Creating the External Network

You must have at least one external network before you can create your grids.

To create the external network

1. Select Administration from the left Menu.

   The Administration page appears.

2. Click the Networks tab.
3. Click the External tab.
4. Click the Add button.

   The Add an External Network Dialog appears.

5. Specify the following information:

   Network IP

   Network address of the subnet and this address is not used for assigning to any other nodes. For example, 155.35.86.0.

   CIDR

   The length of the “subnet” bits in the netmask. There is a 1-1 correlation between CIDR prefix length and the traditional IP netmask. For example, 24.

   Gateway IP

   Gateway network address of the external network. Gateway IP is required only for networks that allow access beyond the subnet, but you may have it defined on “private” networks too if desired. For example, 155.35.86.1.

6. Click the Save button.

   The Configure New Network dialog appears.

7. Click the Add button and specify the following fields with the correct set of IPs.

   IP Range

   IP range for the grid.

   The Start, Stop, and Scope fields auto-populate based on the network you select. You can change these fields as needed.

   Start

   First IP in the IP range for the grid.

   End

   Last IP in the IP range for the grid.

   Scope

   Indicates if the range is hardware or application related for external networks.

   Hardware: Indicates that the IP range will only be used for grid servers.

   Applications: Indicates that the IP range will only be used for application IPs in your grids.

8. Click the Save button on the Add/Edit IP Range dialog.

   Note: The hardware and application IP do not have to be on the same network. If you want to configure a different network for each, repeat steps 4 through 8 above.

9. Click the Save button on the Edit an External Network dialog.
