This is what you said: "...a RadSec to RADIUS gateway involves
terminating TCP, TLS, and forwarding the contents to RADIUS. If this
isn't RADIUS, then by the same standards, any HTTPS to HTTP proxy isn't
doing HTTP." A Diameter to RADIUS gateway involves terminating TCP (or
SCTP), TLS, and forwarding the contents to RADIUS. If you really think
that this is different from your HTTPS->HTTP example, perhaps it's
because you are conveniently ignoring the fact that HTTP is only defined
over TCP. However, one could just as easily argue that HTTP != HTTPS,
given the need for different port numbers...

I really don't know how that is relevant. Dropping down a layer or 2,
the same protocols can be carried by both Ethernet & ATM. Are you going
to claim that they are somehow compatible (backward, forward or

I know that you have read RFC 2865 (probably more often than I), so you
know that there is no such thing as a standard "RADIUS application
protocol", defined w/o regard for the underlying transport.

I can't find any mention of IPv4 in RFC 959; it does mention TCP,
however. Would FTPoUDP also be FTP? How would FTP & FTPoUDP
interoperate? These questions seem much more to the point, I think.

One more time: the version of IP being used is transparent & therefore
irrelevant to FTP. UDP transport is forever enshrined in RFC 2865,
however; maybe that's a bad thing, but it's true nonetheless.
