Configuring a PPTP VPN connection on the Xiaomi Mi Router 4A router is straightforward — simply enter the server address, username, and password for your VPN subscription. However, it is important to note that PPTP is significantly less secure than modern protocols (such as OpenVPN or WireGuard) due to known encryption vulnerabilities. We recommend using PPTP only for bypassing geo-blocks or accessing non-confidential resources where maximum data protection is not a priority. For tasks requiring confidentiality (e.g., handling financial data), other solutions are preferable.
