 Chapter 12 DHCP Server

EMG6765-Q10A User’s Guide

The DHCP table shows current DHCP client information (including IP Address, Host Name and MAC 
Address) of network clients using the EMG6765-Q10A’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 57   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 
EMG6765-Q10A'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. 

Select DNS Relay to have the EMG6765-Q10A act as a DNS proxy. The EMG6765-Q10A's LAN 
IP address displays in the field to the right (read-only). The EMG6765-Q10A tells the DHCP 
clients on the LAN that the EMG6765-Q10A itself is the DNS server. When a computer on the 
LAN sends a DNS query to the EMG6765-Q10A, the EMG6765-Q10A forwards the query to 
the EMG6765-Q10A's system DNS server (configured in the WAN 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 EMG6765-Q10A.
