Override settings

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)
Default:
- 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.
Default:
- Category-and-Domain
URL-To-Show-On-Override: This is where you can enter the address of an alternative URL. In the event of an override, the URL entered here will be displayed instead of the usual website. You can use this external HTML page to display your company's corporate design, for example, or to perform functions 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.. Possible values:
- Valid URL address
Default:
- Blank
Loopback-To-Use-On-Override:
- This is where you can configure an optional sender address to be used instead of the one that would normally be automatically selected for this target address. If you have configured loopback addresses you can specify them here as sender address.
Possible values:
- Name of the IP networks whose address should be used
- "INT" for the address of the first intranet
- "DMZ" for the address of the first DMZ (caution: If there is an interface called "DMZ", its address will be taken in this case)
- LB0 ... LBF for the 16 loopback addresses
- GUEST
- Any IP address in the form x.x.x.x
Default:
- Blank
Note: The sender address specified here is used unmasked for every remote station.
