Managing router interfaces

Prerequisites

• You have a virtual router created, as described in Creating virtual routers.

To add an external router interface

1. If you already have an external gateway, remove the existing one first.
2. On the Routers screen, click the router name to open the list of its interfaces.
3. Click Add on the toolbar, or click Add interface if there are no interfaces to show.

4. In the Add interface window, do the following:

   1. Select External gateway.
   2. From the Network drop-down menu, select a physical network to connect to the router. The new interface will pick an unused IP address from the selected physical network. You can also provide a specific IP address from the selected physical network to assign to the interface in the IP address field.
   3. [Optional] Select or deselect the SNAT check box to enable or disable SNAT on the external gateway of the router. With SNAT enabled, the router replaces VM private IP addresses with the public IP address of its external gateway.
