Firewall

If the global firewall is enabled for IPv6 interfaces, you can disable the firewall for an individual tunnel interface here. To enable the firewall globally for all interfaces, select IPv6 firewall/QoS enabled in the menu Firewall/QoS > General .

Anmerkung: Disabling the firewall globally means that the firewall is disabled for all interfaces, even if you enable this option.
