Which ports should be opened for FTP access?

I have set up an FTP server on a Windows 10 Pro machine
If I access it locally with ftp://192.168.1.151/, it works perfectly.

If I access it from another computer, it works only when the firewall is disabled. I added a firewall rule to open ports 20 and 21, but it still does not work:

If I use the rule to open all ports, it will work, so this is a port opening issue.

What ports should I open to allow another computer to access this FTP server?

    Something here may help.

    IIS/FTP is not currently supported here on QnA. I'd try asking for help in dedicated forums here.
