[2.1.8] No actions performed on (own) received accounting packets.

Hello List, I seen to have a small issue. I have 2 running Freeradius 2.1.8 servers. I have set up proxying via the detail file readers - but for some strange reason, when the packet arrives at the remote server It says that it has received the Accounting-Request but then does no processing. The strange thing is, is that I have accounting packet proxied to me from my up stream provider and they are being processed as expected. Where should I look to see why the server is not processing the Accounting-Request. Kind Regards, Etienne
