Overview
VirtualShield offers IPv6 Leak Protection by disabling all IPv6 traffic while connected to our VPN, thus providing you with a guarantee that no Internet traffic leaks out over your regular connection while the VPN is active.
All of your regular (IPv4) traffic will be encrypted and routed through our secure network, before it reaches the other end. Alternatively, you can permanently disable IPv6 traffic manually from your System Settings.
Windows
If you are using an IPv6 address to connect to the internet, it will be disabled automatically while you're connected. If the VPN disconnects for any reason, your IPv6 traffic will be immediately restored.
As long as IPv6 Protection appears Active when you open the app, it means you're fully protected. You can surf the web and use all of your apps just as you would normally.
Alternatively, you can permanently disable IPv6 traffic from your System Settings. Just be aware this will impact your regular connection, and some components might not function.
