Customize Service Routes to Services for Virtual Systems

When you enable Multi Virtual System Capability, any virtual system that does not have specific service routes configured inherits the global service and service route settings for the firewall. You can instead configure a virtual system to use a different service route, as described in the following workflow.
A firewall with multiple virtual systems must have interfaces and subinterfaces with non-overlapping IP addresses. A per-virtual system service route for SNMP traps or for Kerberos is for IPv4 only.
The service route for a service strictly follows how you configured the server profile for the service:
  • If you define a server profile (DeviceServer Profiles) for the Shared location, the firewall uses the global service route for that service.
  • If you define a server profile for a specific virtual system, the firewall uses the virtual system-specific service route for that service.
  • If you define a server profile for a specific virtual system but the virtual system-specific service route for that service is not configured, the firewall uses the global service route for that service.
The firewall supports syslog forwarding on a virtual system basis. When multiple virtual systems on a firewall are connecting to a syslog server using SSL transport, the firewall can generate only one certificate for secure communication. The firewall does not support each virtual system having its own certificate.
  1. Customize service routes for a virtual system.
    1. Select DeviceSetupServicesVirtual Systems, and select the virtual system you want to configure.
    2. Click the Service Route Configuration link.
    3. Select one:
      • Inherit Global Service Route Configuration—Causes the virtual system to inherit the global service route settings relevant to a virtual system. If you choose this option, skip the step to customize.
      • Customize—Allows you to specify a source address for each service.
    4. If you chose Customize, select the IPv4 or IPv6 tab, depending on what type of addressing the server offering the service uses. You can specify both IPv4 and IPv6 addresses for a service. Click on a service. (Only services that are relevant to a virtual system are available.)
      To easily use the same source address for multiple services, select the checkbox for the services, click Set Selected Routes, and continue.
      • To limit the drop-down list for Source Address, select a Source Interface, then select a Source Address (from that interface) as the service route. Selecting Any Source Interface makes all IP addresses on all interfaces for the virtual system available in the Source Address drop-down list from which you select an address. You can select Inherit Global Setting.
      • Source Address will indicate Inherited if you selected Inherit Global Setting for the Source Interface or it will indicate the source address you selected. If you selected Any for Source Interface, select an IP address from the drop-down, or enter an IP address (using the IPv4 or IPv6 format that matches the tab you chose) to specify the source address that will be used in packets sent to the external service.
      • If you modify an address object and the IP family type (IPv4/IPv6) changes, a Commit is required to update the service route family to use.
    5. Click OK.
    6. Repeat the prior steps to configure source addresses for other external services.
    7. Click OK.
  2. Commit your changes.
    Click Commit and OK.
    If you are configuring per-virtual system service routes for logging services for a PA-7000 Series firewall, continue to the task Configure a PA-7000 Series Firewall for Logging Per Virtual System.
