Use Case: Shared Compute Infrastructure and Shared Security Policies

This use case allows you to logically isolate traffic from two tenants that share an ESXi cluster and have a common set of security policies. In order to isolate traffic from each tenant you need to create a service definition with a template stack that includes two zones. Zone-based traffic separation makes it possible to distinguish traffic between virtual machines that belong to separate tenants, when it traverses through the firewall. The firewall is able to distinguish traffic between tenant virtual machines based on a service profiles and security groups created on the NSX-V Manager, which are available as match criteria in Dynamic Address Groups on the firewall. Therefore, even with overlapping IP addresses, you can segregate traffic from each tenant and secure each tenant’s virtual machines using zone-base policy rules (source and destination zones must be the same) and dynamic address groups.

1. Enable Communication Between the NSX-V Manager and Panorama.
   This is one-time task and is required if you have not enabled access between the NSX-V Manager and Panorama.
2. Create Template(s) and Device Group(s) on Panorama.
   1. Log in to the Panorama web interface.
   2. Select PanoramaTemplates to add a template stack. This use case has a template stack named NSX-Template.
   3. Select PanoramaDevice Groups and add device group. This use case has a device group named NSX-DG.
   4. Create two zones within the template stack. To isolate traffic for each tenant, you need two zones in this use case.
      1. Select NetworkZones.
      2. Select the correct template stack in the Template drop-down.
      3. Select Add and enter a zone Name. For example, Tenant1.
      4. Sets the interface Type to Virtual Wire.
      5. Click OK.
      6. Repeat the steps to add another zone, for example, Tenant2.
      7. Verify that the zones are attached to the correct template stack.

3. Create the Service Definitions on Panorama.
   1. Select PanoramaVMwareNSX-VService Definitions.
   2. Select Add and fill in the details.

   3. Click Commit, and select Panorama as the Commit Type to save the changes to the running configuration on Panorama.
4. Create Security Groups and Steering Rules.
   1. Select ObjectsAddress Groups and Set Up Dynamic Address Groups on Panorama for each tenant’s virtual machines. For example, this use case has two security groups per tenant; one security group for the web servers and the other security group for the application servers.
   2. Select PoliciesSecurityPre Rules to set up security policy rules for sending traffic to the VM-Series firewall.
   3. Select PanoramaVMwareNSX-VSteering Rules and click Auto-Generate Steering Rules.
   4. Commit your changes
5. Prepare the ESXi Host for the VM-Series Firewall.
   The ESXi hosts in the cluster must have the necessary NSX-V components that allow the NSX-V firewall and the VM-Series firewall to work together. The NSX-V Manager will install the components— the Ethernet Adapter Module (.eam) and the SDK —required to deploy the VM-Series firewall.
6. Deploy the Palo Alto Networks NGFW Service.
   1. Select Networking and SecurityInstallationService Deployments.
   2. Click New Service Deployment (green plus icon), and select the service definition for the Palo Alto Networks next generation firewall you want to deploy, Palo Alto Networks NGFW Test 1 in this example, make your selections including the appropriate ESXi cluster to which you want to deploy the firewall and click Finish.

   3. Verify that the NSX-V Manager reports the Installation Status as Successful.
   4. Verify that the VM-Series firewall is successfully deployed.
      1. On the vCenter server, select Hosts and Clusters to check that every host in the cluster(s) has one instance of the firewall.
      2. View the management IP address(es) and the PAN-OS version running on the firewall directly from vCenter server. VMware Tools is bundled with the PAN-OS software image and is automatically enabled when you launch the VM-Series firewall.
7. Apply Security Policies to the VM-Series Firewall.
   1. Create Dynamic Address groups for each tenant on Panorama. The dynamic address group(s) that match on the name of the security group(s) you defined on the NSX-V Manager.
      1. On Panorama, select ObjectsAddress Groups.
      2. Select the correct Device Group from the drop-down and click Add.
      3. Add a Name for the address group and set Type as Dynamic and Add Match Criteria. Verify that you select the correct tags for each tenant, the tag includes the service profile ID, the security group name and the security group ID. For example, for this use case there are four dynamic address groups:

   2. On Panorama, create security policy rules and use the dynamic address groups as source or destination address objects in security policy rules and push it to the firewalls.
      1. Select PoliciesSecurityPrerules and click Add.
      2. Create rules for each tenant. This use case has the following policy rules:

   3. Click Commit, and select Commit Type as Device Groups. Select the device group, NSX-DG in this example and click OK.
8. Verify that traffic from each tenant is secured.
   1. Log in to the CLI on the firewall and enter the following command to view the subinterfaces on the firewall:

      show interface all 
      total configured hardware interfaces: 2 
      name id    speed/duplex/state        mac address 
      --------------------------------------------------- 
      ethernet1/1             16    auto/auto/up d4:f4:be:c6:af:10 
      ethernet1/2             17    auto/auto/up d4:f4:be:c6:af:11 
      aggregation groups: 0 
      total configured logical interfaces: 6 
       
      name                id vsys zone         forwarding  
      ------------------- ----- ---- ----------------- 
      ethernet1/1      16    1                vwire:ethernet1/2  
      ethernet1/1.3    4099  1    TENANT-1   vwire:ethernet1/2.3 
      ethernet1/1.4     4100   1   TENANT-2     vwire:ethernet1/2.4  
      ethernet1/2        17    1 vwire:ethernet1/1  
      ethernet1/2.3    4355  1    TENANT-1 vwire:ethernet1/1.3  
      ethernet1/2.4      4356  1 TENANT-2 vwire:ethernet1/1.4 
       

   2. On the web interface of the VM-Series firewall, select ObjectsAddress Groups and verify that you can view the IP address for the members of each Dynamic Address Group. The following is an example of duplicate IP addresses in dynamic address groups across both tenants.

   3. View the ACC and the MonitorLogsTraffic. Filter on the zone name to ensure that traffic from the virtual machines for each tenant is secured.
