How do I enable "Tunnel Crack" protection in SoftEther VPN Client Manager? What is it, and how do I use it?
"Tunnel Crack" is a VPN protocol designed to secure connections when using untrusted or potentially malicious public wireless local area networks (WLANs). When this feature is enabled, the system helps block threats, prevents connection drops or slowdowns, and ensures that local network traffic—which remains outside the VPN—is unaffected. This feature functions when a VPN is in use on both a device and a gateway router, allowing both to share the same VPN connection. How can I enable Tunnel Crack protection in the SoftEther VPN Client on Windows? 1. Open the SoftEther VPN Client Manager program on Windows 10/11. Note: If you are currently using Easy Mode, switch to Normal Mode. 2. In the navigation window, go to Tools > Options. 3. Advanced security: Check the box labeled "Enable TunnelCrack protection," then click OK.
