Configuring firewall policies

To add or edit a firewall policy go to 

Firewall > Policy

 and select Edit on an 

existing policy, or select Create New to add a policy.

The 

source and destination Interface/Zone

 match the firewall policy with the 

source and destination of a communication session. The Address Name matches 
the source and destination address of the communication session.

Schedule

 defines when the firewall policy is enabled. While most policies are 

always on, you can configure a firewall policy so that it is only on at specific times 
of the day. For example, you may want to block news and entertainment sites 
most of the day, except during lunch or after work, enabling your employees to 
only view those sites during non-working times.

Service

 matches the firewall policy with the service used by a communication 

session. This enables you to configure a policy for general web surfing and a 
different policy specifically for other traffic such as SMTP mail or FTP uploads and 
downloads.

Action

 defines how the FortiGate unit processes traffic. Specify an action to 

accept or deny traffic or configure a firewall encryption policy.

• Add ACCEPT policies that accept communication sessions. Using an accept 

policy, you can apply FortiGate features such as virus scanning and 
authentication to the communication session accepted by the policy.

• Add DENY policies to deny communication sessions.
• Add IPSec encryption policies to enable IPSec tunnel mode VPN traffic and 

SSL VPN encryption policies to enable SSL VPN traffic. Firewall encryption 
policies determine which types of IP traffic will be permitted during an IPSec or 
SSL VPN session.

Select 

Protection Profile

 to include apply a protection profile to the firewall policy 

for scanning of traffic passing through the FortiGate unit.

For details on the firewall policies features and settings, see the 

FortiGate 

Administration Guide

 or the FortiGate Online Help.

Antivirus options

The FortiGate unit’s antivirus configuration prevents malicious files from entering 
and infecting your network environment.

The FortiGate unit uses a number of processes to scan files to ensure unwanted 
files and potential attackers do not get through. The FortiGate unit scans using 
these antivirus options:

• File pattern - The FortiGate will check the file against the file pattern setting 

you have configured. You can set which file names or file types the FortiGate 
unit looks for in the incoming traffic.

• Virus scan - The virus definitions are kept up to date through the FortiNet 

Distribution Network. The list is updated on a regular basis so you do not have 
to wait for a firmware upgrade. Note that you must register the FortiGate unit to 
and purchase FortiGuard services to use virus scanning through the FDN.
