How do I configure my router so that any pc that connects to any of the 4 local lan ports can access the Internet but none of the local PCs can access each other?
I've tried using "advanced filtering" on my Actiontec MI424-WR router and specifiying filters to drop packets that had a source or destination address matching any of the PCs on the local lan, but that did not prevent those PCs from talking to each other (using Microsoft remote desktop, remote networking where Windows Explorer could see files on one local pc from another local pc, etc, etc).
I have the impression that that kind of filtering only operates on packets going to/from the internet, not to/from local PCs to each other.
I also tried putting each local PC on the lan on its own LAN, but that did not help either.
I know I can block sharing, etc on each local PC, but I also want to block the local PCs from talking to each other by using the firewall in my router.
How do I do that?
Thanks tons & tons!!!
My guess is you'll need a business class router to perform this task.
So you'll have to block access from each computer at each computer in the firewall setting depending on the OS.
I'm trying to think of some IP configurations to assist in this and nothing quick really comes to mind.
I suppose you could get 4 additional routers and put 1 computer behind each router....that would block access for sure.
