It sounds like you may want to use the nginx "stream" module, which has
documentation and some examples at

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

Note that you will probably need to distinguish your back-end servers
by TCP or UDP port, because the nginx server will not (in general)
know which hostname the client used originally; nginx will know which
IP address and port it connected to.

Good luck with it,
