Aviatrix Gateway to AWS VGW
Overview
This document describes how to configure an IPsec tunnel between an Aviatrix Gateway and an AWS Virtual Private Gateway (VGW).
Deployment Guide
For this use case, we will configure the AWS VGW VPN connection first and then download the configuration from AWS and import it into Aviatrix.
Create the VPN Connection
Note
Prerequisites
You have a VGW created and attached to a VPC.
You have an Aviatrix Gateway provisioned in a different VPC. You will need this gateway’s public IP address for the steps below.

Test
Once complete, test the communication using the tunnel.
Troubleshooting
Wait 2-3 minutes for the tunnel to come up. If it does not come up within that time, check the IP addresses to confirm that they are accurate. Additional troubleshooting is available in the Diagnostics tab.
Appendix: Enable HA
You can enable HA for Aviatrix Site2Cloud connection to AWS VGW. Please add the following extra steps to the configuration.
Creating an Aviatrix HA Gateway
Before creating a Site2Cloud connection, follow this guide’s Backup Gateway and Tunnel HA section to create an Aviatrix HA gateway in the same VPC.
Creating a VPN Connection Between VGW and the Aviatrix HA Gateway
From the AWS console, create a new VPN connection between VGW and Aviatrix HA Gateway.
