reference architecture guide for azure palo alto

By default, Palo Alto deploys 8.0.0 for the 8.0.X series and 8.1.0 for the 8.1.X series. HA Ports is not required for the external load balancer. Thanks for putting this together. VM-Series Bundle 2 is an hourly pay-as-you-go (PAYG) Palo Alto Networks next-generation firewall. Untrust would be the interfaces used to ingress/egress traffic from the internet. Quick question for you: I have this all setup, and the Palo Alto in Azure is successfully filtering traffic. I started seeing asymmetric routing. Management is kind of obvious, but is public untrust? DNS, Azure Monitor, Cisco ASA, Palo Alto Networks, Azure AD, Azure Activity, AWS: Full Admin policy created and then attached to Roles, Users, or Groups: AWS: Failed AzureAD logons but success logon to AWS Console: Azure AD, AWS: Failed AWS Console logons but success logon to AzureAD: Azure AD, AWS: MFA disabled for a user: Azure AD, AWS Could you please provide me the configuration on the Public LB to pick the traffic from Gateway of the untrust subnet. Solved: Dear All, In the AWS Reference Architecture Guide, P43 'IP addresses 10.100.10.10 and 10.100.110.10 provide two paths for the - 349297 For example, let’s say you were to establish a VPN connection directly to the Palo’s, you wouldn’t be able to do that through the Azure Load Balancer. Architecture diagrams, reference architectures, example scenarios, and solutions for common workloads on Azure. PaloAlto have a reference architecture guide for Azure published here. As you say, the marketplace doesn’t allow you to select an AV set. I'm trying to assess the available approaches for a resilient Azure Palo Alto deployment and though I'd cast a net here for anyone who has had experiences, good or bad. Why 129? Palo alto duo azure ad Every subscription mfa - zoom.out. The outbound rules are recommended and are useful when you want to explicitly define how traffic should egress from the backend pool, but is not required. manPrivateIPFirst, trustPrivateIPFirst, untrustPrivateIPFirst: The first usable IP address on the subnet specified. Threat & Vulnerability Discussions. AWS Reference Architecture Guide - Palo Alto Networks. The steps outlined should work for both the 8.0 and 8.1 versions of the Palo Alto VM-Series appliance. I was able to deploy using this template but ran into issues when configuring the load balancer for on prem. PACount: This defines how many virtual instances you want deployed and placed behind load balancers. 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. Note: Disabling this option ensures that traffic handled by this interface does not flow directly to the default gateway in the VNet. If so, it is a known Azure limitation with global vnet peering to an ILB for Azure, as of 2/5/2019. By enabling floating IP feature on LB rule we can NAT public IP to private IP of server on vm-300. 2. In the article the next-hop is mentioned as Gateway of the untrust subnet for Palo Alto device. 3. PaloAlto VM's can be bootstrapped by configuring the CustomData field in the ARM template, which contains the details of an Azure file share that contains special configuration files. I guess my question is 1) Why do the untrust interface of the firewalls need a PIP? Welcome to the Palo Alto Networks VM-Series on AWS resource page. Your email address will not be published. manPrivateIPPrefix, trustPrivateIPPrefix, untrustPrivateIPPrefix: Corresponding subnet address range. The public IP is not required on the management interface and can be removed. Hi Jack, it seems some vital config has been left out which would be great to clarify. Alternatively, you can click this button here: Here are some notes on what the parameters mean in the template: VMsize: Per Palo Alto, the recommend VM sizes should be DS3, DS4, or DS5. This architecture is designed to reduce any latency the user may experience when accessing the Internet. Note: this article doesn’t cover the concept of using Panorama, but that would centrally manage each of the scale-out instances in a “single pane of glass”. This will make sure that you don’t have asymmetric traffic flow. As per Azure Load Balancer’s documentation, you will need an NSG associated to the NICs or subnet to allow traffic in from the internet. Please note: the update process will require a reboot of the device and can take 20 minutes or so. Network Security. Here is a recap of some of the reflections I have with deploying Palo Alto’s VM-Series Virtual Appliance on Azure. envPrefix: All of the resources that get created (load balancer, virtual machines, public IPs, NICs, etc.) Do you know where to get the VM series stencils for Visio? This had me stumped for a bit because no deployment doc mentions that you need to manually create outbound rules via cli only! Which NSG/Subnets do the trust/untrust/management parameters correspond to in the diagram? VM-Series Next-Generation Firewall from Palo Alto Networks Palo Alto Networks, Inc. All incoming requests from the Internet pass through the load balancer and ar… PASku: Here is where you can select to use bring-your-own-license or pay-as-you-go. Our setup is ELB–>VM300 x2 –>VNETs. The Palo Alto will need to understand how to route traffic to the internet and how to route traffic to your subnets. 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. 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. Can I get a copy of the Visio diagram in this article? Any ideas? 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. Thank you for writing a nice article. I’ve been in a whole world of pain simply trying to deploy two HA firewalls. 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? 2. Application state is distributed. Automation/API Discussions. Why is that? Must be 31 characters or less due to Pan OS limitation. Browse Azure Architecture. The two public IPs are for scenarios where you have to connect directly to a single Palo for something. i have a pair of Pans running in azure. This is typically leveraged if you don’t have any other means to connect to your VNet privately to initially configure the appliance. 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. 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). 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. After each module is complete, deploy the next module in the list. Your email address will not be published. Applications scale horizontally, adding new instances as demand requires. Each is assigned its own public IP on ELB front end. Next we need to tell the health probes to flow out of the Trust interface due to our 0.0.0.0/0 rule. Is this only an issue with Ext LB or same issue with Int LB subnet to subnet ? You should only use the single trusted/internal load balancer for both azure and on-prem traffic (this will ensure traffic symetry). The IP address of the public endpoint. 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. In this case, we need a static route to allow the response back to the load balancer. 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. 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. Jack, for the external lb, are you able to use the standard lb, or do you need to deploy an application gateway? 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. 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. Copyright © 2021 Palo Alto Networks. The diagram has 3 public IPs; one public IP on each instance and one public IP on the load balancer. How do we deal with this? I have read & been told of the possibility of asymmetric routing & hoping you could clarify. Great information here! At this point you should have a working scaled out Palo Alto deployment. Click Commit in the top right. Yes, you can establish an IPSec VPN tunnel to a Palo Alto VM-Series appliance in Azure. 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. 129 is not part of 10.5.15.0/25 . But in your diagram i can see two front-end IPs. Also I noticed that your template creates PIPs for the Untrusted interfaces. If you are looking for a single instance, you can still follow along.
