How to configure TCP access like tcp://domain.com:3333?

Question

Domain Name System

Usually, domain and IP address are set in DNS and port 80 is assumed.
Using NGINX, I configure proxy_pass from port 80 (or 443) to the port I need.
There is a TCP server that is available at IP Address: 3333
I have a domain.com domain.
What needs to be done so that the TCP client can connect to the server at tcp://domain.com:3333 ?

Answer 1

DNS does not mean anything other than converting a name to an ip address. And what will work there at this address and which ports to listen to is your decision.
