We're a small company with 50 people. We have a lot of consultants and partners working on our site. The problem we have is that these people connect their laptop and have access to our internal net. I tried vlan and put them in DMZ but that's still not good enough. I want to know if Cisco has a product that when a person connects to our network, it will not give him/her an IP address unless they have a username and password. I was able to do this with Cisco Wifi back in 2001. A laptop users can see our wifi connect, then it asks for username and password. If they don't have it, it won't give an IP address. I hope this makes sense.
