Creating and editing a Skytap on Azure ExpressRoute connection

A Skytap on Azure ExpressRoute connection is a dedicated, secure network tunnel between a Skytap environment and an Azure virtual network.

For example, you can use a Skytap on Azure ExpressRoute connection to connect a Skytap environment to your corporate intranet to give your virtual data center access to corporate resources (such as databases, source repositories, and builds).

Your customer account can have up to ten WANs connected at the same time. If you need additional WANs, contact your Skytap sales representative. A WAN is a VPN or Skytap on Azure ExpressRoute connection

Before you begin

Before you begin, you’ll need:

  • A valid and active Microsoft Azure subscription.
  • An Azure region enabled for your Skytap account.
  • An administrator account in Skytap.
  • A Skytap environment.

    Use Skytap Subnet from the environment to define the Skytap subnet for the Skytap on Azure ExpressRoute connection.

    subnet

  • An Azure virtual network.

    The Azure virtual network will define the remote subnet. Included remote subnets can’t overlap with restricted subnets or the Skytap subnet defined in the VPN settings. For more information, see Remote Subnets settings.

  • An unattached Skytap static public IP address.

    A static public IP address is used as the Skytap peer IP address for the Skytap on Azure ExpressRoute connection.

    For instructions, see Adding a static public IP address to your account.

    The static public IP address is dedicated to the Skytap on Azure ExpressRoute connection; it isn’t accessible via the public internet.

    If you don’t have an available public IP address, contact your Skytap account representative.

Creating and configuring a Skytap on Azure ExpressRoute connection

To create a Skytap on Azure ExpressRoute connection
  1. From the navigation bar, click Manage > WANs.

    WANS page

  2. Click New ExpressRoute. The New WAN page loads.

    New VPN

  3. Type a Name for the new Skytap on Azure ExpressRoute connection.
  4. Select the Azure Region where the ExpressRoute will be created.
  5. Choose the Connection type, either Skytap-managed circuit or Customer-managed circuit.
  6. If this is a Customer-managed circuit, type or paste the ExpressRoute circuit Service key.
  7. Choose a Skytap static public IP address as the Skytap peer IP.
  8. To assign NAT IP addresses to any VMs connected to the ExpressRoute, select Apply NAT for connecting networks. This setting allows you to connect Skytap environments with overlapping IP addresses to the Skytap on Azure ExpressRoute connection. For more information, see Apply NAT for connecting networks.
  9. Type the Skytap subnet – the subnet of the environment that will be connected.
  10. Click Save. The Details tab displays a summary of the Skytap on Azure ExpressRoute connection settings, along with the message, We’re waiting for the authorization key so we can finish building your connection.

    Provisioning usually takes only a few minutes but can sometimes take up to an hour.

  12. Sign into your Azure subscription and follow these steps to connect your ExpressRoute to your virtual network gateway.

    The Resource ID and Authorization Key are displayed on the Details tab of the Skytap WANs page.

    • For the Authorization key of the Connection object, use the Authorization Key.
    • For the Peer circuit URI of the Connection object, use the Resource ID.
  13. Type the Azure virtual network subnet into Remote Subnet. Optionally, you can add remote subnets to exclude. Included remote subnets can’t overlap with restricted subnets or the Skytap subnet defined in the Skytap on Azure ExpressRoute connection settings. For more information, see Remote Subnets settings.

    remote subnets

    1. Enter a subnet range in Remote Subnets.

      The supported remote subnets are within the 3 to 32 bits range.

      1. Select include or exclude.
      2. Click Add.
  14. Test the WAN.
