MAC Address Type the MAC address (with colons) of a computer on your LAN.

DNS Server

DNS Servers

Assigned by

DHCP Server

The NBG-419N passes a DNS (Domain Name System) server IP

address (in the order you specify here) to the DHCP clients. The NBG-

419N only passes this information to the LAN DHCP clients when you

select the Enable DHCP Server check box. When you clear the

Enable DHCP Server check box, DHCP service is disabled and you

must have another DHCP sever on your LAN, or else the computers

must have their DNS server addresses manually configured.

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 DNS Relay to have the NBG-419N act as a DNS proxy. The

NBG-419N's LAN IP address displays in the field to the right (read-

only). The NBG-419N tells the DHCP clients on the LAN that the NBG-

419N itself is the DNS server. When a computer on the LAN sends a

DNS query to the NBG-419N, the NBG-419N forwards the query to the

NBG-419N'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-419N.
