Content blocking

When the FortiGate unit blocks a web page, the user who requested the blocked page receives a block message and the FortiGate unit writes a message to the web filtering log.

You can add banned words to the list in many languages using Western, Simplified Chinese, Traditional Chinese, Japanese, or Korean character sets.

Adding words and phrases to the banned word list

1Go to Web Filter > Content Block.

2Select New to add a word or phrase to the banned word list.

3Choose a language or character set for the banned word or phrase.

You can choose Western, Chinese Simplified, Chinese Traditional, Japanese, or Korean.

Your computer and web browser must be configured to enter characters in the character set that you choose.

4Type a banned word or phrase.

If you type a single word (for example, banned), the FortiGate unit blocks all web pages that contain that word.

If you type a phrase (for example, banned phrase), the FortiGate unit blocks web pages that contain both words. When this phrase appears on the banned word list, the FortiGate unit inserts plus signs (+) in place of spaces (for example, banned+phrase).

If you type a phrase in quotes (for example, “banned word”), the FortiGate unit blocks all web pages in which the words are found together as a phrase.

Content filtering is not case-sensitive. You cannot include special characters in banned words.

5Select OK.

The word or phrase is added to the banned word list.

6In the Modify column, check the box beside the new item in the banned word list so that the FortiGate unit blocks web pages containing this word or phrase.

You can enter multiple banned words or phrases and then select Check All to activate all items in the banned word list.

Note: Banned Word must be selected in the content profile for web pages containing banned words to be blocked.
