Aviatrix Gateway to Sonicwall
This document describes how to build an IPsec tunnel based Site2Cloud connection between Aviatrix Gateway and Sonicwall.
The network setup is as follows:
VPC/VNet-AVX (with Aviatrix Gateway)
VPC/VNet CIDR: 10.0.0.0/16
On-Prem (with Sonicwall)
On-Prem Network CIDR: 10.16.100.0/24

-
Go to Gateway > New Gateway to launch an Aviatrix Gateway at the subnet (public subnet in AWS, GCP, or OCI) of VPC/VNet-AVX. Collect Gateway’s public IP addresses (35.161.77.0 in this example).
-
Go to the Site2Cloud page and click Add New to create a Site2Cloud connection.
