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.
