Remotely accessing Raspberry Pi from internet

Hello,

I plan to make a remote device using the raspberry pi and a few cameras that a user can login through the internet. I want the device to be plug and play, such that the user can plug in the cameras to the raspberry pi, power on the device, login to the home internet connection and after this the device can be accessed from the internet.

Most instructions that I have googled, suggest port forwarding, but this is not an option as it requires tweaking the router settings that would be an extra load on the user end.

I came across weaved IoT kit that enables remote connections to networked devices through various ports over the internet. However, this service requires commercial licensing and I want to start off with something free, if possible.

Please suggest some ways.

Thanks in advance.

You'll need to look at creating an egress solution rather than ingress.  The Weaved IoT Kit uses a cloud based server to facilitate communication.

In other words, your raspberry pi would need to connect outbound over a common port (i.e. 443/TCP) to a server you control on the Internet.  "Inbound" connections to access your raspberry pi would actually connect to the same cloud server hosted on the Internet and "forward" or "translate" the access requests back through the channel the raspberry pi had previously established.

Here's a resource showing how to do a reverse ssh tunnel:

Obviously you can skip over the "covert" aspects of this tutorial and just try to understand the concepts of whats taking place.

If SSH won't do the job you're looking for, you most likely will need to code your own solution, which will be a lot more expensive/involved than just purchasing the Weaved IoT Kit.

Isn't there someway I could design/develop an ssh client with native android ui that logs in to the pi, and there after the login, it allows us to run various scripts and programs through buttons on the UI?
