Create Your Own Authenticated Gateway And Command Your Network

This article helps you configure the necessary VPN Gateway point-to-site (P2S) server settings to let you securely connect individual clients running Windows, Linux, or macOS to an Azure VNet. P2S VPN connections are useful when you want to connect to your VNet from a remote location, such as when you're telecommuting from home or a conference. You can also use P2S instead of a site-to-site (S2S) VPN when you have only a few clients that need to connect to a virtual network (VNet). P2S connections don't require a VPN device or a public-facing IP address.

Create Your Own Authenticated Gateway And Command Your Network

When using a virtual network as part of a cross-premises architecture, be sure to coordinate with your on-premises network administrator to carve out an IP address range that you can use specifically for this virtual network. If a duplicate address range exists on both sides of the VPN connection, traffic will route in an unexpected way. Additionally, if you want to connect this virtual network to another virtual network, the address space cannot overlap with the other virtual network. Plan your network configuration accordingly.

The virtual network gateway uses specific subnet called the gateway subnet. The gateway subnet is part of the virtual network IP address range that you specify when configuring your virtual network. It contains the IP addresses that the virtual network gateway resources and services use.

If you see an error that specifies that the address space overlaps with a subnet, or that the subnet isn't contained within the address space for your virtual network, check your VNet address range. You may not have enough IP addresses available in the address range you created for your virtual network. For example, if your default subnet encompasses the entire address range, there are no IP addresses left to create additional subnets. You can either adjust your subnets within the existing address space to free up IP addresses, or specify an additional address range and create the gateway subnet there.

Specify in the values for Public IP address. These settings specify the public IP address object that gets associated to the VPN gateway. The public IP address is assigned to this object when the VPN gateway is created. The only time the Public IP address changes is when the gateway is deleted and re-created. It doesn't change across resizing, resetting, or other internal maintenance/upgrades of your VPN gateway.

You can see the deployment status on the Overview page for your gateway. After the gateway is created, you can view the IP address that has been assigned to it by looking at the VNet in the portal. The gateway appears as a connected device.

When working with gateway subnets, avoid associating a network security group (NSG) to the gateway subnet. Associating a network security group to this subnet may cause your virtual network gateway (VPN and Express Route gateways) to stop functioning as expected. For more information about network security groups, see What is a network security group?.

Self-signed root certificate: If you aren't using an enterprise certificate solution, create a self-signed root certificate. Otherwise, the certificates you create won't be compatible with your P2S connections and clients will receive a connection error when they try to connect. You can use Azure PowerShell, MakeCert, or OpenSSL. The steps in the following articles describe how to generate a compatible self-signed root certificate:

Self-signed root certificate: Follow the steps in one of the following P2S certificate articles so that the client certificates you create will be compatible with your P2S connections.

If you don't see tunnel type or authentication type on the Point-to-site configuration page, your gateway is using the Basic SKU. The Basic SKU doesn't support IKEv2 or RADIUS authentication. If you want to use these settings, you need to delete and recreate the gateway using a different gateway SKU.

Navigate to your Virtual network gateway -> Point-to-site configuration page in the Root certificate section. This section is only visible if you have selected Azure certificate for the authentication type.

Each VPN client is configured using the files in a VPN client profile configuration package that you generate and download. The configuration package contains settings that are specific to the VPN gateway that you created. If you make changes to the gateway, such as changing a tunnel type, certificate, or authentication type, you'll need to generate another VPN client profile configuration package and install it on each client. Otherwise, your VPN clients may not be able to connect.

Use 'ipconfig' to check the IPv4 address assigned to the Ethernet adapter on the computer from which you're connecting. If the IP address is within the address range of the VNet that you're connecting to, or within the address range of your VPNClientAddressPool, this is referred to as an overlapping address space. When your address space overlaps in this way, the network traffic doesn't reach Azure, it stays on the local network.

Once your connection is complete, you can add virtual machines to your VNets. For more information, see Virtual Machines. To understand more about networking and virtual machines, see Azure and Linux VM network overview.

2. Test the domain name for a 200 OK response using either of the commands mentioned previously in the Test your API section. If you get a 500 server error code, then the distribution might not be deployed. If you get no response, the CloudFront DNS record has not yet propagated. In either case, confirm that 15-20 minutes have elapsed since you created your distribution. Then, retry the procedure.

Important: If you turned on AWS Identity and Access Management (IAM) authentication on a method for a particular API resource, then you must append the resource name to the end of the distribution domain name when invoking your API. The full invoke URL (including the resource name) looks similar to one of the following examples. The output depends on whether you entered an Origin Path when you created the distribution:

2. On the Create Distribution page, for Cache and origin request settings, choose Use a cache policy and origin request policy. Then, under Cache Policy, choose either an existing cache policy or create a new cache policy that adds the Authorization header to your CloudFront allow list.

4. On the Create Distribution page, for Cache and origin request settings, choose Use a cache policy and origin request policy. Then, under Cache Policy, choose either an existing cache policy or create a new cache policy that adds the Authorization and Host header to your CloudFront allow list.

Users first authenticate to Duo Network Gateway and approve a two-factor authentication request before they may access your different protected services. Session awareness minimizes repeated MFA prompts as users access additional services and hosts via your gateway.

Duo Network Gateway gives you granular access control per web application, set of SSH servers, and user groups. You can specify different policies to make sure only trusted users and endpoints are able to access your internal services. For example, you can require that SSH users complete two-factor authentication at every login, but once every seven days when accessing a web application. Duo checks the user, device, and network against an application's policy before allowing access to the application.

The following command instructs Docker Compose to download the Duo Network Gateway images and start containers using them. Specify the YML file downloaded in the last step in the command. Note that your YML file name may reflect a different version than the example command shown. Replace the file name in the example with your downloaded YML file's actual name.

The following command instructs Docker Compose to download the Duo Network Gateway images (including the additional DNS container for application host access like RDP or SMB) and start containers using them. Specify the YML files downloaded in the last step in the command. Note that your YML file names may reflect a different version than the example command shown. Replace the file names in the example with your downloaded YML file's actual names.

In a browser navigate to https://:8443 from an internal network to log into the Duo Network Gateway admin console. Your browser will warn you about an untrusted certificate the first time you access the page. Dismiss the warning and continue onto the page. If you would like to verify the certificate displayed by your browser is the same one loaded by the Duo Network Gateway please see this knowledge base article.

Duo Network Gateway allows you to remotely access your SSH servers by tunneling the connection through it using HTTPS. You can group access to a set of servers, after you've authenticated you'll be able to connect all servers in that group. You might decide to group servers by level of security or by departments within your organization. Each group of servers can have its own policies in the Duo Admin Panel.

You can group access to a set of servers in one application relay; after you've authenticated you'll be able to connect all servers in that group. You might decide to group servers by level of security or by departments within your organization. Each group of application servers can have its own policies in the Duo Admin Panel.

Due to the absence of a "proxy" configuration, we rely on subdomain delegation to the Duo Network Gateway. You configure the Duo Network Gateway with an external/internal pair of subdomains, where the external subdomain is delegated by your main domain to the Duo Network Gateway, and the internal subdomain is one that is resolvable within the corporate network.
