Re: dns server

[Raymond Leach <raymondl@knowledgefactory.co.za>]

What are you trying to accomplish?

Allow clients internally to query your DNS server?
Allow your DNS server to query root servers and forwarders?
Allow external people to query your DNS server?
Allow updates to slave zones on your DNS server from external DNS servers?

You should create specific rules for these situations rather than generic 
rules.
