Thanks calmh! I finally made it works, your message put me on the way. You can use stream feature of nginx to do this (http://nginx.org/en/docs/stream/ngx_stream_core_module.html)
I finally did this configuration: tcp://domain.me:9000 -> 192.168.1.1:22000
The final result on Nginx Proxy Manager if someone is interessted to do the same:
