•Serve Dynamic WAN Clients
In addition to being a gateway, the Router is also an IP address server. There are three protocols it can use to distribute IP addresses.
•The first, called Dynamic Host Configuration Protocol (DHCP), is widely supported on PC networks, as well as Apple Macintosh computers using Open Transport and computers using the UNIX operating system. Addresses assigned via DHCP are “leased” or allocated for a short period of time; if a lease is not renewed, the address becomes available for use by another computer. DHCP also allows most of the IP parameters for a computer to be configured by the DHCP server, simplifying setup of each machine.
•The second, called BootP (also known as Bootstrap Protocol), is the predecessor to DHCP and allows older IP hosts to obtain most of the information that a DHCP client would obtain. However, in contrast, BootP address assignments are “permanent” since there is no lease renewal mechanism in BootP.
•The third protocol, called Dynamic WAN, is part of the PPP/MP suite of wide area protocols used for WAN connections. It allows remote terminal adapters and
Since no two hosts can use the same IP address at the same time, make sure that the addresses distributed by the Router and those that are manually configured are not the same. Each method of distribution must have its own exclusive range of addresses to draw from.
Go to the System Configuration screen. Select IP Address Serving and press Return. The IP Address Serving screen will appear.
