Instruction on this side of the module I am sure there is no problem, before the experiment verified in the home, now I repeat this experiment in the school, found unable to connect, I show the IP address of the router management page for the school's LAN IP, I think the problem here, in the home experiment, IP connection module is the home of the network, the router set DMZ forwarding, can be connected to the PC based TCP server in the home, but for the middle and LAN IP thrust a thick stick, I really don't know how to deal with, I want to ask the great spirit, how can module sends data into my PC based on the TCP server, it is best to not to by other software, thank you ~!

Get the IP address of the 4 g module, and then sent via PC period of active connection request
