I have a network in my College which is connected to the internet. How can I access a system inside this network from the internet (WAN)? I don't have access to the gateway of the system, so port forwarding is not an option. Is there any program that could run inside my computer (which is in the network) that could then connect to a static IP address on the Internet, reverse the connection, and make me able to use ssh/telnet to access the computer?
Edit:
I checked the duplicate question but still I am little bit confused.
Actually in my college I have ssh non root access to a system (192.168.1.5) from within the network
Is there anyway I can access that machine through ssh from the internet?
If ssh tunneling is an option how to setup that?
Can anybody explain step by step?
