The override function allows a website to be accessed even though it is classified as forbidden. The user must click on the override button to confirm that the forbidden page should be opened. You can configure this feature so that the administrator is notified when the override button is clicked (LANconfig: Content-Filter / Global-Settings).
Note: If the override type "Category" has been activated, clicking on
the override button makes all of the categories for that URL accessible
to the user The next blocking page to be displayed has just one category
explaining why access to the URL was blocked. After clicking on the override
button, all of the allowed categories are displayed. If the override
type "Domain" has been activated, then the entire domain can be accessed.
The settings for the override function are to be found here:
LANconfig: Content-Filter / Override
WEBconfig: LCOS menu tree / Setup / UTM / Content-Filter / Global-Settings
- Override-Active This is where you can activate the override function and make further related settings.
- Override-Duration
The override duration can be restricted here. When the period expires,
any attempt to access the same domain and/or category will be blocked
again. Clicking on the override button once more allows the website to
be accessed again for the duration of the override and, depending on
the settings, the administrator will be notified once more.
Possible values:
- 1-1440 (minutes)
- 5 (minutes)
- Override-Type:
This is where you can set the type of override. It can be allowed for
the domain, for the category of website to be blocked, or for both.
Possible values:
- Category: For the duration of the override, all URLs are allowed that fall under the affected categories (as well as those which would already have been allowed even without the override).
- Domain: For the duration of the override all URLs in this domain are allowed, irrespective of the categories they belong to.
- Category-and-Domain: For the duration of the override, all URLs are allowed that belong to this domain and also to the allowed categories. This is the highest restriction.
- Category-and-Domain
- URL-To-Show-On-Override:

such as JavaScript routines, etc. You can also use the same tags here
as in the override text. If you do not make any entry here, the default
page stored in the device will be displayed..
