EMG2926-Q10A User’s Guide

11.4 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 EMG2926-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.

MAC Address Type the MAC address (with colons) of a computer on your LAN.

IP Address Type the LAN IP address of a computer on your LAN.

DNS Server

DNS Servers

Assigned by DHCP

Server

The EMG2926-Q10A sends a DNS (Domain Name System) server IP address (in the

order you specify here) to the DHCP clients. The EMG2926-Q10A only sends this

information to the LAN DHCP clients when you enable DHCP Server. When you disable

DHCP Server, DHCP service is disabled and you must have another DHCP server on

your LAN, or else the computers must have their DNS server addresses manually

configured.

First DNS Server

Second DNS Server

Third DNS Server

Select Obtained From ISP if your ISP dynamically assigns DNS server information

(and the EMG2926-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. 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 EMG2926-Q10A act as a DNS proxy. The EMG2926-

Q10A's LAN IP address displays in the field to the right (read-only). The EMG2926-Q10A

tells the DHCP clients on the LAN that the EMG2926-Q10A itself is the DNS server. When

a computer on the LAN sends a DNS query to the EMG2926-Q10A, the EMG2926-Q10A

forwards the query to the EMG2926-Q10A'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 with the EMG2926-Q10A.

Cancel Click Cancel to begin configuring this screen afresh.
