tunnel network traffic between two peer devices over another network (like the
Internet).
NBG-419N User's Guide
DESCRIPTION
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.
The MAC address section allows users to configure the WAN port's
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.
Select Factory default to use the factory assigned default MAC
Address.
Select Clone the computer's MAC address - IP Address and
enter the IP address of the computer on the LAN whose MAC you
are cloning.
Select this option and enter the MAC address you want to use.
Click Apply to save your changes back to the NBG-419N.
Click Reset to begin configuring this screen afresh.
