Oliver, you are my hero. The radius server is currently being used for dialup 
only and it was instructing the NAS to use a access-list, which did not exist 
on the C7200 BRAS. I temporary solved the problem with a simple "access-list 5 
permit any", now I need to fix the radius config.

I'd prefer 12.2S (which we were running before), but PPPoE is not available 
there... Regarding CSCsa47225, looks like we won't be affected because it 
appears the problem is only with multilink PPP, which we don't use.

Thanks for your help!
