This sounds like a job for private VLANs. According to the documentation, private VLANs can restrict traffic between machines on the same VLAN, as long as they are in different ports.
Ken DISCLAIMER: Book knowledge only. Still preparing to try it in the real world. >>> "Ron" 03/05/03 08:25PM >>> I have need to put public access machines on the same pipe as my private network. I also have need for each of the public machines not to talk to each other. Is there a way to keep all ports connected to public machines from talking to each other except for one port connected to a printer and one port connected to a router going to the Internet? Maybe all separate Vlans? All of my private machines can talk to each other, but not the public machines, and will be going over the same Internet pipe. I will probably be using Cisco 3550-48-EMI switches. Can anyone get me an easy way to do this one?
