F.3 The Importance of Transparent Operation
In some situations, the remote site may be nothing more than PC's that need to be connected to a
central office for E-mail, File Transfers, or Internet access. In these cases, it's often desirable to
have all of the network IP addresses assigned dynamically on an as needed basis by a DHCP
server. Because the EEI can be configured to work like a bridge and not like a router, the DHCP
Requests and Responses required to bring the remote PC's online, are passed transparently across
the satellite link. In addition, the four-port switch interface on the standard 10/100 EEI allows
small remote networks, as illustrated in Figure F-2, to be set up without adding external switches
or hubs.
