Configure Virtual Systems
Creating a virtual system requires that you have the following:
- Asuperuseradministrative role.
- An interface configured.
- Enable virtual systems.
- Selectand edit theDeviceSetupManagementGeneral Settings.
- Select theMulti Virtual System Capabilitycheck box and clickOK. This action triggers a commit if you approve it.Only after enabling virtual systems will theDevicetab display theVirtual SystemsandShared Gatewaysoptions.
- Create a virtual system.
- Select, clickDeviceVirtual SystemsAddand enter a virtual systemID, which is appended to “vsys” (range is 1-255).The default isvsys1. You cannot delete vsys1 because it is relevant to the internal hierarchy on the firewall; vsys1 appears even on firewall models that don’t support multiple virtual systems.
- SelectAllow forwarding of decrypted contentif you want to allow the firewall to forward decrypted content to an outside service. For example, you must enable this option for the firewall to be able to send decrypted content to WildFire for analysis.
- Enter a descriptiveNamefor the virtual system. A maximum of 31 alphanumeric, space, and underscore characters is allowed.
- Assign interfaces to the virtual system.The virtual routers, virtual wires, or VLANs can either be configured already or you can configure them later, at which point you specify the virtual system associated with each.
- On theGeneraltab, select aDNS Proxyobject if you want to apply DNS proxy rules to the interface.
- In theInterfacesfield, clickAddto enter the interfaces or subinterfaces to assign to the virtual system. An interface can belong to only one virtual system.
- Do any of the following, based on the deployment type(s) you need in the virtual system:
- In theVLANsfield, clickAddto enter the VLAN(s) to assign to the vsys.
- In theVirtual Wiresfield, clickAddto enter the virtual wire(s) to assign to the vsys.
- In theVirtual Routersfield, clickAddto enter the virtual router(s) to assign to the vsys.
- In theVisible Virtual Systemfield, check all virtual systems that should be made visible to the virtual system being configured. This is required for virtual systems that need to communicate with each other.In a multi-tenancy scenario where strict administrative boundaries are required, no virtual systems would be checked.
- (Optional) Limit the resource allocations for sessions, rules, and VPN tunnels allowed for the virtual system. The flexibility of being able to allocate limits per virtual system allows you to effectively control firewall resources.
- On theResourcetab, optionally set limits for a virtual system. Each field displays the valid range of values, which varies per firewall model. The default setting is 0, which means the limit for the virtual system is the limit for the firewall model. However, the limit for a specific setting isn’t replicated for each virtual system. For example, if a firewall has four virtual systems, each virtual system can’t have the total number of Decryption Rules allowed per firewall. After the total number of Decryption Rules for all of the virtual systems reaches the firewall limit, you cannot add more.
- Sessions LimitIf you use the show session meter CLI command, it displays the Maximum number of sessions allowed per dataplane, the Current number of sessions being used by the virtual system, and the Throttled number of sessions per virtual system. On a PA-5200 or PA-7000 Series firewall, the Current number of sessions being used can be greater than the Maximum configured for Sessions Limit because there are multiple dataplanes per virtual system. The Sessions Limit you configure on a PA-5200 Series or PA-7000 Series firewall is per dataplane, and will result in a higher maximum per virtual system.
- Security Rules
- NAT Rules
- Decryption Rules
- QoS Rules
- Application Override Rules
- Policy Based Forwarding Rules
- Authentication Rules
- DoS Protection Rules
- Site to Site VPN Tunnels
- Concurrent SSL VPN Tunnels
- Commit the configuration.ClickCommit. The virtual system is now an object accessible from theObjectstab.
- Create at least one virtual router for the virtual system in order to make the virtual system capable of networking functions, such as static and dynamic routing.Alternatively, your virtual system might use a VLAN or a virtual wire, depending on your deployment.
- SelectandNetworkVirtual RoutersAdda virtual router byName.
- ForInterfaces, clickAddand from the drop-down, select the interfaces that belong to the virtual router.
- Configure a security zone for each interface in the virtual system.
- Configure the security policy rules that allow or deny traffic to and from the zones in the virtual system.
- Commit the configuration.ClickCommit.After creating a virtual system, you can use the CLI to commit a configuration for only a specific virtual system:commit partial vsys<vsys-id>
- (Optional) View the security policies configured for a virtual system.Open an SSH session to use the CLI. To view the security policies for a virtual system, in operational mode, use the following commands:set system setting target-vsys<vsys-id>show running security-policy
