VPN Group Configuration DNS Redirection Tab

The primary server specifies the primary IP address of a DNS server. If a 
Primary Server has been set, then the VPN Client will tunnel all DNS queries 
to the IntraPort and the IntraPort will take all DNS queries bound for the 
client’s primary DNS server and send them to the specified address. The IP 
address should be in standard dotted-decimal notation.

The secondary server specifies the IP address of a backup DNS server. A 
primary server must be specified before a secondary server is chosen. The IP 
address should be in standard dotted-decimal notation.

The split server specifies the IP address of a "split"  DNS server. This is useful 
for setups where queries for internal names are handled by one server (the 
primary server) while queries for external names are handled by another 
server (the "split" server). The IP address should be in standard 
dotted-decimal notation.

This list specifies the domain names that will be compared to the name in 
DNS queries to the DNS server in order to determine whether the query is for 
an internal or external domain.
