Aviatrix Gateway to Juniper SRX

This document describes how to build an IPsec tunnel-based Site2Cloud connection between an Aviatrix Gateway and a JuniperSRX Firewall.

The network setup is as follows:

VPC/VNet-multicloudvpc1 (with Aviatrix Gateway)

VPC/VNet CIDR: 10.1.1.0/16

VPC/VNet Subnet CIDR (public in AWS, GCP, or OCI): 10.1.1.0/24

VPC/VNet Private Subnet CIDR: 10.1.2.0/24

On-Prem (with Juniper SRX Firewall)

On-Prem Network CIDR: 10.0.0.0/16

On-prem Public Network CIDR: 10.0.3.0/24

On-prem Private Network CIDR: 10.0.2.0/24

Creating a Site2Cloud Connection at the Aviatrix Controller

  1. Go to Gateway > New Gateway to launch an Aviatrix Gateway at the subnet of VPC/VNet-multicloudvpc1 (public subnet for AWS, GCP, or OCI). Collect Gateway’s public IP addresses (3.213.233.93 in this example). image1

  2. Go to the Site2Cloud page and click Add New to create a Site2Cloud connection.

  1. Go to the Site2Cloud page. From the Site2Cloud connection table, select the connection created above (e.g. avx-SRX-S2C).
    • Select Generic from the Vendor dropdown menu.

    • Click the Download Configuration button to download the SRX Site2Cloud configuration.

    • Save the configuration file as a reference for configuring your Juniper SRX.
