10.6  Client List Screen
The DHCP table shows current DHCP client information (including IP Address
Host Name and MAC Address) of network clients using the NBG-417N’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. 
First DNS Server
Second DNS 
Server 
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.
Apply
Click Apply to save your changes back to the NBG-417N.
