I have Cisco 1230AP's providing access to my LAN for laptop users. The encryption is via WPA. I now need to setup my guests/visitors - keeping them away from my LAN and internal network and they can only (guest) use internet but all employs should use intranet & internet . How can I do this? Do I just setup a 2nd SSID or do I need to implement some type of VLAN? My switch is 3750 managed AND my internet is terminet on firwall.Thanks for your help...
