The "websocket proxy" is something completely different from what
you are looking for. It's to proxy the Websocket protocol
connections - that is, to proxy HTTP/1.1 requests with protocol
upgrade.

To proxy arbitrary stream sockets, use the stream module. See
here for details:

http://nginx.org/en/docs/stream/ngx_stream_core_module.html

Note that it's only available in nginx 1.9.x.
