In the process of setting up a 7206 to terminate ADSL connections, using a Radiator (Radius) server for auth.
The test ADSL connection appears to authenticate successfuly, but then disconnect immediately, then attempt to authenticate again.
I am seeing the following in the 7206 logs:
Jul 13 08:13:57.335 aest: AAA/AUTHOR/VPDN/LOCAL: Looking for tunnel dsl.datafx.com.au
Jul 13 08:13:57.335 aest: AAA/AUTHOR/VPDN/LOCAL: tunnel dsl.datafx.com.au doesn't exist
Jul 13 08:13:57.335 aest: AAA/AUTHOR (2818497300): Post authorization status = ERROR
and

Then I see the connection est. then a nosess:

Have the following on the 7206 (Multiple vpdn-groups are defined):

I'm certain I am missing something vital in the radius config...
Any assistance is greatly appreciated.
