Our church has a static IP address from the supplied router. We have an ethernet cable that runs from the router to another part of the building where a main computer is. I need to have 2 more computers have access to the internet. 1) Can I use a switch to supply a connection to the other computers? 2) One of the 2 computers is in another building 200 feet away. Can I use direct burial Cat6 to run to the other building and run it off the switch?
