Configure the Service Infrastructure
Before you can begin setting up Prisma Access to secure your remote networks and/or mobile users, you must configure an infrastructure subnet, which Prisma Access will use to create the network backbone for communication between your service connections, remote networks, and mobile users, as well as with the corporate networks you plan to connect to Prisma Access over service connections. Because a large number of IP addresses will be required to set up the infrastructure, you must use a /24 subnet (for example, 172.16.55.0/24) at a minimum. Be sure you follow all guidelines and requirements.
- Selectand click the gear icon to edit the Settings.PanoramaCloud ServicesConfigurationService Setup
- On theGeneraltab, specify anInfrastructure Subnetthat meets the requirements, for example, 172.16.55.0/24.
- (Optional) If you want to enable Prisma Access to use BGP to dynamically discover routes to resources on your remote networks and HQ/data center locations, enter theInfrastructure BGP ASyou want to use within the Prisma Access infrastructure.If you do not supply an AS number, the default AS number 65534 will be used.
- The templates you add here can help simplify the process of adding new service connections. For example, if you add a template containing existing IPSec configuration settings, such as IPSec tunnel, Tunnel Monitoring, and IPSec Crypto Profile configurations, you can select these configurations when defining the tunnel settings for each service connection rather than having to create the tunnel configuration from scratch. You can optionally edit the predefined Service_Conn_Template with tunnel settings that you can leverage when creating the tunnels from Prisma Access to your corporate network sites.
- (Optional) Enable Prisma Access to resolve your internal domains using your corporate DNS servers.Use this step if you need Prisma Access to be able to resolve your internal domains to access services, such as LDAP servers, on your corporate network via service connections. For example, if you want a DNS lookup for your corporate domain to go exclusively to the corporate DNS server, specify the corporate domain and the corporate DNS servers here.
- Select theInternal Domain Listtab.
- AddtheDomain Names,Primary DNS, andSecondary DNSservers that you want Prisma Access to use to resolve your internal domain names.You can use a wildcard (*) in front of the domains in the domain list, for example *.acme.local or *.acme.com.
- Enable Cortex Data Lake.
- Select theCortex Data Laketab.
- Select aCortex Data Lake Theaterand clickOK.
- Configure the device groups you are using to push settings to Prisma Access with a Log Forwarding profile that forwards the desired log types toPanorama/Cortex Data Lake.The Cloud Services plugin automatically adds the following Log Settings () after a new installation or when removing non-Prisma Access templates from a Prisma Access template stack:DeviceLog Settings
These Log Setting configurations automatically forward System, User-ID, HIP Match, and GlobalProtect logs to Cortex Data Lake.To apply log setting changes, perform the following steps, then commit and push your changes:
- Log Settings for System logs (system-gpcs-default), User-ID logs (userid-gpcs-default), HIP Match logs (hipmatch-gpcs-default), and GlobalProtect logs (gp-prismaaccess-default) are added to the Mobile_User_Template.
- Log Settings for System logs (system-gpcs-default), User-ID logs (userid-gpcs-default), and GlobalProtect logs (gp-prismaaccess-default) are added to the Remote_Network_Template.
- Log Settings for System logs (system-gpcs-default) and GlobalProtect logs (gp-prismaaccess-default) are added to the Service_Conn_Template.
The way you enable log forwarding for other log types depends on the type. For logs that are generated based on a policy match, use a log forwarding profile. See the Cortex Data Lake Getting Started Guide for more information.
- To apply the log setting to the mobile user template, select, click the gear icon to edit the settings, and click OK.PanoramaCloud ServicesConfigurationMobile Users
- To apply the log setting to the remote network template, select, click the gear icon to edit the settings, and click OK.PanoramaCloud ServicesConfigurationRemote Networks
- To apply the log setting to the service connection template, select, click the gear icon to edit the settings, and click OK.PanoramaCloud ServicesConfigurationService Setup
- If you use URLs in EDLs or custom URL categories and do not append a forward slash (/) to the URL, it is possible to allow more URLs than you intended. For example, enteringexample.comas a matching URL instead ofexample.com/would also match example.com.website.info or example.com.br.By selectingAppend the ending token to the URLs in the URL filtering configuration, Prisma Access sets an ending token to URLs in EDLs or custom URL categories so that, if you enterexample.com, Prisma Access treats it as it would treat example.com/ and only matches that URL.
- (Optional) ConfigureAdvancedsettings (routing preferences, symmetric network path options for service connections, and HIP redistribution).
- Specify theRouting Preferenceto use with service connections.You can specify network preferences to use either your organization’s network, or the Prisma Access network, to process the service connection traffic.
Changing the Prisma Access service connection routing method requires a thorough understanding of your organization’s topology and routing devices, along with an understanding of how Prisma Access routing works. We recommend that you read Routing for Service Connection Traffic carefully before changing the routing method from default.
- Default—Prisma Access uses default routing in its internal network.
- Hot potato routing—Prisma Access hands off service connection traffic to your organization’s WAN as quickly as possible.
- Configure theBackbone Routingto use for the service connections.By default, the Prisma Access backbone requires that you have a symmetric network path for the traffic returning from the data center or headquarters location by way of a service connection. If you want to use ECMP or another load balancing mechanism for service connections from your CPE, you can enable asymmetric flows through the Prisma Access backbone.
- Selectno-asymmetric-routingto require symmetric flows across the service connection backbone (the default setting).
- Selectasymmetric-routing-onlyto allow Prisma Access to use asymmetric flows across the service connection backbone.
- If you have multiple service connections to a location, you can take advantage of load balancing in your Prisma Access deployment by selectingasymmetric-routing-with-load-share. However, load balancing is done on a best-effort basis, and load balancing will fail if one of the service connections goes down.
- Enable HIP Redistribution to use service connections to redistribute HIP information from mobile users and users at remote networks.
- Withdraw Static Routes if Service Connection or Remote Network IPSec tunnel is downif you want Prisma Access to remove static routes when a tunnel goes down without a backup tunnel.Prisma Access removes the route in the following situations:
- The primary tunnel goes down and there is no secondary tunnel.
- If a primary and secondary tunnel is configured, but both go down.
- (Optional) If you want to route remote network and service connection IPSec tunnel packets to the static IKE gateways over the internet,Enable automatic IKE peer host routes for Remote Networks and Service Connections.
- (Optional)Specify Outbound Routes for the Service (Max 10)by adding up to 10 prefixes for which Prisma Access adds static routes on all service connections and remote network connections. Prisma Access then routes traffic to these prefixes over the internet.
- ClickOKto save the Service Setup settings.
- Commit all your changes to Panorama and push the configuration changes to Prisma Access.
- Click.CommitCommit to Panorama
- Clickand clickCommitPush to DevicesEdit Selections.
- On thePrisma Accesstab, make sureService setupis selected and then clickOK.Prisma Access should automatically select the components that need to be committed.
- Verify that Prisma Access is successfully connected to Cortex Data Lake.
