Connect the Firewall to the WildFire Appliance VM Interface

Configure the interface on the firewall that the VM interface will connect to and set the virtual router.
The wf-vm-zone should only contain the interface (ethernet1/3 in this example) used to connect the VM interface on the appliance to the firewall. This is done to avoid having any traffic generated by the malware from reaching other networks.
From the web interface on the firewall, select
Network
Interfaces
and then select an interface, for example
Ethernet1/3
.
In the
Interface Type
drop-down, select
Layer3
.
On the
Config
tab, from the
Security Zone
drop-down box, select
New Zone
.
In the Zone dialog
Name
field, enter wf-vm-zone and click
OK
.
In the
Virtual Router
drop-down box, select
default
.
To assign an IP address to the interface, select the
IPv4
tab, click
Add
in the IP section, and enter the IP address and network mask to assign to the interface, for example 10.16.0.0/22.
To save the interface configuration, click
OK
.
Create a security policy on the firewall to allow access from the VM interface to the Internet and block all incoming traffic. In this example, the policy name is WildFire VM Interface. Because you will not create a security policy from the Untrust zone to the wf-vm-interface zone, all inbound traffic is blocked by default.
Select
Policies
Security
and click
Add
In the
General
tab, enter a
Name
.
In the
Source
tab, set the
Source Zone
to
wf-vm-zone
.
In the
Destination
tab, set the
Destination Zone
to
Untrust
.
In the
Application
and
Service/ URL Category
tabs, leave the default as
Any
.
In the
Actions
tab, set the
Action Setting
to
Allow
.
Under
Log Setting
, select the
Log at Session End
check box.
If there are concerns that someone might inadvertently add other interfaces to the wf-vm-zone, clone the WildFire VM Interface security policy and then in the
Action
tab for the cloned rule, select
Deny
. Make sure this new security policy is listed below the WildFire VM interface policy. This will override the implicit intra-zone allow rule that allows communications between interfaces in the same zone and will deny/block all intra-zone communication.
Connect the cables.
Physically connect the VM interface on the WildFire appliance to the port you configured on the firewall (Ethernet 1/3 in this example) using a straight through RJ-45 cable. The VM interface is labeled
1
on the back of the appliance.
