  The debug log should show *why* that's happening.

  It's a ridiculous thing to do.  That seems to be the habit with RADIUS.

  The server doesn't really care about the contents of the packets it's proxying.  They're all the same.

  So something is different in your configuration, and treats the packets differently.  What is it?  The default configuration doesn't do anything special with proxying accounting "on" versus "start" or "stop".

  If there's nothing special in the config, see the debug output for what's going on.
