PEAP, Freeradius and Cisco AP 350

Wed Aug 31 23:40:15 CEST 2005

I managed to get it working, the machine here running freeradius has 2 ip 
addresses. I had noticed in another message on the list, that can be 
problematic. I set freeradius to bind to a specific IP and it light right 
up, go figure heh. I do appreciate the respone though. I spent a good 5 1/2 
hours before posting to this list I am kind of embaressed to find out it was 
a simple IP address problem, sorry for the bogus posting.
