Step 5: Connecting environments

AIX support in Skytap walk-through

To complete this section, you must first finish Step 4: Creating and using a template.

By default, environment networks are isolated from each other. But you can configure your networks so that VMs in one environment can communicate with VMs in another environment, or VMs in multiple environments can communicate with shared services in dedicated environments.

To enable communication between environments, use ICNR Inter-Configuration Network Routing – Connects networks from different environments to a single, shared server. Without ICNR, environments are on isolated networks. To learn more, see Networking between environments. . To enable ICNR, you must make a few small changes to the networks for both environments, including enabling NAT Network Address Translation – A networking feature that helps you connect environments that have overlapping network subnets. NAT prevents IP address conflicts by mapping an additional, unique IP address to every VM on a connected network. This NAT IP address is used for inbound and outbound communication with the connected network. To learn more, see Using Network Address Translation (NAT) to avoid IP address conflicts. .

For more details about ICNR, see Networking between environments.

Setting up the networks

By default, a network in an environment isn’t visible to networks outside of the environment. In these steps, you’ll change the settings for the environment networks so that they can communicate with each other.

Edit network settings for AIX-Beta-2

First we’ll change the network of AIX Beta-2 to make it visible to other networks.

Because both environments AIX-Beta-1 and AIX-Beta-2 are exact clones, including the IP addresses for each VM, we’ll also enable NAT to prevent IP address conflicts.

To change the network settings for AIX-Beta-2

  1. Click Networking: Settings.

    Networking: Settings

    The Network Settings page for AIX-Beta-2 displays.

  2. Click Edit Network

    Edit Network

    The Edit network dialog displays.

  3. Enable Visible to other networks and Apply NAT for connecting.

    Don’t change the NAT Subnet.

  4. Click Save Changes.

Edit network settings for AIX-Beta-1

Next we’ll change the network for AIX-Beta-1 to enable NAT and a unique subnet for NAT IP addresses.

To change the network settings for AIX-Beta-1
  1. In the navigation bar, click Environments. The Manage Environments and VMs page displays.

  2. Click AIX-Beta-1.

    environment startup

    The Environment Details page for AIX-Beta-1 displays.

  3. Click Networking: Settings.

    network settings

    The Network Settings page for AIX-Beta-1 displays.

  4. Click Edit Network

    network settings

    The Edit network dialog for AIX-Beta-1 displays.

  5. Enable Apply NAT for connecting and change the NAT Subnet to 10.0.8.0/22.

    edit network

  6. Click Save Changes.

Completing the connection between environments

Now that both environments are configured to enable ICNR, and while you’re still in environment AIX-Beta-1, the next step is to connect the environments together.

To connect the environments

  1. Click Connect to a network.

    network settings

    The Connect Network 1 to Another Network dialog displays.

  2. Next to AIX-Beta-2, click Connect to Network.
