Site2Cloud (Aviatrix Gateway — PAN)

This document describes how to build an IPSec tunnel based site2cloud connection between Aviatrix Gateway and Palo Alto Netowrks (PAN) Firewall. To simulate an on-prem PAN Firewall, we use a PAN VM at AWS VPC.

Network setup is as following:

VPC1 (with Aviatrix Gateway)


VPC1 Public Subnet CIDR:

VPC1 Private Subnet CIDR:

VPC2 (with PAN-VM)


VPC2 Public Subnet CIDR:

VPC2 Private Subnet CIDR:

Configuration Workflow

1. Launch PAN-VM with at least two network interfaces - One interface serves as WAN port and is in VPC2 public subnet. The other interface serves as LAN port and is in VPC2 private subnet. Collect the public IP address of the WAN port. | 2. At Aviatrix Controller, go to Gateway->New Gateway to launch an Aviatrix Gateway at VPC1 public subnet. Collect both public and private IP address of the Gateway. | 3. At Aviatrix Controller, go to site2cloud and click Add New to create a site2cloud connection:

Field Value
VPC ID/VNet Name Choose VPC ID of VPC1
Connection Type Unmapped
Connection Name Arbitrary (e.g. avx-pan-s2c)
Remote Gateway Type Generic
Tunnel Type UDP
Algorithms Uncheck this box
Encryption over DirectConnect Uncheck this box
Enable HA Uncheck this box
Primary Cloud Gateway Select Aviatrix Gateway created above
Remote Gateway IP Address Public IP of PAN-VM WAN port
Pre-shared Key Optional (auto-generated if not entered)
Remote Subnet (VPC2 private subnet)
Local Subnet (VPC1 private subnet)

4. At Aviatrix Controller, go to site2cloud page. From site2cloud connection table, select the connection created above (e.g. avx-pan-s2c). Select Generic from Vendor drop down list and click Download Configuration button to download the site2cloud configuration. Save the configuration file for configuring PAN-VM. | | 5. Log into PAN-VM and configure it as following: | | 5.1 Go to Network->Interface->Tunnel, click Add to create a new tunnel interface and assign the following parameters.


Field Value
Interface Name tunnel.1
Virtual Router Select the existing virtual router
Security Zone Select the layer 3 internal zone from which traffic originates


If the tunnel interface is in a zone different from the one where the traffic will originate, a policy needs to be created to allow the traffic to flow from the source zone to the zone containing the tunnel interface.

5.2 Go to Network->Network Profiles->IKE Crypto, click Add and define the IKE Crypto profile (IKEv1 Phase-1) parameters.


5.3 Go to Network->Network Profiles->IKE Gateways to configure the IKE Phase-1 Gateway. These parameters should match on the site2cloud configuration downloaded at Step 4.


Field Value
Interface PAN WAN port
Peer IP Address Aviatrix Gateway public IP
Pre-shared Key Key from site2cloud configuration downloaded at Step 4
Peer Identification IP Address & Aviatrix Gateway private IP


Field Value
IKE Crypto Profile Select the profile created at Step 5.2
5.4 Under Network->Network Profiles->IPSec Crypto, click Add to create a new profile. Define the IPSec crypto profile (IKEv1 Phase-2). These parameters should match on the site2cloud configuration downloaded at Step 4.


5.5 Under Network->IPSec Tunnels, click Add to create a new IPSec Tunnel. At General window:


Field Value
Tunnel Interface Tunnel interface created at Step 5.1
IKE Gateway IKE gateway created at Step 5.3
IPSec Crypto Profile IPSec crypto profile created at Step 5.4
At Proxy IDs window:


Field Value
Local VPC2 private subnet CIDR
Remote VPC1 private subnet CIDR
Protocol Any
5.6 Under Network->Virtual Routers, click on virtual router profile, then click Static Routes, add a new route destinating to VPC1 private subnet.


Field Value
Destination VPC1 private subnet CIDR
Interface Tunnel interface created at Step 5.1
5.7 Commit the configuration.

  1. At AWS portal, configure the VPC Route Table associated with the private subnet of VPC2. Add a route destinating to VPC1 private subnet with PAN-VM LAN port as the gateway.
  2. Send traffic between VPC1 and VPC2 private subnets. At Aviatrix Controller, go to Site2Cloud page to verify the site2cloud connection status.


For troubleshooting, go to Site2Cloud->Diagnostics and select various commands from Action drop down list.
