DHCP

A DHCP (Dynamic Host Configuration Protocol) Server a u t o m a t i c a l l y assigns IP addresses to each computer on its network. Unless you already have one, you should set the Router up as a DHCP server. This is done on the DHCP tab, shown in Figure 5-9.

•DHCP Server Click the Enable option to enable the Router’s DHCP serv- er function If you already have a DHCP server on your network, set the Router’s DHCP option to Disable.

•Starting IP Address Enter a numerical value for the DHCP server to start with when issuing IP addresses.

•Number of DHCP users Enter the maximum number of PCs that will require IP addresses assigned by the Router. No more than 253 computers can be used. In order to determine the DHCP IP Address range, add the starting IP address (e.g., 100) to the number of DHCP users. By default, as shown in Figure 5-9, if you add 50 users, the range or IP Addresses will be 192.168.1.100 to 192.168.1.149.

•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 amount of time, in minutes, that the user will be “leased” this dynamic IP address.
