Thank you all for your helpful suggestions. Below is the configuration that did what I wanted: to block all but a select list of MAC addresses from accessing my network through a wireless access point. The configuration below allows me to add MAC addresses as my users buy NICs. Keep in mind this is a temporary solution until I buy a Cisco Aironet 1200, which people have told me has some of this functionality built in.

Has anybody done it before? Here's what I'm trying to do: I've got a wireless access point that lets just anybody join. I want to put a router upstream to block all but a limited number of pre-defined MAC addresses. Any thoughts? _________________________________________________________________ Commercial lab list: http://www.groupstudy.com/list/commercial.html Please discuss commercial lab solutions on this list.
