Why is 22 the default port number for SFTP? Is there any specific reason for this?

SFTP (SSH file transfer protocol) uses port number 22 by default, but can be configured to listen on different ports.
or go to Control Panel > System and Security > Windows Defender Firewall1 > Advanced Settings > Inbound Rules and add a new rule for port 22.
SFTP runs over an SSH session, usually on TCP port 22. It has been around since late 1990s. The acronym actually stands for "SSH File Transfer Protocol".
By default, port 22 is open on all IBM StoredIQ hosts. The port is used for Secure Shell (SSH) communication and allows remote administration access to the VM. In general, traffic is encrypted using password authentication.
It's the default SSH port and SFTP is usually carried over an SSH tunnel.

Why is 21 the default port for FTP? Or 80 the default for HTTP? It is a convention.
