Is there a way that I can restrict (at the physical port) access to the internet on 3Com 4400 switches?
For instance, physical network has about 100 ethernet ports available, with only about half of them actually connected to anything. I have been able to restrict web access at the router for a group of machines that have no legitimate need to surf the web. (Those machines are setup with static IP's; most of the rest of the network which is DHCP.) However, if someone brings in a laptop from home, all they need to do is plug in to one of the existing ethernet jacks, and they will be given an IP address from the DHCP server, and then they are free to do as they please.
I know I can disable the unused ports all together, but can I in some way just restrict outgoing http:80
