Easily open your router’s configuration page with rCon
Tweaking your router’s settings is easy, at least in theory: just enter its IP address into your browser, log in maybe, and browse the configuration pages to access whatever you need.
Of course you’ll need to know the appropriate IP address, though. That’s not always obvious, and while you could do the IPCONFIG /ALL thing to locate your internet gateway address, that’s not exactly obvious to everyone, either.
