, access-list for UDP configured..

where i am wrong?.

I am using alias command for my INSIDE Webservers..do i need to remove alias and check?

Pls help......

Rajan,

First - disable fixup DNS that's not for your scenario.

Second - your DNS server should not be NATed, or it'll be definitely non-authoritative and "possibly" lame.

Place it on DMZ and use "nat 0" with proper access lists.

Third - it's recommended to disable the zone transfer to all except the servers listed as NS for that zone.

Fourth - be sure that you have the latest BIND (Unix/Linux/etc) or NT2K with the latest security patches installed.
