Summary of the Article
AWS VPN IPSec: AWS Site-to-Site VPN is a fully-managed service that creates a secure connection between your data center or branch office and your AWS resources using IP Security (IPSec) tunnels.
AWS VPN with OpenVPN: You can connect to a Client VPN endpoint and establish a VPN connection using the AWS provided client or another OpenVPN-based client application. The AWS provided client is supported on Windows, macOS, Ubuntu 18.04 LTS, and Ubuntu 20.04 LTS.
AWS VPN TCP or UDP: AWS Client VPN supports ports 443 and 1194 for both TCP and UDP.
AWS client VPN and NAT: Ensure the subnet you choose does not overlap with the resources you’ll want to access via the Client VPN endpoint. Note that Client VPN will use source NAT (SNAT) to connect to resources in the associated VPC(s).
Types of VPN in AWS: AWS VPN is comprised of two services: AWS Site-to-Site VPN and AWS Client VPN. AWS Site-to-Site VPN enables you to securely connect your on-premises network or branch office site to your Amazon Virtual Private Cloud (Amazon VPC). AWS Client VPN enables you to securely connect users to AWS or on-premises networks.
Difference between IPsec and SSL VPN in AWS: IPSec protocols apply to the network and transport layers in the middle of the OSI model. Meanwhile, SSL encrypts data on the topmost application layer. You can connect to an SSL VPN from a web browser but must install separate software to use IPSec VPNs.
OpenVPN as an SSL VPN: OpenVPN is an SSL VPN and as such is not compatible with IPSec, L2TP, or PPTP. The IPSec protocol is designed to be implemented as a modification to the IP stack in kernel space, and therefore each operating system requires its own independent implementation of IPSec.
OpenVPN as the most secure VPN: OpenVPN is an open-source, Virtual Private Network (VPN) protocol that is recognized across the industry as being the most secure VPN tunneling protocol available. It is reliable and secure because it can be implemented with strong AES encryption and strong standards for authentication.
Questions and Answers

Is AWS VPN TCP or UDP
AWS Client VPN supports ports 443 and 1194 for both TCP and UDP.
Does AWS client VPN use NAT
Ensure the subnet you choose does not overlap with the resources you'll want to access via the Client VPN endpoint. Note that Client VPN will use source NAT (SNAT) to connect to resources in the associated VPC(s).
What are the two types of VPN AWS
AWS VPN is comprised of two services: AWS Site-to-Site VPN and AWS Client VPN. AWS Site-to-Site VPN enables you to securely connect your on-premises network or branch office site to your Amazon Virtual Private Cloud (Amazon VPC). AWS Client VPN enables you to securely connect users to AWS or on-premises networks.
What is the difference between IPsec and SSL VPN AWS
IPSec protocols apply to the network and transport layers in the middle of the OSI model. Meanwhile, SSL encrypts data on the topmost application layer. You can connect to an SSL VPN from a web browser but must install separate software to use IPSec VPNs.
What type of VPN is OpenVPN
OpenVPN is an SSL VPN and as such is not compatible with IPSec, L2TP, or PPTP. The IPSec protocol is designed to be implemented as a modification to the IP stack in kernel space, and therefore each operating system requires its own independent implementation of IPSec.
Which VPN is OpenVPN
OpenVPN is an open-source, Virtual Private Network (VPN) protocol that is recognized across the industry as being the most secure VPPN tunneling protocol available. It is reliable and secure because it can be implemented with strong AES encryption and strong standards for authentication.
Does AWS use TCP
Elastic Load Balancing supports the following protocols: HTTP. HTTPS (secure HTTP) TCP.
Should VPN be UDP or TCP
TCP is more reliable, but there are many uses where UDP is preferred and this is usually the default protocol on most VPN services. UDP is a great option if you are gaming, streaming or using VoIP services. It may lose a packet or two but it won't have a huge impact on your overall connection.
What is NAT used for in AWS
A NAT gateway is a Network Address Translation (NAT) service. You can use a NAT gateway so that instances in a private subnet can connect to services outside your VPC but external services cannot initiate a connection with those instances.
Is NAT managed by AWS
NAT Gateway is a highly available AWS managed service that makes it easy to connect to the Internet from instances within a private subnet in an Amazon Virtual Private Cloud (Amazon VPC).
What are the 4 main types of VPN
The four VPN types are:Personal VPN services.Mobile VPNs.Remote access VPNs.Site-to-site VPNs.
Should I use IPsec or SSL VPN
When it comes to corporate VPNs that provide access to a company network rather than the internet, the general consensus is that IPSec is preferable for site-to-site VPNs, and SSL is better for remote access.
Is OpenVPN SSL or IPSec
Does OpenVPN support IPSec or PPTP There are three major families of VPN implementations in wide usage today: SSL, IPSec, and PPTP. OpenVPN is an SSL VPN and as such is not compatible with IPSec, L2TP, or PPTP.
Should I use OpenVPN or IPSec
OpenVPN requires extra software that the operating system (OS) usually does not have installed by default. On the other hand, IPSec is directly supported by many modern operating systems, such as Windows, Ubuntu, macOS, and Android, iOS/iPadOS and can be used out of the box.
Should I use IPSec or OpenVPN
In site-to-site connections, OpenVPN functions faster and provides more security than IPsec. IPsec encryption operates on a kernel level, whereas OpenVPN functions in user space. Therefore, in terms of endpoint performance, IPsec is more favorable.
Which is better IPSec or OpenVPN
IPSec and OpenVPN are both viable VPN solutions. But OpenVPN is generally regarded as a more secure, more flexible option. As an “always on” site-to-site VPN solution, IPSec is ideal for securing your on-premises resources, but it can be more difficult to implement with devices in the field, particularly in IoT.
What protocol does AWS use
AWS IoT Core supports standard communication protocols (HTTP, MQTT, and WebSockets and LoRaWAN are supported currently). Communication is secured using TLS. Processing data sent from connected devices.
Does AWS use TLS or SSL
AWS Certificate Manager (ACM) is a service that lets you easily provision, manage, and deploy public and private SSL/TLS certificates for use with AWS services and your internal connected resources.
What are the 3 most common VPN protocols
6 Most Common VPN Protocols1) Open VPN. OpenVPN is a highly secure and very popular protocol commonly used by many VPN providers.2) Secure Socket Tunneling Protocol (SSTP)3) Internet Key Exchange Version 2 (IKEv2)4) Wire Guard.5) Point-to-Point Tunneling Protocol (PPTP)6) Layer 2 Tunneling Protocol (L2TP)
What is the best preferred protocol for VPN
OpenVPN
What is the most secure VPN protocol Many VPN experts recommend OpenVPN as the most secure protocol. It uses 256-bit encryption as a default but also offers other ciphers such as 3DES (triple data encryption standard), Blowfish, CAST-128, and AES (Advanced Encryption Standard).
What is gateway vs NAT in AWS
Internet Gateway (IGW) allows instances with public IPs to access the internet. NAT Gateway (NGW) allows instances with no public IPs to access the internet.
Why NAT is used in AWS
A NAT gateway is a Network Address Translation (NAT) service. You can use a NAT gateway so that instances in a private subnet can connect to services outside your VPC but external services cannot initiate a connection with those instances.
What is the difference between IPSec and SSL VPN AWS
IPSec protocols apply to the network and transport layers in the middle of the OSI model. Meanwhile, SSL encrypts data on the topmost application layer. You can connect to an SSL VPN from a web browser but must install separate software to use IPSec VPNs.
