Is there a way to force nginx to proxy rpc?

Question

Nginx

Actually, subject.
I'm reading similar questions now, but they have been going on since 2009 and even earlier ...
And is there really no module that would allow this?
The task is simple - to make outlook work outside the local network.

Answer 1

NGINX Plus R6 (and open source NGINX 1.7.11 and later) support RPC over HTTP traffic with the unbuffered upload feature, which you configure with the proxy_request_buffering directive.
those nginx can do.

Answer 2

iptable will help you,
but nginx is not needed for this
