I am new to setting up ssh server. I wanted to set up my desktop as a server at home so that I can run programs on my desktop remotely, after installed a few necessary packages, I could have my laptop that is in the same wifi network connect to my desktop but it will not connect once it is outside this wifi network.
After some search online, I found this page very relevant: Configure OpenSSH server and router to accept SSH connection over internet? so the suggestion is to configure the router and make a port forwarding(if someone could explain the concept in simple terms would also be great), however I do not have the access to the router(at least for now) as I am renting the place and the router was set up by someone else. I was just wondering are there any options left or do I have to have the access to configure the router?
