The security gateway offers many scenarios for implementing DNS. The scenario you choose depends
on how your current network is configured and your DNS objectives. Use the scenario descriptions
below to help you decide how to implement DNS for your network. The first scenario is to have a
caching name server and this option is configured by default out of the box. You may not have to do
any further configuration if this is the option you require.
DNS Authority Record Properties—General tab
An authority record defines the name server that is responsible for a given domain. The DNS proxy is
only authoritative for those domains and networks defined through the DNS Record Properties dialog
box.
For any given domain, there is only one name server delegated as the primary DNS server for a domain.
You can make the DNS proxy authoritative for both public and private requests.
