The DHCP table shows current DHCP client information (including IP Address, 
Host Name and MAC Address) of network clients using the NBG-416N’s DHCP 
servers.

Configure this screen to always assign an IP address to a MAC address (and host 
name). Click Network > DHCP Server > Client List. 

Note: You can also view a read-only client list by clicking the DHCP Table (Details...) 

hyperlink in the Status screen. 

The following screen displays.

First DNS Server

Second DNS 
Server 

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-416N act as a DNS proxy. The 
NBG-416N's LAN IP address displays in the field to the right (read-
only). The NBG-416N tells the DHCP clients on the LAN that the NBG-
416N itself is the DNS server. When a computer on the LAN sends a 
DNS query to the NBG-416N, the NBG-416N forwards the query to the 
NBG-416N'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.
