The following steps guide you through the setup of network gateways in a single-homed environment, where only the internal interface is enabled. This configuration is less common than one that is dual-homed.
To configure a network gateway in a single-homed environment
In the AMC, navigate to System Configuration > Network Settings.
In the Routing section, click Edit.
The Routing page displays.
To route traffic to your network gateway, select one of these routing modes:
Default gateway—Specify an IP address for the default gateway. Network traffic received by the appliance, but not matching a static route will be sent to this address.
No gateway—Network traffic received by the appliance, but not matching a static route is discarded.
Click Save.
