Note: The Raven XT does not provide advanced routing required by

one-to-many (several devices connected to one port). If you need to

have more than one device connected to the Internet through your

Raven XT, you will need to have a router connected to the modem.

The modem would provide the one-to-one connection to the router

with the router configured to provide a broader NAT service to the

other devices connected to it.
