If there is a private DNS server that services the VPN, type its IP address here. The
Prestige assigns this additional DNS server to the Prestige 's DHCP clients that have
IP addresses in this IPSec rule's range of local addresses.
A DNS server allows clients on the VPN to find other computers and servers on the
VPN by their (private) domain names.
Local IP addresses must be static and correspond to the remote IPSec router's
configured remote IP addresses.
Two active SAs can have the same configured local or remote IP address, but not
both. You can configure multiple SAs between the same local and remote IP
addresses, as long as only one is active at any time.
In order to have more than one active rule with the Secure Gateway Address field
set to 0.0.0.0, the ranges of the local IP addresses cannot overlap between rules.
If you configure an active rule with 0.0.0.0 in the Secure Gateway Address field and
the LAN's full IP address range as the local IP address, then you cannot configure
any other active rules with the Secure Gateway Address field set to 0.0.0.0.
