How does AWS VPN works?

Summary of the article:

In this article, we will explore various aspects of AWS VPN. AWS Client VPN uses the secure TLS VPN tunnel protocol to encrypt the traffic. Open the Amazon VPC console to run AWS VPN. A Site-to-Site VPN connection consists of a virtual private gateway or a transit gateway, a customer gateway device, and a customer gateway. To check if your AWS VPN is working, sign in to the Amazon VPC console, select your VPN connection, and review the tunnel details. AWS Client VPN supports ports 443 and 1194 for both TCP and UDP. The difference between VPC and VPN in AWS is that a VPC is a private network on the cloud while a VPN gateway is created in a VPC and is the access point of a VPN connection. To set up your own AWS VPN, sign up for an AWS account, copy and paste a new IAM role for VPN, create a new EC2 instance, connect to the instance, clone Algo VPN, run setup scripts, and copy the auto-generated VPN config to your client. The key differences between AWS Direct Connect and VPN are that Direct Connect provides a consistent experience, while VPN is connected with shared and public networks, causing fluctuating bandwidth and latency. VPCs create a private network within a public cloud environment, while VPNs offer secure remote access to those resources. AWS VPN has two tunnels in a Site-to-Site VPN connection to provide increased availability. To check if a VPN is active, turn off the VPN and visit WhatIsMyIPAddress.com to check your public IP address, then turn on the VPN and connect to a server in your chosen location and check your IP address again.

Questions and Detailed Answers:

1. What type of VPN does AWS use?
AWS Client VPN uses the secure TLS VPN tunnel protocol to encrypt the traffic. A single VPN tunnel terminates at each Client VPN endpoint and provides users access to all AWS and on-premises resources.

2. How do I run AWS VPN?
Open the Amazon VPC console at https://console.aws.amazon.com/vpc/. In the navigation pane, choose Site-to-Site VPN connections. Select your VPN connection and choose Download configuration. Select the Vendor, Platform, Software, and IKE version that correspond to your customer gateway device. Choose Download.

3. What are two components of an AWS VPN connection?
A Site-to-Site VPN connection consists of a virtual private gateway or a transit gateway and a customer gateway device.

4. How do I know if my AWS VPN is working?
Sign in to the Amazon VPC console. In the navigation pane, under Site-to-Site VPN Connections, choose Site-to-Site VPN Connections. Select your VPN connection. Choose the Tunnel Details view. Review the Status of your VPN tunnel. If the tunnel status is UP, then choose the Static Routes view.

5. Is AWS VPN TCP or UDP?
AWS Client VPN supports ports 443 and 1194 for both TCP and UDP.

6. What is the difference between VPC and VPN in AWS?
A VPC is a private network on the cloud, while a VPN gateway is created in a VPC and is the access point of a VPN connection.

7. How do I setup my own AWS VPN?
Just do it (yourself)! Sign up for an AWS account (free tier optional), copy and paste a new IAM role for VPN (provided by Algo), create a new EC2 instance, connect to the instance, clone Algo VPN, run setup scripts, and copy the auto-generated VPN config over to your client (laptop, phone, etc).

8. What is the difference between AWS Direct Connect and VPN?
The key differences between AWS Direct Connect and VPN are that Direct Connect provides a consistent experience, while VPN is connected with shared and public networks, causing the bandwidth and latency to fluctuate.

9. What is the difference between VPC and VPN?
While VPCs create a private network within a public cloud environment, VPNs offer secure access to those resources remotely. Both VPCs and VPNs provide numerous benefits, including enhanced security, privacy protection, remote access, and bypassing geo-restrictions.

10. Why does AWS VPN have two tunnels?
A Site-to-Site VPN connection consists of two tunnels, each terminating in a different Availability Zone, to provide increased availability to your VPC. If there’s a device failure within AWS, your VPN connection automatically fails over to the second tunnel so that your access isn’t interrupted.

11. How do I know if VPN is active?
To check if a VPN is working, turn off your VPN and visit WhatIsMyIPAddress.com to see your public IP address assigned by your ISP. Turn on the VPN and connect to a server in your chosen location. Check your IP address again using the same method as before.

The key differences between AWS Direct Connect and VPN

Is a VPC the same as a VPN

A Virtual Private Cloud (VPC) allows you to virtually create a private and isolated network in the cloud. Just as a virtual private network (VPN) provides secure data transfer over the public Internet, a VPC provides secure data transfer between a private enterprise and a public cloud provider.

How many VPNs per VPC

You can attach only one internet gateway to a VPC at a time.

What is the difference between AWS client VPN and VPN gateway

Client-to-Site VPN. That's roughly the difference between site to site and client to site VPNs. In AWS the VPN Gateway uses IPsec protocol and the Client VPN uses OpenVPN protocol but that's just how AWS implemented the services. However in general it's perfectly possible to use either protocol in either setup.

What happens when VPN is activated

A VPN connection establishes a secure connection between you and the internet. Via the VPN, all your data traffic is routed through an encrypted virtual tunnel. This disguises your IP address when you use the internet, making its location invisible to everyone. A VPN connection is also secure against external attacks.
