The iShield requires an Internet connection and routing to be able to send and receive internet traffic for your network.
Select the Connections & Routing from the Menu.
The connection and routing section allows you to configure the iShield to be able to connect to the Internet, you can have multiple connections, best practice would be to have 2 connections. One primary connection and one as a failover connection in the event of our primary connection failing.
In the event of the primary going down the failover connection will automatically switch over and when the primary connection has been restored it will automatically switch back.
