## Task 6: Create a custom route
In this task, you use a network virtual appliance (NVA) to help secure and monitor traffic. You want to ensure communication between front-end public servers and internal private servers is always routed through the appliance.
In this task, you want to control network traffic between the perimeter subnet and the internal core services subnet. A virtual network appliance will be installed in the core services subnet and all traffic should be routed there.
1. In the Azure portal, select **Route tables**, and then select **Create**. Provide the route table parameters.
1. Search for select the `CoreServicesVnet`.
1. Select **Subnets** and then **+ Create**. Be sure to **Save** your changes.

1. After the route table deploys, select **Go to resource**.
1. Select **Routes** and then **+ Add**. Create a route from the future NVA to the CoreServices virtual network.

1. Select **+ Add** when the route is completed. The last thing to do is associate the route with the subnet.
