As additional information, Bitcoin Core use port 8333 by default. Theoretically you can change the port number and other node still can connect to your node, but AFAIK there's no strong reason to do that.


Have you visited the homepage, scroll down to "Join the Network", enter your IP address/port and click "Check Node"? If you didn't do that, it'll take some times before bitnodes discover IP address/port of your node through another way.
