Port 23 should be forwarded on the firewall to make the internal FTP server accessible from the Internet. Port 23 is the default port for Telnet, a protocol used for remote login and command execution on a remote computer. However, it is important to note that Telnet is an insecure protocol and is typically replaced by SSH (port 22) for secure remote access. Therefore, it is more common to forward port 22 for SSH access to an FTP server.
