Duplicate IPs for Radius Clients with different secrets

Okay. What you need to do is set ips in the client configuraiton file
for each of the APs that is going to be authenticating by using their
external ip address, which is where the connection will appear to come
from to freeradius. do a freeradius -X and it should be quite
explanatory, when you try to connect through an AP to it.
