Are you able to ping the server from the PIX ?

are you able to verify the ports on the radius server ports 1812,1645

also make sure the key on both sides are same. In case you are using a self created network devices group in ACS, make sure you are using the group key in NAS and not the device key. Group key will take precedence.

i can ping that radius server from ASA, how can I verify the posts from radius?

i can sure that the shared secret key is same as the key in aaa- server firewall.
