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.
Reset Click Reset to begin configuring this screen afresh.
