3. Using the Web Interface

 

4. The DHCP server is enabled when “Enable DHCP Server” is selected. If you 

enable it:

— Specify a Start IP address. The Start IP Address is where the DHCP 

server starts issuing IP addresses. This value must be greater than the 
router's IP address value. For example, if the router's IP address is 
192.168.1.1 (the default) than the Start IP address must be 192.168.1. 2 
or higher. 

— Specify an End IP address. The End IP Address is the last address the 

DHCP server can issue. The ending address cannot exceed a subnet limit 
of 254. The maximum IP address for a router using the default address is 
192.168.1.254. If the DHCP server runs out of DHCP addresses, users 
will not get access to network resources.

— Specify a Lease Time. The Lease Time is the amount of time a network 

user will be allowed connection to the Router with their current dynamic IP 
address. The amount of time is in units of seconds; the default value is 
3600 seconds (1 hour).

Note: If you change the start or end values, make sure the values are still within 
the same subnet as the modem's IP address. For example, if the modem's IP 
address is 192.168.1.1 (the default), and you change the DHCP Start and End IP 
addresses to be 192.128.1.2 and 192.128.1.100, you will not be able to 
communicate with the modem if your PC has DHCP enabled.

In addition to the DHCP server feature, the modem supports the DHCP relay 
function. When the modem is configured as DHCP server, it assigns the IP 
addresses to the LAN clients. When the modem is configured as DHCP relay, it is
