Need to keep people on wireless AP in seperate vlans
We have a wireless AP that is connected in its own vlan that we allow consultants and guests to connect too. this allows them basic internet access and some email capabilities while at the same time protecting our network from any nasty stuff they might have installed on their machines. This has worked great for two years, but a couple weeks ago we had a consultant come in with a particularly nasty virus and he proceeded to infect all of the other guests that were on our wireless. This made all of our guests particularly angry :(
I am in need of a solution for this scenario. Is there some technology that keeps people on a wireless AP from seeing each other?
