  Hi,

It can translate back and forth in many cases, but not all. Example: at 
some point, your Diameter server wants to send Filter-Rule AVPs to 
restrict the client's access to some resources. The total length of all 
filter rules which the Diameter server adds to the reply is 4100 Bytes 
long. RADIUS messages can't exceed 4096 Bytes. Translation will fail. 
QED. :-)

(BTW, I looked up whether RFC4005 discusses the 4096 bytes boundary, but 
Ctrl+F for "4096" didn't give any match at all. I assume it has to be 
somewhere... anyone care to hint me at the appropriate section?)
