What is VPN on the Xiaomi router?

VPN stands for Virtual Private Network. It's a technology that creates a secure and encrypted connection over a less secure network, such as the Internet. VPNs are commonly used to protect sensitive data, maintain privacy, and provide anonymity while browsing the internet.
For your reference, here are some key features of the VPN:
1. By connecting to a VPN server, your internet traffic appears to originate from the VPN server's location, rather than your actual location. This masks your IP address and provides anonymity while browsing the Internet;
2. VPNs can be used to bypass geo-restrictions and access content that may be blocked in your region. By connecting to a VPN server in a different country, you can access websites and online services as if you were physically located in that country;
3. VPNs are commonly used by businesses to provide remote employees with secure access to company resources, such as files and applications, from anywhere in the world.
