IPv6 support

ON / OFF Set the switch to ON to enable IPv6 support on the firewall.
To find out which modules support IPv6 and what changes have been made to the various modules in the administration interface, please refer to the section Enabling IPv6 in this guide.

WARNING
As this action is irreversible, you are advised to back up your configuration before enabling support. To revert 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 reset button if your appliance has one, or by using the “defaultconfig” CLI command in console mode.
