6.1.4 Dynamic IP registration
This feature allows the modem to report a message to a user-configurable IP address every
time its WAN IP address changes.
It is useful when the cellular account is associated with a dynamic IP address. Since the WAN
IP address will be changing regularly, it will be impossible for the user to know which WAN IP
address is assigned to the modem. With Dynamic IP Registration enabled, the modem will
notify a remote server of the new WAN IP address as well as the modem’s ESN in hexadecimal
format. The IP Registration packet can be sent using either TCP or UDP.
To configure Dynamic IP Registration, navigate to
CONF (Modem Configuration) >
General
, and set the destination IP address and port. The registration timer is a value (in
minutes) that controls how often the modem should report its IP to the server. If it is set to
zero, the modem will report its WAN IP address upon boot-up or upon acquiring a new IP
address from the cellular carrier after losing the cellular connection. If it is set to a value
between 1 and 65535, then it will report its ESN and WAN IP regularly at the specified
interval.
