You said only the 'file' protocol should be allowed (with --proto) so of
course HTTP won't work! (which is what is implied since you didn't specify
protocol un the URL)

Well, you're not using libcurl up there. You're using curl and it has no way
to only connect. curltunnel was a small attempt at something that never got
anywhere afair, I don't believe there is any promise anywhere of that being
functional.
