Network objects let you enhance security and optimize performance for devices behind the firewall. You can use these settings to configure physical ports, create virtual networks, and support Remote Ethernet Devices. Zones allow you to group interfaces and apply firewall rules to all member devices. Network redundancy and availability is provided by failover and load balancing. Other settings allow you to provide secure wireless broadband service to mobile devices and to configure advanced support for IPv6 device provisioning and traffic tunnelling.
