If there is a private DNS server that services the VPN, type its IP address here.

The ZyXEL Device assigns this additional DNS server to the ZyXEL Device 's

A DNS server allows clients on the VPN to find other computers and servers on

the VPN by their (private) domain names.

configured remote IP addresses.
Two active SAs cannot have the local and remote IP address(es) both the same.
