Caution: If you want to connect remotely to your Raven XT using
TCP/IP, the IP address given to your modem by your cellular provider
cannot be a private or internal IP address (such as a custom APN or
special private network Data Link) unless you are on the same
network or inside that network’s firewall (such as with frame relay).
