What is the difference between Azure Express Route and VPN gateway?

Summary

In this article, I will be discussing the difference between Azure ExpressRoute and VPN gateway, as well as answering common questions about VPN gateways in Azure.

Main Thought

Azure ExpressRoute and VPN gateway are both options for connecting your on-premises networks to Azure. However, they have different capabilities and use cases.

Key Points

1. ExpressRoute vs VPN gateway

ExpressRoute is a dedicated private connection that provides more reliable and consistent network performance compared to VPN gateways, which use the public internet. It is suitable for organizations with high bandwidth requirements and need a secure and direct connection to Azure.

2. Differences in functionality

ExpressRoute does not require a VPN gateway, as it operates on a dedicated private connection. VPN gateways, on the other hand, use VPN protocols to encrypt and secure network traffic over the public internet.

3. Coexistence of VPN and ExpressRoute in the same virtual network

It is possible to have both VPN and ExpressRoute gateways in the same virtual network. However, only route-based VPN gateways are supported, and certain configurations may require the use of Azure Route Server and specific settings.

4. VPN gateway types and purpose

A VPN gateway is a network device that enables secure connections between remote networks or devices and a private network, such as Azure. It allows users to establish a secure tunnel for transmitting data over the internet.

5. ExpressRoute alternatives

If ExpressRoute is not suitable for your needs, there are alternative options for virtual private networks (VPNs), such as Cisco VPN and OpenVPN, which offer different features and functionalities.

6. Number of VPN gateways per virtual network

Each virtual network (VNet) in Azure can have only one VPN gateway, which serves as the connection point for secure communication between the VNet and on-premises networks.

7. Purpose of VPN gateways

VPN gateways provide secure connectivity between multiple sites, allowing for encrypted traffic over the internet. They are commonly used to connect on-premises data centers, cloud networks, and remote offices.

8. Introduction to Azure ExpressRoute

ExpressRoute is a service provided by Azure that allows users to create private connections between Azure data centers and on-premises infrastructure. It offers a more reliable and secure option compared to VPN gateways.

9. VPN and ExpressRoute combination

While VPN gateways use the public internet to connect networks securely, ExpressRoute utilizes dedicated connections, such as leased lines or MPLS, to establish private connections between on-premises networks and Azure.

Questions and Answers

1. Does ExpressRoute require VPN gateway?

ExpressRoute does not require a VPN gateway, as it operates on a dedicated private connection.

2. What is the difference between an Azure VPN gateway and an Azure Virtual WAN?

Azure Virtual WAN is designed for large-scale VPN connections, supporting up to 1,000 branch connections per virtual hub. VPN gateways, on the other hand, are limited to 30 tunnels and are better suited for smaller-scale deployments.

3. Can I deploy both VPN and ExpressRoute gateways in the same virtual network?

Yes, it is possible to have both VPN and ExpressRoute gateways in the same virtual network. However, certain configurations and settings may be required.

4. What is the difference between VPN and VPN gateway?

VPN is a technology that allows users to establish secure connections over the internet. A VPN gateway, on the other hand, is a specific network device that serves as the connection point for VPN connections.

5. What is VPN gateway in Azure?

Azure VPN Gateway is a network device that connects your on-premises networks to Azure through secure Site-to-Site VPNs. It utilizes industry-standard protocols for secure communication.

6. What type of VPN is ExpressRoute?

ExpressRoute is not a VPN technology itself. Instead, it provides a private connection between your WAN and Microsoft services without using the public internet.

7. What are the two types of VPNs in Azure?

Azure supports three types of Point-to-Site VPN options: Secure Socket Tunneling Protocol (SSTP), OpenVPN, and IKEv2 VPN.

8. What is the alternative to ExpressRoute?

Alternative options to ExpressRoute for virtual-private-networks include Cisco VPN and Check Point VPN.

9. How many VPN gateways can each virtual network have?

Each virtual network (VNet) can have only one VPN gateway.

10. What is the purpose of a VPN gateway?

A VPN gateway enables secure connectivity between multiple sites or networks, encrypting traffic as it traverses the internet.

11. What is Azure ExpressRoute?

Azure ExpressRoute is a service that allows for private connections between Azure data centers and on-premises or colocation environments.

Now that you have a better understanding of Azure ExpressRoute and VPN gateways, you can make informed decisions about choosing the right networking option for your organization’s needs.

Does ExpressRoute require VPN gateway

Site-to-Site, Point-to-Site, and VNet-to-VNet connections all use a VPN gateway. ExpressRoute Gateway is also a specific type of Virtual Network Gateway. It sends network traffic on a dedicated private connection when configuring Azure ExpressRoute.

What is the difference between an Azure VPN gateway and an Azure Virtual WAN

How is Virtual WAN different from an Azure virtual network gateway A virtual network gateway VPN is limited to 30 tunnels. For connections, you should use Virtual WAN for large-scale VPN. You can connect up to 1,000 branch connections per virtual hub with aggregate of 20 Gbps per hub.

Can I deploy both VPN and express route gateways in same virtual network

Only route-based VPN gateway is supported.

ExpressRoute-VPN Gateway coexist configurations are not supported on the Basic SKU. If you want to use transit routing between ExpressRoute and VPN, the ASN of Azure VPN Gateway must be set to 65515, and Azure Route Server should be used.

What is the difference between VPN and VPN gateway

A VPN Client is used to search for the access provided by the VPN Gateway in order to establish a connection, building a secure tunnel to traffic data of users and corporations. In simplified language, it is a “client-server” structure (VPN Gateway is the server and VPN Client is the client).

What is VPN gateway in Azure

Azure VPN Gateway connects your on-premises networks to Azure through Site-to-Site VPNs in a similar way that you set up and connect to a remote branch office. The connectivity is secure and uses the industry-standard protocols Internet Protocol Security (IPsec) and Internet Key Exchange (IKE).

What type of VPN is ExpressRoute

ExpressRoute is a direct, private connection from your WAN (not over the public Internet) to Microsoft Services, including Azure. Site-to-site VPN traffic travels encrypted over the public Internet.

What are the two types of VPNs Azure

Azure supports three types of Point-to-site VPN options:Secure Socket Tunneling Protocol (SSTP). SSTP is a Microsoft proprietary SSL-based solution that can penetrate firewalls since most firewalls open the outbound TCP port that 443 SSL uses.OpenVPN.IKEv2 VPN.

What is the alternative to ExpressRoute
