Define a profile of UTM Web filtering to be utilized at Firewall Policy.

At the Web Filter Profile, you can specify either "Blocked Categories" (Blocking per Category) or "URL Filtering" (Blocking per URL).

The Web Filter and the Global URL List have been keyed to each other as described below:
相関図

The Web Filtering defects URLs, based on the following order. If anything matched with the blocked categories, the web filtering will apply the current URL definition.
First, the URL specified by URL Filtering will be detected. In case of suggesting "Blocking", the URL will be blocked, whereas in case of suggesting "exempt", the URL will NOT be blocked.

After detection of the URL Filtering, you need to check the Global URL Lists. The URL listed up at the Blacklist will be blocked, whereas the URL listed at the Whitelist will NOT be blocked.

After checking the Global URL List, the URL has been examined whether or not the URL is defined as Blacked Categories. If so, that URL in Blacklist will be blocked.
If the URL has been done the rating as Black Categories, the URL will be blocked. Otherwise, the URL will not be blocked.

Please do NOT apply the Web Filtering to the outgoing traffics from the Proxy to the Internet. The UTM function may NOT perform correctly, due to the Proxy Scope or its settings.
