This can ensure transmission security, but also flexible switching between different regions of the IP address, especially suitable for the need for long-term stability of the network environment of the old iron.

Windows system configuration:First, open "Network and Internet Settings", find "VPN" to add a new connection. Select L2TP/IPsec as the type, and fill in the server address with the gateway address you got from ipipgo.

The cmd command to check the connection status
ping your proxy server IP -t
netsh interface show interface
Mac system configuration:Create a new VPN in System Preferences and select the L2TP over IPSec type. Don't be stupid and fill in the server address on the ipipgo website, but fill in the dedicated server address they provide. In the Authentication settings, check the box "Send all traffic through VPN" so that all network requests go through the proxy channel.
