As far as I know, radius clients (which is what Radiator is when acting as a
proxy) use high source port numbers when sending requests. The only time we
have seen something different (ie. broken) is with some versions of GRIC on NT,
which don't reply to the source port as sent in the request.
Someone else on the list may have other comments.
