Creating a new route table and a default route for the private network

The purpose of creating one is for protected hosts to take a default route to the private interface of the SNS firewall.

Creating the private route table

In the COCKPIT 3DS OUTSCALE console, under the Network/Security menu:

1. Select Route tables.
2. Click on Create.
3. Name your route table (e.g., Documentation-Private-Route-Table ).
4. Select the associated VPC (VPC Documentation in the example).
5. Confirm by clicking on Create.

Creating the route in the private route table of the VPC

1. Select the private route table created earlier (Documentation-Private-Route-Table in the example).
   Details about the route table will appear in the lower section of the configuration window.
   
2. In the details of the route table, click on Create Route.
3. In the Target field, select the private interface of your SNS EVA instance (Documentation-Private-Interface in the example).
4. Click on All IPs.
   The value 0.0.0.0/0 will automatically be entered in the Destination field.
5. Confirm by clicking on Create.

Associating this route table with the private sub-network of the VPC

1. Select the private route table created earlier (Documentation-Private-Route-Table in the example).
2. Click on Attach.
3. Select the private subnetwork of the VPC (Documentation-VPC-Private in the example).
4. Click on Attach to confirm the configuration.
   The Explicit associations column reflects this new status (switched from 0 to 1).
