Network Address Server Settings (DHCP)

The settings allow you to configure the Router’s Dynamic Host Configuration Protocol (DHCP) server function. The Router can be used as a DHCP server for your network. A DHCP server automatically assigns an IP address to each computer on your network. If you choose to enable the Router’s DHCP server option, make sure there is no other DHCP server on your network.

Local DHCP Server  DHCP is enabled by factory default. If you already have a DHCP server on your network, or you don’t want a DHCP server, then select Disable (no other DHCP features will be available).

Start IP Address  Enter a value for the DHCP server to start with when issuing IP addresses. Because the Router’s default IP address is 192.168.1.1, the Start IP Address must be 192.168.1.2 or greater, but smaller than 192.168.1.253. The default is 192.168.1.100.

Number of Address  Enter the maximum number of computers that you want the DHCP server to assign IP addresses to. This number cannot be greater than 253. The default is 50.

DHCP Address Range  Displayed here is the range of available IP addresses.

Client Lease Time  The Client Lease Time is the amount of time a network user will be allowed connection to the Router with their current dynamic IP address. Enter the
