Proxy load balancing

Hello,
I'm working to setup a proxy load balance to 3 production RADIUS servers
from a CentOS server running freeradius 2.1.12. I believe I have the
proxy.conf file setup correctly but there seems to be no load balancing.
All the requests are going to one of the three servers. I have attached
the proxy.conf file and also the radius debug. I don't see any errors, it
just appears the client-balance is not working. Clients are using MAB and
are matching the NULL realm. I have looked through all the past posts and
can't seem to find an answer. Am I missing something in my configuration?
Thanks.
