  OK, that's good.

  You update the inner-tunnel virtual server, and copy the User-Name to the outer request.  Perhaps in the "control" list, so that it doesn't affect anything else:


	update outer.control {
		&User-Name := &User-Name
	}

  Then in the default virtual server, you access &control:User-Name.

  The underlying issue is that the inner request is finished (and gone) after it returns an Access-Accept.  So you can't access it, because it's gone.  You have to manually save any information that you need.
