Device > Virtual Systems
A virtual system (vsys) is an independent (virtual)
firewall instance that you can separately manage within a physical
firewall. Each vsys can be an independent firewall with its own
Security policy, interfaces, and administrators; a vsys enables
you to segment the administration of all policies, reporting, and
visibility functions that the firewall provides.
For example, if you want to customize the security features for
the traffic that is associated with your Finance department, you
can define a Finance vsys and then define security policies that
pertain only to that department. To optimize policy administration,
you can maintain separate administrator accounts for overall firewall
and network functions while creating vsys administrator accounts that
allow access to an individual vsys. This allows the vsys administrator
in the Finance department to manage the Security policy for only
that department.
Networking functions (such as static and dynamic routing, IP
addresses of interfaces, and IPSec tunnels) pertain to an entire
firewall and all of its virtual systems. A virtual system configuration ()
doesn’t control firewall-level and network-level functions (such
as static and dynamic routing, IP addresses of interfaces, IPSec
tunnels, VLANs, virtual wires, virtual routers, GRE tunnels, DHCP,
DNS Proxy, QoS, LLDP and network profiles). For each vsys, you can specify
a collection of physical and logical firewall interfaces (including
VLANs and virtual wires) and security zones. If you require routing
segmentation for each vsys, you must create and assign additional
virtual routers and assign interfaces, VLANs, and virtual wires
as needed.
If you use a Panorama template to define your virtual systems,
you can configure one vsys to be the default. The default vsys and
Multi Virtual System Capability determine whether a firewall accepts
vsys-specific configurations during a template commit:
Firewalls that have Multi Virtual System Capability enabled accept
vsys-specific configurations for any vsys that is defined in the template.
Firewalls that don’t have Multi Virtual System Capability
enabled accept vsys-specific configurations only for the default
vsys. If you do not configure a default vsys, then these firewalls
will not accept vsys-specific configurations.
PA-400
Series, PA-3200 Series, PA-5200 Series, PA-5400 Series, and PA-7000
Series firewalls support multiple virtual systems. However, PA-400
Series and PA-3200 Series firewalls require a license for enabling
multiple virtual systems. The PA-220 and PA-800 Series firewalls
do not support multiple virtual systems.
Before enabling multiple virtual systems, consider the following:
A vsys administrator creates and manages all items needed for
Security policy per assigned virtual system.
Zones are objects within a vsys. Before defining a policy
or policy object, select the appropriate Virtual System from the
drop-down on the Policies or Objects tab.
You can set remote logging destinations (SNMP, syslog, and email),
applications, services, and profiles to be available to all virtual systems
(shared) or to a single vsys.
If you have multiple virtual systems, you can select a vsys
as a User-ID hub to share the IP address-to-username mapping information between
virtual systems.
You can configure globally (to all virtual systems on a firewall)
or vsys-specific service routes (
Device > Setup > Services).
You can rename a vsys only on the local firewall. On Panorama, renaming
a vsys is not supported. If you rename a vsys on Panorama, the result
is an entirely new vsys or the new vsys name gets mapped to the wrong
vsys on the firewall.
Before defining a vsys, you must first enable the multi-vsys
functionality on the firewall. Select ,
edit the General Settings, select Multi
Virtual System Capability, and click OK.
This adds a page.
Select the page, Add a vsys, and specify
the following information.
Virtual System Settings | Description |
ID | Enter an integer identifier for the vsys.
Refer to the data sheet for your firewall
model for information on the number of supported virtual systems.
If
you use a Panorama template to configure the vsys, this field does
not appear.
|
Name | Enter a name (up to 31 characters) to identify
the vsys. The name is case-sensitive and must be unique. Use only
letters, numbers, spaces, hyphens, and underscores.
If you use a Panorama template to push vsys
configurations, the vsys name in the template must match the vsys
name on the firewall.
|
Allow Forwarding of Decrypted Content | Select this option to allow the virtual
system to forward decrypted content to an outside service when port
mirroring or sending WildFire files for analysis. See also Decryption Port Mirroring. |
General Tab | Select a DNS Proxy object
if you want to apply DNS proxy rules to this vsys. ( Network > DNS Proxy). To
include objects of a particular type, select that type (interface,
VLAN, virtual wire, virtual router, or visible virtual system), Add an
object, and select the object from the drop-down. You can add one
or more objects of any type. To remove an object, select and Delete it. |
Resource Tab | Specify the following resource limits allowed
for this vsys. Each field displays the valid range of values, which
varies per firewall model. The default setting is 0, which means
the limit for the vsys is the limit for the firewall model. However,
the limit for a specific setting isn’t replicated for each vsys. 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
Limit—Maximum number of sessions.
If you
use the show session meter CLI command, the firewall
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 PA-5200
Series and PA-7000 Series firewalls, 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 results in a higher maximum per virtual system.
Security Rules—Maximum number of Security
rules. NAT Rules—Maximum number of NAT rules. Decryption Rules—Maximum number decryption
rules. QoS Rules—Maximum number of QoS rules. Application Override Rules—Maximum
number of application override rules. Policy Based Forwarding Rules—Maximum
number of policy-based forwarding (PBF) rules. - Authentication Rules—Maximum number of
authentication rules.
DoS Protection Rules—Maximum number
of denial-of-service (DoS) rules. Site to Site VPN Tunnels—Maximum number
of site-to-site VPN tunnels. Concurrent GlobalProtect Tunnels—Maximum
number of concurrent remote GlobalProtect users. Inter-Vsys User-ID Data Sharing— Configuring
a User-ID data hub requires superuser or administrator privileges. - Make this vsys a User-ID data hub—Allow
all other virtual systems on the firewall to access shared mappings.
After you enable this option, select the Mapping Type you
want to share: IP address-to-username mappings (IP User Mapping),
group mappings (User Group Mapping), or both.
- Change hub—If you want to change which vsys
is the User-ID data hub, select a new vsys to reassign that vsys
as the User-ID data hub. To stop using the vsys as a User-ID data
hub, select None.
