PAN-OS to vSRX - IKE gateways crypto profiles and proxy IDs

Connect a Palo Alto Networks firewall to a Juniper vSRX with a route-based IKEv2 tunnel, then narrow the SRX to specific traffic selectors and match them on PAN-OS with a proxy ID, reading each vendor's own view of the SAs.

Run this lab

It needs Standard: its 5 nodes are set to 7 vCPU and 11,264 MB in total.

In your workspace: Shared, then Firewalls and VPNs multi-vendor guided labs, then 05 - PAN-OS to vSRX - IKE gateways crypto profiles and proxy IDs

Run it on Standard from £5 a day

The free demo can’t run it: it has 6 vCPU and 8 GB, and this lab’s nodes need 7 vCPU and 11,264 MB together. Every lab plan includes every guided lab.

The scenario

Larkfield Media's head office runs a Palo Alto Networks firewall. Its new recording studio has a Juniper SRX. Connect the two with IKEv2. Later in the lab, Larkfield's auditors ask that the tunnel carry only the two office subnets, not "anything routed into it", so you will narrow both ends to exact traffic selectors.

What you’ll practise

  • Build PAN-OS IKE and IPsec crypto profiles, an IKE gateway, a tunnel interface and an IPsec tunnel
  • Build the matching SRX IKE gateway and route-based VPN on st0
  • Explain proxy IDs and traffic selectors, and why a route-based PAN-OS tunnel offers 0.0.0.0/0 by default
  • Add SRX traffic selectors and the matching PAN-OS proxy ID
  • Verify with show vpn ike-sa, show vpn ipsec-sa, show security ike security-associations and show security ipsec security-associations

The tasks

  1. Read the starting point
  2. PAN-OS side
  3. SRX side
  4. Narrow the selectors with a proxy ID

The Lab Tasks pane has the scenario, these tasks, the checks to run, hints and the full solution.

How to open this lab

  1. Sign in to your workspace at lab.cloudlabbox.com.

  2. In File Manager, open Shared, then the folder Firewalls and VPNs multi-vendor guided labs.

  3. Open 05 - PAN-OS to vSRX - IKE gateways crypto profiles and proxy IDs and start its nodes, then open Lab Tasks for the scenario and the steps.

The lab is read-only. You can start the nodes and configure the devices, but changes to the topology can’t be saved. To change it, rebuild it in your own folder.
