Well, this school year, I'm going to a new school in which bringing your laptop is
required. Since I do a lot of hosting for various games, I've obviously port forwarded my internet and configured my static IP. But, the problem is, I can't leave those settings on when I go to school, since that IP has a 95% chance of already being in use on their network.
Are there any programs that can do this automatically, with the click of a button? Basically, I'm looking for something that can save my settings and toggle it on and off with only a few clicks. It gets rather annoying to have to go type everything in (even though I've memorized them by now), and sometimes I forget.
If you don't know what I'm talking about, it's this window (before and after):
