14.4 DHCP Client List Screen
The DHCP table shows current DHCP client information (including IP Address, Host Name and MAC
Address) of network clients using the NBG5615’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 Monitor > DHCP Server.
Figure 80 Network > DHCP Server > Client List
The following table describes the labels in this screen.
First DNS Server
Second DNS Server
Third DNS Server
Select Obtained From ISP if your ISP dynamically assigns DNS server information
(and the NBG5615'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 NBG5615 act as a DNS proxy. The NBG5615's LAN IP
address displays in the field to the right (read-only). The NBG5615 tells the DHCP
clients on the LAN that the NBG5615 itself is the DNS server. When a computer on the
LAN sends a DNS query to the NBG5615, the NBG5615 forwards the query to the
NBG5615'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 NBG5615.
Cancel Click Cancel to begin configuring this screen afresh.
