Hi Linux Gurus,
I need help for Linux DNS on which I can enable security for my organisation.
Hope I will be able to do below mentioned (# 3 & # 4) through Linux DNS.
LINUX DNS server is in Cisco Firewall DMZ zone.
I have four queries:
1. Linux DNS should able to resolve the DNS query for internet. ( I can do this).
2. Linux DNS should send resolution of my domain xyz.com, zone hosted on server. (I can do this).
NEED HELP FOR BELOW MENTION Queries
3. Any other query for any domain other then xyz.com domain should not be resolved.
4. Should reply queries from authoritative server for xyz.com doamin should be resolve.
Thanks in Advance
