So, you’re working hard to keep your Linux server accessible across the web, but now you have more than one box on one line, and unfortunately, you need both accessible through SSH. What do you do? After searching high and low for any tips, tricks, or maybe even a solution, (believe it or not, they do sometimes exist on the internet), I found what I needed. And it’s so easy. Really. First of all, you need to change your port number on the Linux box that you would like to have forwarded. I did this using a web interface application, through which I could easily point and click to change the port numbers.
There were two reasons I chose to do this. First, I don’t easily have access to my physical box, so I didn’t want to lock myself out.

I chose an obscure port number that I would remember, but that wouldn’t be dead obvious to others. (I did this to add a layer of obscurity aided security.) If I’d had access to the box over command line, and remote management of the router, I would do it this way:
