Every UDP multicast group must be bound to a network IP interface address. The RAP installer refers to this value as the local interface.
If you plan to perform a Custom or Express installation, ask your Network Administrator to determine which network interface to use, and record this information on the installation worksheet. Use this value for all local interface fields during installation.
If you intend to perform a Demo install, you can skip this step because the installer assigns 127.0.0.1 as local interface value.
