I am trying to send a push message from the server to HL6528. One way to do this is to initiate a TCP connection from the server to a listening port of the modem. The problem here is that i can not get the ip address of the modem in order to initiate the tcp connection. The telecom carriers are not revealing a public ip address only through their network.
I would appriciate any help on this on how to contact the HL6528 from the server.
