DNS Server 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 Local IP addresses must be static and correspond to the remote IPSec router’s
configured remote IP addresses.
Two active SAs cannot have the local and remote IP address(es) both the same. Two
active SAs can have the same 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.
Addr Type Press [SPACE BAR] to choose SINGLE , RANGE , or SUBNET and press [ENTER].
Select SINGLE with a single IP address. Select RANGE for a specific range of IP
addresses. Select SUBNET to specify IP addresses on a network by their subnet
mask.
