Configuring the UDP Broadcast Redirector
In order to locate a server that can provide a particular network service,
many IP hosts rely on the use of LAN broadcasts to send UDP service
requests. The UDP port number contained in the broadcast request packet
identifies the service being requested. Table 3-1 shows the port numbers
and their corresponding requested services.

The UDP Broadcast Redirector enables you to configure any Routing
Services enabled device to forward the UDP packets that it receives as
LAN broadcasts, directly to the appropriate server. UDP service requests
that are sent as LAN broadcasts by clients of applications such as Host
Name, Domain Name, and Bootstrap servers, can be redirected to any
server on any network segment.
