Network Settings tab

IPv6 support

ON / OFF Set the switch to ON to enable IPv6 support on the firewall.
To find out about the scope of application of IPv6 support and changes to the various modules in the administration interface, refer to the chapter IPv6 support in this guide.

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.

Proxy server

ON / OFF Set the switch to ON to enable the use of a proxy when the firewall accesses the Internet for Active Update and License Update services.
Server This field makes it possible to specify the object corresponding to the server that the firewall will use as a proxy.
Port This field allows specifying the port used by the firewall to contact the proxy.
ID This field allows defining an ID that the firewall will use to authenticate with a proxy.
Password Define a password that the firewall will need in order to access the proxy server.

DNS resolution

List of DNS servers used by the firewall

DNS servers allow the firewall to resolve (find out IP addresses based on a host name) objects or hosts configured in “Automatic” DNS resolution.


When you click on Add, a new line will be added to the list of DNS servers. Choose an object from the drop-down list or create a new one.

Delete Select the DNS server to be deleted and click on Delete.
Do note that if you delete all the DNS servers defined in the table, the firewall will then use Root DNS servers. These servers are found in the DNS configuration file (/usr/Firewall/Data/dns).
