tunnel network traffic between two peer devices over another network (like the
Internet).
First DNS Server
Second DNS Server
Select From ISP if your ISP dynamically assigns DNS server
information (and the NBG-419N's WAN IP address). The field to the
right displays the (read-only) DNS server IP address that the ISP
assigns.
Select User-Defined if you have the IP address of a DNS server.
Enter the DNS server's IP address in the field to the right. If you
chose User-Defined, but leave the IP address set to 0.0.0.0, User-
Defined changes to None after you click Apply. If you set a second
choice to User-Defined, and enter the same IP address, the
second User-Defined changes to None after you click Apply.
Select None if you do not want to configure DNS servers. If you do
not configure a DNS server, you must know the IP address of a
computer in order to access it.

MAC address by either using the NBG-419N’s MAC address, copying
the MAC address from a computer on your LAN or manually entering
a MAC address.
