IPv6 tunneling control

The IPv6 tunneling control feature introduces new screens for tunneled traffic based on user preferences. By default, all tunneling traffic is allowed by the screens unless the external IP encapsulation matches the block criteria of any existing screen.

• GRE 4in4 Tunnel
• GRE 4in6 Tunnel
• GRE 6in4 Tunnel
• GRE 6in6 Tunnel
