DESCRIPTION
Select From ISP if your ISP dynamically assigns DNS server information (and
the NBG-417N'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 DNS Relay to have the NBG-417N act as a DNS proxy. The NBG-417N's
LAN IP address displays in the field to the right (read-only). The NBG-417N
tells the DHCP clients on the LAN that the NBG-417N itself is the DNS server.
When a computer on the LAN sends a DNS query to the NBG-417N, the NBG-
417N forwards the query to the NBG-417N's system DNS server (configured in
the WAN > Internet Connection screen) and relays the response back to the
computer. You can only select DNS Relay for one of the three servers; if you
select DNS Relay for a second or third DNS server, that choice 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.
Click Apply to save your changes back to the NBG-417N.
Click Reset to begin configuring this screen afresh.
