What are the different types of VPN in Azure?

VPNs in Azure come in different shapes and sizes, each with its own distinct set of features. The most common type of VPN is the Site-to-Site VPN, which connects two on-premises sites together using a secure IPsec tunnel. Site-to-Site VPNs are ideal for organizations with remote locations that need to be connected to the main office. Another popular type of VPN is the Point-to-Site VPN, which establishes a connection from an individual computer to an Azure VNet. Point-to-Site VPNs are perfect for telecommuters and other users who need access to resources in a private VNet. Lastly, there’s the ExpressRoute circuit, which provides a direct connection between an on-premises site and Microsoft Azure (or other cloud providers) without going through the public internet. ExpressRoute circuits are typically used by large organizations with high bandwidth needs.

When it comes to VPNs, there are two types of tunneling that are commonly used: point-to-point tunneling protocol (PPTP) and layer 2 tunneling protocol (L2TP). Let’s take a closer look at each one.

Point-to-Point Tunneling Protocol (PPTP)

PPTP is a popular type of VPN tunneling because it’s been around for a long time and is built into many Operating Systems (like Windows). It’s also relatively easy to set up. PPTP uses a Point-to-Point Protocol (PPP) and relies on the GRE protocal. Essentially, data is encapsulated and then sent over the internet to the VPN server where it is decapsulated and routed to the intended destination. One downside of PPTP is that it’s not as secure as some other tunneling protocols because it doesn’t use encryption.

Layer 2 Tunneling Protocol (L2TP)

L2TP is another common type of VPN tunneling that offers better security than PPTP because it uses both an L2F protocol and IPSec for encryption. Data is first encapsulated with L2F before being encrypted with IPSec, making it more difficult for someone to eavesdrop on your connection. L2TP is often used in conjunction with other protocols like PPTP or SSTP for added security.

When creating a VPN in AWS, two different types of gateways are required: an internet gateway and a virtual private gateway.

An internet gateway is used to allow communication between the VPC and the Internet. This is the most common type of gateway and is used for general web browsing, downloading files, etc. A virtual private gateway is used to allow communication between the VPC and a remote network, such as a company’s on-premises network. This type of gateway is typically used for more sensitive data transfers, such as accessing customer data or transferring financial information.

There are three main types of VPN: remote access, personal, and mobile.

A remote access VPN allows users to connect to a network from a remote location. This type of VPN is often used by employees who need to access their company network from home or while traveling.

A personal VPN service encrypts a user’s internet traffic and routes it through a server in another location. This type of VPN is often used by people who want to protect their privacy online, or by businesses that need to secure their data.

A mobile VPN allows users to connect to a network from a mobile device. This type of VPN is often used by people who need to access their company network while they are on the go.

There are four main types of VPN: remote access, intranet-based site-to-site, extranet-based site-to-site, and possibility for Internet users to connect directly to the resources of a specific corporation or individual.

A remote access VPN is used by individuals who want to connect to a private network from a remote location. This type of VPN requires that the user have a broadband connection and that special client software be installed on the user’s computer. Once the user has connected to the private network, he or she will be able to access any of the resources on that network as if he or she were physically present in the office.

An intranet-based site-to-site VPN connects two parts of a company’s internal network that are not normally connected. For example, an organization with multiple locations may use an intranet-based VPN to connect its corporate headquarters with its branch offices. Each office would have its own local network, but they would all be able to share files and other resources as if they were on the same physical network.

An extranet-based site-to-site VPN connects two networks belonging to different organizations. For example, a company may create an extranet for its suppliers so that they can securely exchange information such as purchase orders and invoices. Alternatively, an extranet could be set up between a company and its customers, so that both parties can securely exchange information such as order status updates and shipping schedules.

Finally, there is also the possibility for Internet users to connect directly to the resources of a specific corporation or individual without going through their ISP first. This type of connection is known as a direct tunneling connection, and it requires special client software in order to work properly.
