HBruijn already explained why the second question has been deleted.
Both questions are off-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 an 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, Unix&Linux or rpi.se.
