Configuring Network Settings
 
DHCP 
DHCP, the Dynamic Host Configuration Protocol, describes the means by which a system can connect to 
a network and obtain the necessary information for communication upon that network. Do not change the 
default DHCP Configuration settings unless directed by your ISP.  
Note: All addresses must be entered as an Ipv4 subnet mask in dotted-decimal notation (for example, 
255.255.255.0). 
To configure the DHCP feature: 
1. Select Setup>DHCP from the left navigation pane of the Web interface. This displays the “DHCP 
Configuration” window. 
 
2.  Select one of the following: 
•  Enable 
The Router will operate as a DHCP server to handle DHCP requests received from connected 
LAN-side hosts (DHCP clients). The DHCP server does not serve WAN-side DHCP clients. 
 
The DHCP operating mode defaults to Enable, and the system auto-generates the current IP 
address range, IP netmask, and default router. Do not change these default settings unless 
directed by your ISP.  
•  Disable 
Disables DHCP. If you are using a static IP address, you may need to disable DHCP and enter 
different addresses in the text boxes. 
•  DHCP Relay 
Instead of getting an IP address from the Router, the IP address is gotten from the computer as 
defined in Relay IP. Used when DHCP information is received from a DHCP server on the WAN 
side. DHCP requests are forwarded to the WAN side to Relay IP, and DHCP responses are 
forwarded back to the LAN side.  
3. In 
Start IP Range, enter the beginning IP address of the range of addresses from which the DHCP 
server will lease to requesting DHCP clients.
