actually i am authenticating a user using openser and opendiameters NASREQ application as the client and server.at present the openser is sending the all needed avp's to opendiameter client.i can see all the avp code and avp data on the client side. my problem is that the on the diameter server side the avp,s are not transferred by the client. the client is giving something like (6372|1698151312) Acceptor peer failed establishing state [3003], closing i am confused about it.by reading some drafts i came to know that the error is due to realm mismatch.but i am sending the same realm as the opendiameter's realm.in both the cases it is [bhargav.s]. before i sent the avp's from openser side there was no such problem showing on the client side.if anybody know the solution please help me regards bhargav.b(a)renovau.com
