DESCRIPTION

First DNS Server

Select From ISP if your ISP dynamically assigns DNS server information (and

Second DNS Server

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-Definedif 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-Definedchanges to None after

 

you click Apply. If you set a second choice to User-Defined, and enter the

 

same IP address, the second User-Definedchanges 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.

 

 

Apply

Click Apply to save your changes back to the NBG-417N.

 

 

Reset

Click Reset to begin configuring this screen afresh.
