# Tutorial: Create and manage a VPN gateway using Azure portal
# Configure active-active VPN gateways using the portal

This article helps you create highly available active-active cross-premises and VNet-to-VNet connections using the Resource Manager deployment model and Azure portal. You can also configure an active-active gateway using PowerShell.

## About highly available cross-premises connections
This article helps you create highly available active-active VPN gateways using the Resource Manager deployment model and Azure portal. You can also configure an active-active gateway using [PowerShell](vpn-gateway-activeactive-rm-powershell.md).

To achieve high availability for cross-premises and VNet-to-VNet connectivity, you should deploy multiple VPN gateways and establish multiple parallel connections between your networks and Azure. See [Highly Available cross-premises and VNet-to-VNet connectivity](vpn-gateway-highlyavailable.md) for an overview of connectivity options and topology.

If you already have a VPN gateway, you can [Update an existing VPN gateway from active-standby to active-active, or vice versa](#active).

> [!IMPORTANT]
> The active-active mode is available for all SKUs except Basic.
> The active-active mode is available for all SKUs except Basic or Standard.

## Prerequisites
The steps in this article help you configure a VPN gateway in active-active mode. There are a few differences between active-active and active-standby modes. The other properties are the same as the non-active-active gateways.

* Active-active gateways have two Gateway IP configurations and two public IP addresses.
* Active-active gateways have active-active setting enabled.
* The virtual network gateway SKU can't be Basic or Standard.

An Azure account with an active subscription. If you don't have one, [create one for free](https://azure.microsoft.com/free/?ref=microsoft.com&utm_source=microsoft.com&utm_medium=docs&utm_campaign=visualstudio).
If you already have a VPN gateway, you can [Update an existing VPN gateway](#update) from active-standby to active-active mode, or from active-active to active-standby mode.

This section helps you change an existing Azure VPN gateway from active-standby to active-active mode, and from active-active to active-standby mode. When you change an active-standby gateway to active-active, you create another public IP address, then add a second gateway IP configuration.

### Change active-standby to active-active

## Next steps
Use the following steps to convert active-standby mode gateway to active-active mode. If your gateway was created using the Resource Manager deployment model, you can also upgrade the SKU on this page.

1. Navigate to the page for your virtual network gateway.

1. On the left menu, select **Configuration**.

1. On the **Configuration** page, configure the following settings:

* Change the Active-active mode to **Enabled**.
* Click **Create another gateway IP configuration**.

:::image type="content" source="./media/active-active-portal/configuration.png" alt-text="Screenshot shows the Configuration page.":::

1. On the **Choose public IP address** page and either specify an existing public IP address that meets the criteria, or select **+Create new** to create a new public IP address to use for the second VPN gateway instance.

Once you have a VPN gateway, you can configure connections. The articles below will help you create a few of the most common configurations:
1. On the **Create public IP address** page, select the **Basic** SKU, then click **OK**.

1. At the top of the **Configuration** page, click **Save**. This update can take about 30-45 minutes to complete.

### Change active-active to active-standby

Use the following steps to convert active-active mode gateway to active-standby mode.

1. Navigate to the page for your virtual network gateway.

1. On the left menu, select **Configuration**.

1. On the **Configuration** page, change the Active-active mode to **Enabled**.

1. At the top of the **Configuration** page, click **Save**.
