Need help with clients configuration.

Hello all I am using Freeradius 1.1.0 on solaris 10 I am storing the clients information in the oracle database (table nas), my oraclesql.conf has following line: Readclients=yes In the nas table I have following entries: nasid=1, nasname=128.0.0.1/1, nastype=other, shortname=ems10 secret=testing123 This setup works perfectly fine on one machine, where as on another machine, the access request is ignored, saying it is from unknown client. The radius debug logs(with -X option) on both machines are the same. And in both cases, I sending the request from localhost. Does it have anything to do with the machine's configuration?? Can some one please help me?? -Vishwa.
