proxy questions

[Justin Church]

I need to be able to proxy accounting requests that arrive with no 
User-Name attribute.  Is that possible?  I haven't been able to make it 
work.  Maybe I could insert a dummy User-Name pre-proxy and remove it 
post-proxy?

Also, I notice that when running in -X mode, the accounting-response is 
not relayed to the original client.  Works fine when not in -X mode. 
Here's a debug of a scenario where an accounting-request was proxied 
correctly; yet, the accounting-response is not relayed to the client by 
the proxy server:
