Setting VPN Interface Priority in Windows 10
When using the Shrew Soft VPN client on Windows 10, it is important to configure the VPN interface priority to ensure a stable connection. By setting the VPN interface with the highest priority, you can ensure that it takes precedence over other network interfaces. This can help prevent any routing issues and improve the overall performance of your VPN connection.
To set the VPN interface priority in Windows 10, you can use the Set-NetIPInterface command in PowerShell. The metric value determines the priority, with a lower value indicating a higher priority. By setting a lower metric value for your Shrew Soft VPN interface, you can make sure that it is selected as the primary interface for routing and DNS server selection.
By configuring the VPN interface priority, you can also prevent DNS leaks. DNS leaks can occur when the VPN interface does not take precedence over other network interfaces, resulting in the use of non-VPN DNS servers. To ensure a secure and private browsing experience, it is essential to set the VPN interface as the highest priority.
Steps to set VPN interface priority in Windows 10:
- Open PowerShell with administrative privileges.
- Run the following command: Set-NetIPInterface -InterfaceAlias “Your VPN Interface Alias” -InterfaceMetric 1
- Replace “Your VPN Interface Alias” with the actual alias of your Shrew Soft VPN interface.
- Press Enter to execute the command.
By following these steps, you can ensure that your Shrew Soft VPN interface has the highest priority in Windows 10, improving the stability and reliability of your VPN connection. Remember to restart the VPN client after making these changes for the new priority settings to take effect.
