@MichaelHampton the question didn't hide any information before it was put on hold, the edit I made weren't to hide anything but to move the focus out of the raspberry pi since the question got on hold for this while it's irrelevant.

It's debian/Raspbian.

@MichaelHampton I tried to hide reference to the PI after it was marked as off topic for being a RaspberryPI question (which isn't), not the other way around.

Because the question is about networking in general and not about the raspberrypi. I'd have something else than a PI I'd be asking the same question.

Routing/Network issues not related to the hardware.

Sadly it seems on server fault it's better to hide important information to get actual help. If I had a standard network I wouldn't be asking questions.

There removed any reference to the raspberrypi and replaced it by kiosk.

@HBruijn yes I see that but the question is still on-topic because technically the problem I have isn't related to the PI hardware. We had problem yesterday with the USB randomly disconnecting but that's not the Issue I was asking help for.
