What do you think of the following questionling?
I have a wireless sensor board, it has a GSM/GPRS module with TCP/IP stack. Now my server (MQTT ofc) will be hosted on my laptop which is behind my router, so I cannot access it directly. I know that I can listen on a specific port, and forward all incoming data to my server by the router. There are a lot of resource on the web about it, but few are complete enough and opening a port behind my router is risky. So with some research work as well, can I ask about the steps of this setup?
