If the total number of network nodes is greater than the range of available IP addresses, the DHCP server will run out of DHCP addresses, and some users will not get access to network resources. If this happens you can either (1) increase the Ending IP address (to the limit of 255) or (2) reduce the Lease Time. (see below)

Caution:

If you change the Start IP or End IP values, ensure the values are still within

 

the same subnet as the Routers' IP address. In other words, if the Routers'

 

IP address is 192.168.1.1 (default) and you change the DHCP Start/End IP

 

addresses to be 192.128.1.2/192.128.1.100, you will not be able to

 

communicate with the ADSL Router if your PC has DHCP enabled.

DHCP Lease Time

The Lease Time is the amount of time a network user will be allowed connection to the ADSL Router with their current dynamic IP address. The amount of time is in units of minutes; the default value is 3600 minutes (60 hours). In a situation where a number of casual users need to be connected for relatively short periods this default value is frequently set at a lower value.

DHCP Relay

DHCP relay allows requests and responses between a DHCP client and DHCP server to traverse the Router between the LAN and WAN subnets. The DHCP relay is positioned on the LAN (DCHP client) side. This will allow LAN DHCP clients to be assigned DHCP information (IP Address, Subnet Mask and Default Gateway) from a DHCP server on the WAN (usually at the ISP).
