Section 6: IP Networking Features
As mentioned previously, the modem acquires an external public or private IP address (WAN
IP, or Wide Area Network IP) from the cellular network upon establishing a connection. A
remote user can communicate with the modem or a host behind the modem, however the
appropriate port-forwarding and LAN IP configuration settings have to be set on the modem.
Some carriers disable remote access as a security measure. If you are certain that
the modem is on the cellular network (i.e., it has acquired a WAN IP) but you
cannot reach it remotely, ask the carrier to allow incoming IP data traffic on the
required port. Read the Troubleshooting appendix for more details.
