What is the difference between the Cloudnet CLI Helper telnet function and ordinary telnet?

The telnet function of the Cloudnet platform is different from the telnet function of ordinary devices. The Cloudnet telnet device transmits telnet packets through the tunnel between Cloudnet and the device.

If the firewall does not allow telnet-related ports, the CLI Helper function of Cloudnet can be used normally.

But for the device, the telnet function of the Cloudnet CLI Helper is the same as the common device telnet function perception, which is a terminal telnet to the device.
