Router Functions

The DHCP and NAT functions of the Router allows the network manager to more

easily manage IP addresses and subnets, and enhance network security by

presenting only one global IP address to the Internet. This section discusses how

to use these conventional routing functions.

DHCP

The Dynamic Host Configuration Protocol (DHCP) allows the Router to assign IP

addresses to all properly configured hosts on the network. Dynamic IP

assignment alleviates the need for the network administrator to maintain and

monitor IP address assignments and simplifies IP use because IP address are

automatically assigned when a station powers-on. Click on the DHCP

Configuration button to see the DHCP menu.

IMPORTANT: If you use DHCP to set your local IP addresses, the IP settings of all

stations on the network must be either manually configured to 0.0.0.0 or, select the

“Obtain an IP address automatically” option under the TCP/IP Properties tab in the

Network menu. See the Configure the Manager PC section at the beginning of Chapter

4 for more explicit instructions.

DHCP Configuration Window

In the DHCP Configuration window you define the following:

Start IP Address

This is the base (starting) address for the IP pool of unassigned IP addresses.
