What Is A Site To Site Vpn – This article helps you understand how Azure Point-to-Site VPN routing works. The behavior of P2S VPN routing depends on the client’s OS, the protocol used for the VPN connection, and how virtual networks (VNets) are connected to each other. For more information about Point-to-Site VPN, including supported protocols, see About Point-to-Site VPN.

If you make a change to your network topology and you have Windows VPN clients, the VPN client package for Windows clients must be downloaded and reinstalled for the changes to apply to the client.

The point-to-site VPN gateway connection in this example is for a VNet that is not connected or connected to any other virtual network (VNet1). In this example, clients can access VNet1.

In this example, the VPN gateway connection is point-to-site to VNet1. VNet1 is peer to VNet2. VNet 2 is peer-to-peer with VNet3. VNet1 is peer to VNet4. There is no direct peering between VNet1 and VNet3. VNet1 has “Allow gateway pass-through” and VNet2 and VNet4 have “Use remote gateways” enabled.

Clients running Windows can access peered VNets directly, but the VPN client must be downloaded again if any changes are made to VNet peering or network topology. Non-Windows clients can access the peered VNet directly. Access is not transitive and is limited to direct peering VNet only.

In this example, the VPN gateway connection is point-to-site to VNet1. VNet1 is connected to VNet2 using a Site-to-Site VPN connection. VNet2 is connected to VNet3 using a Site-to-Site VPN connection. There is no direct peering or Site-to-Site VPN connection between VNet1 and VNet3. Not all Site-to-Site connections use BGP for routing.

Clients using Windows or other supported operating systems can only access VNet1. To access additional VNets, BGP must be used.

In this example, the VPN gateway connection is point-to-site to VNet1. VNet1 is connected to VNet2 using a Site-to-Site VPN connection. VNet2 is connected to VNet3 using a Site-to-Site VPN connection. There is no direct peering or Site-to-Site VPN connection between VNet1 and VNet3. All Site-to-Site connections use BGP for routing.

Clients running Windows or another supported operating system can access any VNet connected with a Site-to-Site VPN connection, but routes to the connected VNets must be manually added to Windows clients.

In this example, the VPN gateway connection is point-to-site to VNet1. VNet1 is not connected/peered to any other virtual network, but is connected to the local site via a Site-to-Site VPN connection that does not run BGP.

In this example, the VPN gateway connection is point-to-site to VNet1. VNet1 is not connected to or attached to any other virtual network, but is connected to the local site (Site1) via a Site-to-Site VPN connection running BGP.

Windows clients can access the VNet and the branch office (Site1), but routes to Site1 must be manually added to the client. Non-Windows clients can access the VNet as well as a local branch office.

In this example, the VPN gateway connection is point-to-site to VNet1. VNet1 is connected to VNet2 using a Site-to-Site VPN connection. VNet2 is connected to VNet3 using a Site-to-Site VPN connection. There is no direct peering or Site-to-Site VPN tunnel between the VNet1 and VNet3 networks. VNet3 is connected to the branch office (Site1) using a Site-to-Site VPN connection. Not all VPN connections use BGP.

Clients using Windows can access the VNet and sites connected with a Site-to-Site VPN connection, but the routes to VNet2, VNet3, and Site1 must be manually added to the client. Non-Windows clients can access VNets and sites connected with a Site-to-Site VPN connection without any manual intervention. Access is transient and clients can access resources in any connected VNet and locations (on-premises). A virtual private network (VPN) allows users to securely connect to another network over the Internet by encrypting the connection from their device. A VPN makes your internet connection more secure and offers privacy and anonymity online.

Organizations, governments, and businesses of all sizes use VPNs to secure remote Internet connections to protect against data eavesdropping. Individuals also use personal VPNs to keep their locations private, securely encrypt data, and surf the web anonymously.

A business VPN is exactly what it sounds like: a VPN connection used by businesses and other professional organizations to securely connect their remote workforce and branches to the applications, data, tools and resources they need to do their jobs.

Many organizations use traditional perimeter security models to secure their corporate networks. Corporate VPNs reinforce security practices to provide remote workers and office workers with a virtual network through which they can access the corporate network via a public or private Internet connection anywhere in the world.

With a perimeter security model, a company’s IT team builds corporate security networks only within the organization’s physical structures and locations, aligning the security footprint of the computer network with that of the company’s premises. This alignment between physical structures and the computer network has historically enabled network security professionals to simplify visibility and management of network access.

Employees working at the organization’s headquarters connect directly to the corporate network at the corporate perimeter, eliminating the need to connect through a corporate VPN. However, branch employees, remote workers, or staff traveling outside the protected corporate perimeter need a corporate VPN for secure network connectivity while working from anywhere.

Organizations have historically relied on two types of corporate VPN connections to protect their employees outside of headquarters: a remote access VPN for remote workers and a site-to-site VPN for office workers.

A remote access VPN is a temporary connection between the user and the main office that is typically used to access data center applications. This connection may use IPsec, but it is also common to use SSL VPN to establish the connection between the user’s endpoint and the VPN gateway.

A site-to-site VPN is a persistent connection designed to act as an encrypted connection between offices (ie, “sites”). This is usually set up as an IPsec network connection between network equipment.

A remote access VPN provides remote users with secure access to the organization’s network infrastructure. It also encrypts all traffic that remote workers send to and receive from the network infrastructure, enabling an organization’s remote workers to securely access and use applications, data, tools and resources located in the company’s data center and headquarters.

A remote access VPN provides secure access by creating a tunnel between the organization’s network and the remote user that is “almost private”, even when the user is connecting to the network through a public Internet connection. Despite the public connection, the network connection is private because the network traffic is encrypted, making it unintelligible to any eavesdropper. Remote access encryption capabilities minimize the organization’s concern about tampering or data interception when data travels outside the corporate network between the secure perimeter and remote employees.

However, remote access VPN has its limitations. With the rapid growth of the remote workforce and cloud-based applications, organizations are finding that a remote access VPN is neither cloud-optimized nor secure.

Point To Site Remote Vpn Access

A remote access VPN is typically used in a hub-and-spoke architecture, where users sit on connections of varying length depending on their distance from the hub – the internal data center. Distance degrades performance and leads to latency issues, but this is still the optimal architecture for data center applications because the goal is to get to the hub. To compensate for external VPN network problems, organizations typically make compromises that have negative security implications.

Organizations with a remote workforce need the right network security architecture and solutions to optimize access to the data center, Internet and applications in public, private and hybrid clouds.

Unlike a remote access VPN, which connects individual devices or users to an organization’s corporate network, a site-to-site VPN is a connection between two or more networks, such as a corporate network and a branch office network. Many organizations choose site-to-site VPN so that they can use an Internet connection for private traffic instead of private Multiprotocol Label Switching (MPLS) circuits.

Site-to-site VPN is often used by companies with multiple offices in different geographic locations that need constant access and use of the company’s network. With a site-to-site VPN, a company can securely connect its corporate network to its remote offices to communicate and share resources with them as a single network.
