Hello, Habr. Many people who purchase a clock or a weather station have probably seen the Radio Controlled Clock or even Atomic Clock logo on the packaging.

Hello everyone, this is my first experience on Habr. I want to write about non-standard methods of managing network equipment in external networks. What does non-standard mean: in most cases, to manage equipment in an external network, you need: a public IP address.
