When added in the "inner-tunnel" server, this block has no effect on the 
content of the Access-Accept packets (as shown by radiusd -X). I've 
tried adding a similar line to the outer server to statically set the 
outer ID and there it does indeed get put in Access-Accept packets. My 
NAS does indeed remember it and use this name for accounting.

So the question is, why does it not work in the inner-tunnel?
