Note: This option must NOT
be set on stations without a “public” IP address,
as otherwise it always produces an error and the GPRS modem is reset (the
use of DynDNS on stations without a public IP address is not meaningful in
any case).
•
Last Update : The time at which the last IP address update was sent to the
server.
•
Last response
: The server’s response to the last update. Positive responses
from the server are “good <ip address>” (IP address has been registered) or
“nochg <ip address>” (IP address did not change).
Note: A connection to the DynDNS server is only established after the GPRS
connection was (re-)established
. If necessary this can be forced by “resetting” the
GPRS connection.
5.11.4 Port Forwarding
Port forwarding for TCP connections via GPRS modem to network devices
(expecially cameras) that are connected to the LAN adapter of the LCom can be
configured here.
