AAA with IAS as RADIUS Server

[sikarius]

Hi Everybody !!

I have a "problem" with my IAS Server. I want to register the accounting information that my routers make. I active the aaa service in my cisco router with

aaa new-model
....
aaa accounting network default start-stop group radius
....
radius-server host 192.168.168.192
radius-server retransmit 3
radius-server key radiuskey

I use IAS as RADIUS Server. I have the log of the authentication of my users but nothing about accounting. I debug my router and it send the accounting information but my IAS seems that not logged

Could anyone help me?

Thanks a lot

PD: i use a VPDN to connect my users to my intranet. I active the vpdn aaa nas-ip-address vpdn-nas and vpdn aaa nas-port too.
