I have just been told that an external company will be renting an office in the school. They said they have their own servers, computers, printers, switches and cables so essentially their own network with its own IP range and subnet (I asked them for these details and they said they didn't know them)
I have been told they will need internet access
I obviously want them to stay completely separate from the schools network and only have direct access to the internet
What is the best way of doing this?
