The FortiGuard-Web Filter menu contains the Override tab, Local Categories tab
and Local Ratings tab. On FortiGate units with a hard disk, you can create reports
from the Reports tab.
The Override tab provides administrators with flexibility and control when blocking
web pages. Administrators can configure override rules that allow users to access
blocked web pages, if required. Administrators can also create user-defined
categories to allow users to block groups of URLs on a per-profile basis.
From the Local Ratings tab you can configure local ratings to specify whether the
local rating is used in conjunction with the FortiGate rating or is used as an
override. The Local Categories tab allows you to specify user-defined categories
and then specify the URLs that belong to the category.
AntiSpam (formerly Spam Filter)
The Antispam menu consists of the following menus:
• Banned word
• Black/White list
You can configure additional features for FortiGate-800 units and above. In the
Banned word list you can:
• create new antispam banned word list
• view antispam banned word catalog
You can also configure the following for the FortiGate-800 and above in the
Black/White list:
• add multiple email address lists
• create new antispam email address list
• create new antispam IP address list
• view antispam IP address list catalog
The previous options available from the web-based manager in
FortiOS v2.80MR11, are now available in the CLI. See the FortiGate CLI
Reference for more information. This includes FortiGuard AntiSpam, IP Address,
DNSBL and ORDBL, MIME Headers, and Email Address.
If the MIME header check is enabled for POP3, IMAP or SMTP, and any change is
made to the Protection Profile, such as IP address check, banned word check or
logging oversized files (enabled through the web-based manager), the MIME
header check is disabled.
Also, the “clear” action for banned words in an email is now available in the CLI to
support upgrade. Since the “clear” action is no longer a valid spam action in
FortiOS 3.0, avoid using it when configuring banned words.
Note: The Black/White lists are not separate. You may need to re-enable MIME Headers
when you upgrade to FortiOS 3.0.
