IPv6 Support

Enable IPv6 support on this Firewall

Enables support for IPv6 on the firewall.


To find out about the scope of application of IPv6 support and changes to the various modules in the administration interface, please refer to the section Enabling IPv6 in this guide.


As this action is irreversible, you are advised to back up your configuration before enabling support. To go back to IPv4 support only, you will need to reset your configuration to its factory settings before you can restore the backup of this configuration.  Reset your configuration by pressing the dedicated button if your appliance has one, or by using the “defaultconfig” CLI command in console mode.
