In vCloud Air, the gateway supports configuring static routing between the interfaces in the gateway. By default, static routing is disabled for a gateway. (On an internal network, which does not connect to a gateway, static routing is not applicable).

On a gateway network, network traffic goes to the gateway's default interface, which connects to the Internet. When you configure a static route between interfaces, traffic bypasses the default interface to the Internet.

You might want to enable static routing on a gateway for the following use cases:

So that all the traffic from the external network traverses the antivirus appliance first before accessing your virtual machines

When you want a Web server on one gateway network to connect to an application server on another gateway network without having the traffic traverse the Internet

Configure static routing for a gateway network by navigating from vCloud Air to the networking services for the gateway in vCloud Director:

vCloud Air Dashboard > Gateway tab > click the gateway > Manage Advanced Gateway Settings > vCloud Director Administration page > Edge Gateways tab > select the gateway, right-click and choose Edge Gateway Services > Static Routing tab

For the steps to configure static routing by using vCloud Director, see the following topics in vCloud Director Administrator's Guide:
