Before configuring, you need to plan the deployment mode of Cyberoam. Cyberoam can be placed in
Bridge or Gateway/Route mode according to your requirement.
To control the Internet access through Cyberoam the entire Internet bound traffic from the LAN network
should pass through Cyberoam.

PLANNING THE CONFIGURATION
Gateway Mode
Configure as Gateway if you want to use Cyberoam as

Apart from configuring Gateway IP address (IP address through which all the traffic will be routed),
you must also configure LAN and WAN IP addresses.
