HBruijn already explained why the second question has been deleted. 

Both questions *are* [off-topic](http://serverfault.com/help/on-topic) on SF because they 100% deal with `consumer workstations or networking`. Regardless of how you use it, you use a residential consumer internet connection in your home and on top of that, you want to connect to a RasPi, which we would consider off-topic even in a company network and usually close questions regarding it with the following reason: 

> Questions should demonstrate reasonable business information technology management practices. Questions that relate to unsupported hardware or software platforms or unmaintained environments may not be suitable for Server Fault - see the help center. 

We don't consider to be using an RPi as actually reasonable for any business purpose due to its severe shortcomings in hardware design and I just cannot see why anyone would want to use this kind of hardware in a residential network to provide "professional services" instead of just firing up a 5$ DO instance that does the same job better. 

Lastly, as a university is in the business of research and education (even as a nonprofit), this is clearly on-topic. Incidentally, I am a full time university sysadmin and I even use RPis at work, but they are for completely non-critical tasks and if I had ever any questions regarding them, I would ask at [SuperUser](https://superuser.com), [Unix&Linux](https://unix.stackexchange.com) or [rpi.se](https://raspberrypi.stackexchange.com).
