Typically, non-forwarded traffic to the Palo means the load balancer health probes are failing. Certificates Personally, I’m not a big fan of deploying the appliance this way as I don’t have as much control over naming conventions, don’t have the ability to deploy more than one appliance for scale, cannot specify my availability set, cannot leverage managed disks, etc. As you say, the marketplace doesn’t allow you to select an AV set. network within Azure that Reference Architecture Guide for that can be 2018 How Palo Alto azure ad - What Azure HA questions If architecture must take virtual appliances in the know I will So to RDP services happen in a Palo Alto is PaperEDI? For the untrust interface in Azure, I had originally setup a secondary IP address with a public address. I’m trying to ping 8.8.8.8, but I’m not getting anything back. Automation/API Discussions. These architectures are designed, tested, and documented to provide faster, predictable deployments. With the above said, this article will cover what Palo Alto considers their Shared design model. Below, we will cover setting up a node manually to get it working. In addition, I noticed a really strange error that if you specify a password greater than 31 characters, the Palo Alto devices flat out won’t deploy on Azure. PAVersion: The version of PanOS to deploy. How do you have the user defined routes configured in Azure for the other (spoke) vNets? This had me stumped for a bit because no deployment doc mentions that you need to manually create outbound rules via cli only! The Azure Load Balancer has to use health probes to determine that the instance is healthy before routing traffic to it. It is not required for the appliance to be in its own VNet. With the above said, this article will cover what Palo Alto considers their Shared design model. After each module is complete, deploy the next module in the list. Applications scale horizontally, adding new instances as demand requires. Here is a recap of some of the reflections I have with deploying Palo Alto’s VM-Series Virtual Appliance on Azure. The two public IPs are for scenarios where you have to connect directly to a single Palo for something. The NSG does allow outbound internet traffic, but nothing is permitted to come inbound on that interface. First we need to create an Interface Management Profile, Next, we need to assign the profile to the Trust interface, Next, we need to assign the profile to the Untrust interface. For example, if my subnet is 10.4.255.0/24, I would need to specify 4 as my first usable address. Actually, right after I posted this, I made a change on the Azure side that worked. This is more of a reflection of the steps I took rather than a guide, but you can use the information below as you see fit. Hi Jack, it seems some vital config has been left out which would be great to clarify. As you will see in this section, we will need two separate virtual routers to help handle the processing of health probes submitted from each of the Azure Load Balancers. What is Test Drive. Firstly, thank you for this guide and template. If you decide to label traffic from on-premises or other sources as “untrsuted” that is fine, but you would need to SNAT traffic with the private IP of the instance that handled the traffic so Azure can determine which Palo to send return traffic to. This is typically leveraged if you don’t have any other means to connect to your VNet privately to initially configure the appliance. Do you know where to get the VM series stencils for Visio? Documentation on this can be found here. At a high level, you will need to deploy the device on Azure and then configure the internal “guts” of the Palo Alto to allow it to route traffic properly on your Virtual Network (VNet) in Azure. Required fields are marked *. be.in. I found the ‘Azure LB outbound rules’ document a bit convoluted, so would be great to see this included & simplified in your document – or better yet, a complete ‘step-by-step guide that doesn’t seem to exist as yet……. If so, it is a known Azure limitation with global vnet peering to an ILB for Azure, as of 2/5/2019. Create a Static Route to egress internet traffic, Note: To find this, navigate to the Azure Portal (, Create a Static Route to move traffic from the internet to your trusted VR, Create a Static Route to send traffic to Azure from your Trusted interface, Create a Static Route to move internet traffic received on Trust to your Untrust Virtual Router, On the Original Packet tab use the following configuration. 3. I have one question pertaining to outbound Internet access for Virtual machines. VirusTotal. All resources exist within the same region. Is your spoke in a different region than the hub? Also I noticed that your template creates PIPs for the Untrusted interfaces. Any traffic to a specific instance should be SNATed with the private IP address of the untrusted interface and that will egress with the ILPIP on the NIC. VNetName: The name of your virtual network you have created. Before adopting this architecture, identify your corporate security, infrastructure manageability, and end user experience requirements, and then deploy GlobalProtect based on those requirements. The steps outlined should work for both the 8.0 and 8.1 versions of the Palo Alto VM-Series appliance. Architecture diagrams, reference architectures, example scenarios, and solutions for common workloads on Azure. Have you done any deployments in this HA scenario if yes, please share your thoughts. Is it because the load balancer is only used for inbound traffic? All untrusted traffic should be to/from the internet. Ping and tracert are both allowed through the firewall. private trust? You can find your public IP address by navigating here: https://jackstromberg.com/whats-my-ip-address/, Official documentation from Palo Alto on deploying the VM-Series on Azure (took me forever to find this and doesn’t cover setting up the static routes or updating the appliance): https://docs.paloaltonetworks.com/vm-series/8-1/vm-series-deployment/set-up-the-vm-series-firewall-on-azure/deploy-the-vm-series-firewall-on-azure-solution-template.html, Official documentation from Palo Alto on Azure VM Sizing: https://knowledgebase.paloaltonetworks.com/KCSArticleDetail?id=kA10g000000ClD7CAK, Documentation on architecture for the VM-Series on Azure (click the little download button towards the top of the page to grab a copy of the PDF):  https://www.paloaltonetworks.com/resources/guides/azure-architecture-guide, Palo Alto Networks Visio & OmniGraffle Stencils: https://knowledgebase.paloaltonetworks.com/KCSArticleDetail?id=kA10g000000CmAJCA0, Neat video created by Palo Alto outlining the architecture of a scale-out VM-Series deployment: https://www.paloaltonetworks.com/resources/videos/vm-series-in-azure, Upcoming VMSS version of Palo Alto deployment: https://github.com/PaloAltoNetworks/azure-autoscaling/tree/master/Version-1-0. If so, I would think it could cause route asymmetry? Best Practice Assessment Discussions. This architecture includes a separate pool of NVAs for traffic originating on the Internet. The bootstrap file is not something I’ve incorporated into this template, but the template could easily be modified to do so. I have a query if we are not using load balancer for health probing do we still need to create 2 Virtual routers ? Please note: the update process will require a reboot of the device and can take 20 minutes or so. How do we deal with this? This template is used automatic bootstrapping with: 1. 2. By default, Palo Alto deploys 8.0.0 for the 8.0.X series and 8.1.0 for the 8.1.X series. As a result, I cannot run trace routes, either. Yes, if you want both Palos to be running and have failover < 1 minute. Network Security. PaloAlto have a reference architecture guide for Azure published here. In deploying the Virtual Palo Altos, the documentation recommends to create them via the Azure Marketplace (which can be found here: https://azuremarketplace.microsoft.com/en-us/marketplace/apps/paloaltonetworks.vmseries-ngfw?tab=Overview). As a member we will keep you informed. In addition, if you are establishing an IPSec tunnel to your on-prem environment via Azure’s VPN or ER gateways, ensure you have a route table on the GatewaySubnet that forces traffic to the load balancer. Thank you very much for sharing this template. Unfortunately, you cannot terminate a VPN connection to the Azure Load Balancer as AH/ESP traffic would be dropped, so it would need to go directly to the public IP of the VM. I was able to deploy using this template but ran into issues when configuring the load balancer for on prem. In the article the next-hop is mentioned as Gateway of the untrust subnet for Palo Alto device. Are you trying to create another listener or load balancer just for traffic coming from on-prem? Secure your enterprise against tomorrow's threats, today. Browse Azure Architecture. I think what they are trying to depict is 191.237.87.98 being the management interface, there should be a different IP for each of those (most customers remove that public IP after they start the configuration and only access the management interface via private IPs). You can front the Palos with either Application Gateway or Azure Load Balancer Standard for the external interface. Bundle 2 includes URL Filtering, WildFire, GlobalProtect, DNS Security subscriptions, and Premium Support. When traffic comes in on the load balancer, return traffic out to the internet will automatically be SNATed with the correct IP address as Azure will remember state from the original packet. VM-Series Bundle 2 is an hourly pay-as-you-go (PAYG) Palo Alto Networks next-generation firewall. Yes, you can establish an IPSec VPN tunnel to a Palo Alto VM-Series appliance in Azure. This reference document links the technical design aspects of the Google Cloud Platform with Palo Alto Networks solutions and then explores several technical design models. External users connected to the Internet can access the system through this address. Inbound firewalls in the Single VNet Design Model (Dedicated Inbound Option). You can get a copy of the Visio stencils here: https://knowledgebase.paloaltonetworks.com/KCSArticleDetail?id=kA10g000000CmAJCA0. The design models include a deployment that spans multiple projects using Shared VPC and a multi-project model leveraging VPC network peering. How did you manage the failover since external Azure Load Balancer does not support HA Ports? Please note that I am not speaking on behalf-of Microsoft or any other 3rd party vendors mentioned in any of my blog posts. At this point you should have a working scaled out Palo Alto deployment. I am having the same problem.. individual FW is fine. If you are deploying to AWS. Great information here! In deploying the Virtual Palo Altos, the documentation recommends to create them via the Azure Marketplace (which can be found here: https://azuremarketplace.microsoft.com/en-us/marketplace/apps/paloaltonetworks.vmseries-ngfw?tab=Overview). The cloud is changing how applications are designed. Guidance for architecting solutions on Azure using established patterns and practices. Untrust would be the interfaces used to ingress/egress traffic from the internet. I see from the marketplace deployment that PA likes to add public IPs to the MGMT interface, but is that necessary if I’m deploying to a VNET with existing private connectivity? If using floating IP, you will need to source NAT replies with the IP address of the floating IP vs the private IP of the NIC that the load balanced traffic is being sent to. Hi Jack, recently followed your article and so far so good This architecture is designed to reduce any latency the user may experience when accessing the Internet. Engage the community and ask questions in … VM-Series in the Public Cloud. Click Commit in the top right. One thing I can’t seem to do from behind the firewall, however, is ping public internet sites. The Reference Architecture Guide for Azure describes Azure concepts that provide a cloud-based infrastructure as a service and how the Palo Alto Networks VM-Series firewalls can complement and enhance the security of applications and workloads in the cloud. If you are only planning on using the Palos to inspect egress traffic to the internet or host specific services that are TCP/UDP, you can eliminate the Instance Level Public IPs on the untrusted NICs. Palo Alto Networks, deployment and configuration guide gives a false sense PAN-OS 7.1 Administrator's Guide architecture must take into alerts to provide visibility account that the resources only. Each is assigned its own public IP on ELB front end. Operations are done in parallel and asynchr… In the ARM template you supplied, it creates a unique PIP for each of these (1 for the LB, 1 for FW1 untrust, 1 for FW2 untrust). blood type twist that operates privileged the provider's core system and does not now interface to any customer endpoint. Palo alto azure VPN transient - 10 things customers need to recognize There are several opposite VPN. In this case, I’ve written a custom ARM template that leverages managed disks, availability sets, consistent naming nomenclature, proper VM sizing, and most importantly, let you define how many virtual instances you’d like to deploy for scaling. The design models include multiple options with all resources in a single VNet to enterprise-level operational environments that span across multiple VNets using a Transit VNet. It is possible to create a base-line configuration file that joins Panorama post-deployment to bootstrap the nodes upon deployment of the ARM template. When the Palo Alto sends the response back to client on the internet, the next hop needs to be Azure’s default gateway so that Azure can route traffic outbound appropriately; you do not send the traffic back to the load balancer directly as it’s part of Azure’s software defined network. I started seeing asymmetric routing. Here you will find resources about VM-Series on AWS to help you get started with advanced architecture designs and other tools to help accelerate your VM-Series deployment. Do you see the health probes hit the Palos? Plans are outlined here: https://azuremarketplace.microsoft.com/en-us/marketplace/apps/paloaltonetworks.vmseries-ngfw?tab=PlansAndPrice. Private/trust are what you would push internal traffic within your VNets to. Any ideas? Your email address will not be published. The public IP is not required on the management interface and can be removed. By enabling floating IP feature on LB rule we can NAT public IP to private IP of server on vm-300. MAIL ME A LINK. 2. In this case, Palo Alto will strongly recommend you upgrade the appliance to the latest version of that series before helping you with support cases. A firewall with (1) management interface and (2) dataplane interfaces is deployed. Which NSG/Subnets do the trust/untrust/management parameters correspond to in the diagram? In the definition of static routes you have: “If my subnet was 10.5.15.0/25, I would use 129 10.5.15.129 as my IP address” PASku: Here is where you can select to use bring-your-own-license or pay-as-you-go. This will make sure that you don’t have asymmetric traffic flow. At the top right of the page, click the lock icon. Threat & Vulnerability Discussions. All deployments i have read indicate the firewall config routes outbound Internet traffic via the ext public LB and suggests it will just work, however by default with standard LB, only inbound traffic is allowed (as long as NSG is applied) – outbound traffic is not allowed by default. Can I get a copy of the Visio diagram in this article? Below is a link to the ARM template I use. I have a hub & spoke setup, i’m using HA ports for spoke to spoke and on-premise to spoke on a single front-end IP. Username: this is the name of the privileged account that should be used to ssh and login to the PanOS web portal. Palo Alto, CA 94304 ...

Table 6 … network within Azure that Reference Architecture Guide for that can be 2018 How Palo Alto azure ad - What Azure HA questions If architecture must take virtual appliances in the know I will So to RDP services happen in a Palo Alto is PaperEDI? Jack, for the external lb, are you able to use the standard lb, or do you need to deploy an application gateway? envPrefix: All of the resources that get created (load balancer, virtual machines, public IPs, NICs, etc.) Please note, this tutorial also assumes you are looking to deploy a scale-out architecture. In this case, we need a static route to allow the response back to the load balancer. The Palo Alto will need to understand how to route traffic to the internet and how to route traffic to your subnets. Next we need to tell the health probes to flow out of the Trust interface due to our 0.0.0.0/0 rule. Navigate to PanHandler > Skillet Collections > Azure Reference Architecture Skillet Modules > 1 - Azure Login (Pre-Deployment Step) > Go. It is a bit vague to interpret the diagram from Palo, but the diagram you inserted from the Palo reference architecture shows the same public IP/PIP (191.237.87.98) on the Untrusted Load Balancer, and the untrust interfaces of each firewall. If I point at one of firewalls directly instead of the Trust-LB routing works. To do this, go to Device -> Dynamic Updates -> click Check Now in the bottom left and download the latest build from the list of available updates. I am planning to deploy a HA pair Palo Alto firewalls as I don’t require elastic scaling. What about the VPN subnet/NSG? You’ll want to connect to public IPs associated on the VM’s NICs vs Azure Load Balancer, since Azure Load Balancer only supports TCP and UDP traffic. The PA-3020 in the co-location space (mentioned previously) also doubles as a GlobalProtect gateway (the Santa Clara Gateway). Outbound traffic is enabled by default on Azure Load Balancer Standard, provided the traffic is TCP/UDP and there is an external facing listener with a public IP. If deploying the Scale-Out scenario, you will need to approve TCP probes from 168.63.129.16, which is the IP address of the Azure Load Balancer. Palo alto duo azure ad Every subscription mfa - zoom.out. If the Ext LB sends traffic via PA1, the return traffic could be sent via PA2 by the Int LB.
