Azure S2S VPN connections provide secure, cross-premises connectivity between customer premises and Azure. This tutorial walks through IPsec S2S VPN connection life cycles such as creating and managing a S2S VPN connection. You learn how to:

• Create an S2S VPN connection
• Update the connection property: pre-shared key, BGP, IPsec/IKE policy
• Add more VPN connections
• Delete a VPN connection

The following diagram shows the topology for this tutorial:

Working with Azure Cloud Shell and Azure PowerShell

This article uses PowerShell cmdlets. To run the cmdlets, you can use Azure Cloud Shell. The Azure Cloud Shell is a free interactive shell that you can use to run the steps in this article. It has common Azure tools preinstalled and configured to use with your account.

To open the Cloud Shell, just select Try it from the upper right corner of a code block. You can also launch Cloud Shell in a separate browser tab by going to https://shell.azure.com/powershell. Select Copy to copy the blocks of code, paste it into the Cloud Shell, and press enter to run it.

Requirements

Complete the first tutorial: Create VPN gateway with Azure PowerShell to create the following resources:

1. Resource group (TestRG1), virtual network (VNet1), and the GatewaySubnet
2. VPN gateway (VNet1GW)

The virtual network parameter values are listed below. Note the additional values for the local network gateway which represent your on-premises network. Change the values below based on your environment and network setup, then copy and paste to set the variables for this tutorial. If your Cloud Shell session times out, or you need to use a different PowerShell window, copy and paste the variables to your new session and continue the tutorial.

Note

If you are using this to make a connection, be sure to change the values to match your on-premises network. Surrogate key generator in datastage with example. If you are just running these steps as a tutorial, you don't need to make changes, but the connection will not work.

The workflow to create an S2S VPN connection is straightforward:

1. Create a local network gateway to represent your on-premises network
2. Create a connection between your Azure VPN gateway and the local network gateway

Create a local network gateway

A local network gateway represents your on-premises network. You can specify the properties of your on-premises network in the local network gateway, including:

• Public IP address of your VPN device
• On-premises address space
• (Optional) BGP attributes (BGP peer IP address and AS number)

Create a local network gateway with the New-AzLocalNetworkGateway command.

Create a S2S VPN connection

Next, create a Site-to-Site VPN connection between your virtual network gateway and your VPN device with the New-AzVirtualNetworkGatewayConnection. Notice that the '-ConnectionType' for Site-to-Site VPN is IPsec.

Add the optional '-EnableBGP $True' property to enable BGP for the connection if you are using BGP. It is disabled by default. Parameter '-ConnectionProtocol' is optional with IKEv2 as default. You can create the connection with IKEv1 protocols by specifying -ConnectionProtocol IKEv1.

Update the VPN connection pre-shared key, BGP, and IPsec/IKE policy

View and update your pre-shared key

Azure S2S VPN connection uses a pre-shared key (secret) to authenticate between your on-premises VPN device and the Azure VPN gateway. You can view and update the pre-shared key for a connection with Get-AzVirtualNetworkGatewayConnectionSharedKey and Set-AzVirtualNetworkGatewayConnectionSharedKey.

Important

The pre-shared key is a string of printable ASCII characters no longer than 128 in length.

Linksys Pre Shared Key

This command shows the pre-shared key for the connection:

The output will be 'Azure@!b2C3' following the example above. Use the command below to change the pre-shared key value to 'Azure@!_b2=C3':

Enable BGP on VPN connection

Azure VPN gateway supports BGP dynamic routing protocol. You can enable BGP on each individual connection, depending on whether you are using BGP in your on-premises networks and devices. Specify the following BGP properties before enabling BGP on the connection:

• Azure VPN ASN (Autonomous System Number)
• On-premises local network gateway ASN
• On-premises local network gateway BGP peer IP address

If you have not configured the BGP properties, the following commands add these properties to your VPN gateway and local network gateway: Set-AzVirtualNetworkGateway and Set-AzLocalNetworkGateway.

Use the following example to configure BGP properties:

Enable BGP with Set-AzVirtualNetworkGatewayConnection.

You can disable BGP by changing the '-EnableBGP' property value to $False. Refer to BGP on Azure VPN gateways for more detailed explanations of BGP on Azure VPN gateways.

Apply a custom IPsec/IKE policy on the connection

You can apply an optional IPsec/IKE policy to specify the exact combination of IPsec/IKE cryptographic algorithms and key strengths on the connection, instead of using the default proposals. The following sample script creates a different IPsec/IKE policy with the following algorithms and parameters:

• IKEv2: AES256, SHA256, DHGroup14
• IPsec: AES128, SHA1, PFS14, SA Lifetime 14,400 seconds & 102,400,000 KB

Refer to IPsec/IKE policy for S2S or VNet-to-VNet connections for a complete list of algorithms and instructions.

Add another S2S VPN connection

Add an additional S2S VPN connection to the same VPN gateway, create another local network gateway, and create a new connection between the new local network gateway and the VPN gateway. Use the following examples, making sure to modify the variables to reflect your own network configuration.

There are now two S2S VPN connections to your Azure VPN gateway.

Delete a S2S VPN connection

Delete a S2S VPN connection with Remove-AzVirtualNetworkGatewayConnection.

Delete the local network gateway if you no longer need it. You cannot delete a local network gateway if there are other connections associated with it.

Clean up resources

If this configuration is part of a prototype, test, or proof-of-concept deployment, you can use the Remove-AzResourceGroup command to remove the resource group, the VPN gateway, and all related resources.

Next steps

Introduction

This document describes a sample configuration for Wireless Protected Access (WPA) and WPA2 with a pre-shared key (PSK).

Prerequisites

Requirements

Cisco Pre-shared-key

Cisco recommends that you have knowledge of these topics:

• Familiarity with the GUI or the command-line interface (CLI) for the Cisco IOS^® software
• Familiarity with the concepts of PSK, WPA, and WPA2

Components Used

The information in this document is based on Cisco Aironet 1260 Access Point (AP) that runs Cisco IOS Software Release 15.2JB.

The information in this document was created from the devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If your network is live, make sure that you understand the potential impact of any command.

Configure

Configuration with GUI

This procedure describes how to configure WPA and WPA2 with a PSK in the Cisco IOS software GUI:

1. Set up the Encryption Manager for the VLAN defined for the Service Set Identifier (SSID). Navigate to Security > Encryption Manager, ensure Cipher is enabled, and select AES CCMP + TKIP as the cipher to be used for both SSIDs.
   
2. Enable the correct VLAN with the encryption parameters defined in Step 1. Navigate to Security > SSID Manager, and select the SSID from the Current SSID List. This step is common for both WPA and WPA2 configuration.
   
3. In the SSID page, set Key Management to Mandatory, and check the Enable WPA checkbox. Select WPA from the drop-down list in order to enable WPA. Enter the WPA Pre-shared Key.
   
4. Select WPA2 from the drop-down list in order to enable WPA2.
