Windows Azure VPN Setup Tutorial for Beginners

Setting up a Windows Azure VPN is a crucial step in securing your network, and it's easier than you think. Windows Azure VPN allows you to create a secure connection between your on-premises network and the Azure cloud.

To begin, you'll need to create a virtual network in the Azure portal. This is where you'll configure your VPN settings and create a secure connection between your networks.

You can create a virtual network by selecting the "Create a resource" button in the Azure portal, then choosing "Virtual network" from the drop-down menu. This is where you'll start building your VPN setup.

A virtual network gateway is a critical component of your VPN setup, as it enables secure communication between your on-premises network and Azure. You'll need to create a virtual network gateway as part of your VPN setup.

To set up a Windows Azure VPN, you'll need to start with a few prerequisites. You'll need an Azure account with an active subscription. This can be created for free if you don't already have one.

It's also essential to have the IP address ranges from your on-premises network configuration. If you're not familiar with these details, you'll need to coordinate with someone who can provide them for you. This information is crucial for creating the configuration in Azure.

VPN devices are also a key part of the setup process.

Here are the specific requirements you'll need to keep in mind:

To set up a VPN on Windows Azure, you need to create a site-to-site VPN connection between your virtual network gateway and your on-premises VPN device. This requires a VPN device and a shared key, which should be the same on both sides of the connection.

You'll also need to configure your VPN device with the public IP addresses of your virtual network gateway instances, which can be obtained from the Azure portal. If you're using an active-active mode gateway, make sure to configure both IP addresses, one for each active gateway VM instance.

To create a site-to-site VPN connection, you can use the Azure portal to create a connection with the following values: local network gateway name, connection name, and shared key. You can also use PowerShell to create the connection.

Here's a summary of the steps to create a site-to-site VPN connection:

Note that you should use a more complex shared key, as recommended by Azure.

To view your public IP address, go to your virtual network gateway Properties page, not the Overview page. You might need to expand Settings to see the Properties page in the list.

If your gateway is in active-passive mode, you'll only see one IP address. But if it's in active-active mode, you'll see two public IP addresses listed, one for each gateway VM instance. This is important to keep in mind when creating a site-to-site connection.

To view more information about the IP address object, click the associated IP address link.

It's worth noting that in active-active mode, you must specify each IP address when configuring your VPN device because both gateway VMs are active. This ensures a secure and reliable connection.

To create a local network gateway, you need to specify the name and resource group. The name should be Site1 and the resource group should be TestRG1, located in East US.

You can create a local network gateway by using the portal, going to Local network gateways and opening the Create local network gateway page. On the Basics tab, specify the values for your local network gateway.

The VPN Gateway only supports one IPv4 address for each FQDN, so make sure your domain name resolves to a single IP address. This will eliminate any uncertainty and ensure your connection works smoothly.

To configure your local network gateway, follow these steps:

The VPN Gateway maintains a DNS cache that's refreshed every 5 minutes, and it tries to resolve the FQDNs for disconnected tunnels only. Resetting the gateway also triggers FQDN resolution.

Configure your VPN device with the shared key, public IP addresses of your virtual network gateway instances, and ensure tunnels are established to each gateway VM instance for active-active mode VPN gateways.

You'll need the shared key, which is the same one you specified when creating your site-to-site VPN connection. Use a simple shared key for now, but consider generating a more complex key for better security.

To obtain the public IP addresses, get the IP address for each VM instance, and if your gateway is in active-active mode, you'll have an IP address for each active gateway VM instance.

For active-standby mode gateways, you'll only have one IP address, so make sure to configure your device with both IP addresses if you have an active-active mode gateway.

If your VPN device doesn't support establishing tunnels to each gateway VM instance, consider configuring your gateway for active-standby mode instead.

You might be able to download a VPN device configuration script, but be sure to check for compatible VPN devices and known device compatibility issues before configuring your device.

Here are the steps to follow:

Resetting a gateway can be a lifesaver if you're experiencing cross-premises VPN connectivity issues. This can happen if your on-premises VPN devices are working correctly but can't establish IPsec tunnels with the Azure VPN gateways.

In this situation, you can reset the active-active gateway using the portal. To do this, go to the virtual network gateway you want to reset and navigate to the Help section.

You'll see a Reset option - select this and confirm your action. The current active instance of the Azure VPN gateway will be rebooted immediately, causing a gap in VPN connectivity.

Resetting the gateway can limit future root cause analysis of the issue, so be sure to troubleshoot thoroughly before taking this step.

To create a VPN connection between your virtual network gateway and on-premises VPN device, you need to create a site-to-site VPN connection. This requires a shared key, which is the same one you specify when creating your site-to-site VPN connection.

For active-active mode gateways, ensure tunnels are established to each gateway VM instance. If you establish a tunnel to only one gateway VM instance, the connection will go down during maintenance. If your VPN device doesn't support this setup, configure your gateway for active-standby mode instead.

To create a connection, use the following values: local network gateway name, connection name, and shared key. For example, you can use a local network gateway name of "Site1" and a connection name of "VNet1toSite1".

Here's a step-by-step guide to creating a VPN connection:

1. Go to the virtual network gateway and open it.

2. Select Connections at the top of the page.

3. Click + Add to open the Create connection page.

4. On the Basics tab, configure the values for your connection.

5. Select the Settings tab and configure the following values:

* NAT Rules Associations: leave both Ingress and Egress as 0 selected.

6. Select Review + create to validate your connection settings.

7. Select Create to create the connection.

Note that you can have multiple connections with a single gateway, but the address spaces cannot overlap between any of the connections.

To configure Point-to-Site configuration, navigate to your Virtual network gateway resource and click "Point-to-site configuration". The address pool refers to the range of private IP addresses assigned to client computers connecting to the VPN.

Select a subnet that doesn't conflict with the existing subnets in your private network. Assuming you've created a VNet without modifying the default subnet configuration, your VNet likely falls within the 10.x.x.x range. You can safely use the address pool 172.16.254.0/24 by simply copying it.

Choose OpenVPN (SSL) as the tunnel type. This is because OpenVPN is supported on multiple client operating systems, including Windows, macOS, and Linux.

Select Azure Active Directory as the authentication type. This is a secure and reliable option that uses Azure's identity management system to authenticate users.

You'll also need to specify your Tenant, which can be found by following the link to Microsoft's documentation. Make sure to copy the correct Tenant ID.

After populating all the variables, click "Save". This process will take around 15 minutes to complete.

Once the configuration is saved, you can download the VPN client from your Virtual network gateway resource.
