In this article, I will discuss various aspects of VPN gateways in Azure. I will address questions related to the number of VPN gateways per virtual network, the maximum number of VPN gateways that can be created for a VNet in Azure, and the limitations on VPN connections. Additionally, I will explain the concept of transit gateways and virtual private gateways, as well as the maximum number allowed per region. Finally, I will touch upon the number of Virtual Networks that can be created per subscription and the differences between an Azure VPN gateway and an Azure Virtual WAN.
Main Thought
VPN gateways in Azure serve as a means to connect virtual networks with on-premises locations over the public internet. Each virtual network can have only one VPN gateway, but multiple connections can be established to the same gateway, allowing for connectivity between multiple networks.
Key Points
1. Multiple VPN Gateways per VNet
While it is not possible to define more than one VPN gateway per virtual network, each VPN gateway supports multiple connections. This enables the connection of multiple networks to the same VPN gateway.
2. Maximum Number of VPN Gateways
The maximum number of VPN gateways that can be created for a VNet in Azure is 30. This limit applies to both a single VPC in one region and multiple VPCs in multiple regions.
3. VPN Gateways per VPC
Each virtual private cloud (VPC) can attach only one virtual private gateway at a time. To connect a Site-to-Site VPN connection to multiple VPCs, it is recommended to use a transit gateway instead. Transit gateways allow for the aggregation of bandwidth and the connection of multiple VPCs to a central firewall or routing instance.
4. Maximum Number of Virtual Network Gateways
Each virtual network can have only one virtual network gateway. However, a single virtual network gateway can be used to configure multiple VPN connections.
5. Limitations on VPN Connections
The number of VPN connections that can be added to the server list is limited to 16, and the maximum number of concurrently active VPN connections is 4 in Azure.
Questions and Answers
1. Can you have multiple VPN gateways per VNet?
You can only define one VPN gateway per virtual network. However, each VPN Gateway supports multiple connections to it. This allows you to connect multiple networks to the same gateway.
2. Can each VNet have only one VPN gateway?
Each of the virtual networks has only one VPN gateway. Also, a VPN gateway is a specific type of virtual network gateway. However, we can create multiple connections to the same VPN gateway.
3. What is the maximum number of VPN gateways that can be created for a VNet in Azure?
A VPN gateway is a specific type of virtual network gateway that is used to send traffic between an Azure virtual network and an on-premises location over the public internet. You can also use a VPN gateway to send traffic between Azure virtual networks. Each virtual network can have at most one VPN gateway.
4. What is the maximum number of VPN gateways that can be created?
You can create at most 30 VPN gateways for one VPC in one region. You can create at most 30 VPN gateways for multiple VPCs in multiple regions.
5. How many VPN gateways per VPC?
You can attach one virtual private gateway to a VPC at a time. To connect the same Site-to-Site VPN connection to multiple VPCs, it is recommended that you explore using a transit gateway instead.
6. What is the maximum number of virtual private gateways allowed per region?
The maximum number of virtual private gateways allowed per region is 5.
7. How many customer gateways per VPC?
A VPC can have two customer gateways. You can create a VPN gateway for a virtual private cloud (VPC) and create two customer gateways for the gateway devices in the on-premises network. Then, create two IPsec-VPN connections to connect the two customer gateways to the same VPN gateway.
8. How many VNets can you have per subscription?
Each subscription allows for the creation of up to 50 Virtual Networks across all regions. VNET Peering connects two virtual networks, either in the same or different areas, and allows you to route traffic between them using private IP addresses.
9. What is the difference between an Azure VPN gateway and an Azure Virtual WAN?
A virtual network gateway VPN is limited to 30 tunnels. For connections, it is recommended to use Virtual WAN for large-scale VPN. Virtual WAN enables the connection of up to 1,000 branch connections per virtual network.
Can you have multiple VPN gateways per VNet
You can only define one VPN gateway per virtual network. However, each VPN Gateway supports multiple connections to it. This allows you to connect multiple networks to the same gateway.
Can each VNet have only one VPN gateway
Each of the virtual networks has only one VPN gateway. Also, A VPN gateway is a specific type of virtual network gateway. However, we can create multiple connections to the same VPN gateway.
What is the maximum number of VPN gateways can be created for the VNet Azure
A VPN gateway is a specific type of virtual network gateway that is used to send traffic between an Azure virtual network and an on-premises location over the public internet. You can also use a VPN gateway to send traffic between Azure virtual networks. Each virtual network can have at most one VPN gateway.

What is the maximum number of VPN gateways can be created
You can create at most 30 VPN gateways for one VPC in one region. You can create at most 30 VPN gateways for multiple VPCs in multiple regions.
How many VPN gateways per VPC
one virtual private gateway
You can attach one virtual private gateway to a VPC at a time. To connect the same Site-to-Site VPN connection to multiple VPCs, we recommend that you explore using a transit gateway instead.
How many virtual network gateways can a virtual network have
Each virtual network can have only one virtual network gateway, but one virtual network gateway can be used to configure multiple VPN connections. We will cover the following recipes in this chapter: Creating a local network gateway in the portal. Creating a local network gateway with PowerShell.
What is the maximum number of VNet Azure
Networking limits – Azure Resource Manager
| Resource | Limit |
|---|---|
| Virtual networks | 1,000 |
| Subnets per virtual network | 3,000 |
| Virtual network peerings per virtual network | 500 |
| Virtual network gateways (VPN gateways) per virtual network | 1 |
Is there a limit to the number of VPN connections
You can add VPN policies to the exception list, so that different client devices can connect to different VPN tunnels. Note： Up to 16 VPN connection profiles are allowed in the server list at the same time, the max number of concurrent active VPN connections is 4.
Can you attach multiple transit gateways to a VPC
You set up a VPC with a firewall or routing instance in the center to create a global network. In our case, you can use that as a security add-on — your firewall or edge device will be connected to multiple Transit Gateways. Finally, the use of multiple Transit Gateways allows you to aggregate bandwidth.
What is the maximum number of virtual private gateways allowed per region

How many connections can a VPN handle
Most major VPN providers allow at least five simultaneous connections per account. Some even let you connect an unlimited number of devices at the same time. However, only some VPNs let you select the specific server to which you connect (others may only let you choose the location).
Can you have multiple transit gateways
You can create multiple Transit Gateway instances per Region, and you can connect to a maximum of three Transit Gateway instances over a single Direct Connect connection for hybrid connectivity.
How many private IP addresses can you assign to an Azure virtual network
Private only: Azure reserves the first four addresses in each subnet address range, and doesn't assign the addresses. Azure assigns the next available address to a resource from the subnet address range. For example, if the subnet's address range is 10.0.
