Generic domain -> IP:PORT PROXY

Generic domain -> IP:PORT PROXY

I've some services on server with different ports (eg. ssh 4040,
PostgreSQL 4050, ...). Is there any way to say:
I specify "entry port" for servie (eg. 5432), where will listen
"something", that will know domain name and connects to service on
specified port:
pg.x32.cz:5432 -> proxy -> localhost:4050
mc1.x32.cz:25565 -> proxy -> localhost:25566
mc2.x32.cz:25565 -> proxy -> localhost:25567
....
