Radius wont Authenticate Default Users

Question

I am using free radius on ubuntu 12.04 LTS. 
The AAA configs I have, I  used on all of my Layer 2 devices, and it works successfully, however I can not get users to authenticate on a Layer 3 device.... here is some info... I can ping to and from my server, also I have rules on the asa 5510 allowing devices to talk to the radius server... as well as an access-list permit on the router....what am I missing.

Answer 1

It seems that your radius server is not listening on udp 1812 port. Try to use 1645 and 1646 port for radius authen/author and accounting respectively and also apply firewall rules to allow traffic on these udp ports.
