Hiya The small charity I work for has set up a satellite office in a city pretty far away. We've rented an office there, and have just moved in 3 staff there. The problem is that all the other offices in the building can see our computers on the building network, and we can see theirs too. As some of our work involves supporting people with legal and social issues, there is an issue of security and confidentiality here. For our work, we have to be able to share our files between our 3 computers, and send files to our networked printer. I've spoken to the building manager who asked the building technician about the issue. The response I got was that we could pay for a 'WAN ethernet port' which I suppose will go on the rackmount servers / switches for the building. To be honest, this doesn't really make much sense to me. Can you help?
