You can use this article to allow or whitelist only a specific IP address on a port.
If you wish to limit access to your Remote Desktop Protocol port to only your local IP address, you can easily do so. This will ensure that only your local IP address can connect to your server and all other IP addresses are denied access.
You can also grant access to the same IP address to multiple ports on the same server. Providing access from a single IP address to multiple ports on the same server is possible. You can improve the security of your servers by limiting access to specific IP addresses.
