You can block or allow access to specific Web pages, by defining Web rules.
|
Note: Web rules affect outgoing traffic only and cannot be used to allow or limit access from the Internet to internal Web servers. |
The UTM-1 appliance processes Web rules in the order they appear in the Web Rules table, so that rule 1 is applied before rule 2, and so on. This enables you to define exceptions to rules, by placing the exceptions higher up in the Web Rules table.
For example, if you want to block all the pages of a particular Web site, except a specific page, you can create a rule blocking access to all of the Web site's pages and move the rule down in the Web Rules table. Then create a rule allowing access to the desired page and move this rule to a higher location in the Web Rules table than the first rule. In the figure below, the general rule is rule number 2, and the exception is rule number 1.
The UTM-1 appliance will process rule 1 first, allowing access to the desired page, and only then it will process rule 2, blocking access to the rest of the site.
The following rule types exist:
