On the Filter Configuration page of the NetMan Settings, you can explicitly designate selected Internet pages as allowed or not allowed. In the User-defined blacklist/whitelist list, you can specify explicit Internet addresses to be permitted or blocked, in addition to the age-group defined, category-based content filtering.

Thus you can block a specific address even though it belongs to a permitted category, and vice versa: you can permit an Internet address that falls into a blocked category:
Use the buttons at the top of the list to edit the entries in the list:

Edit. Lets you edit a selected item.
Delete. Deletes the selected item.
Editing an entry in the positive/negative list
1. To create a new entry, click on the New button at the top of the list. To edit an entry, click on the Edit button at the top of the list.
2. In the Blacklist/Whitelist dialog, specify the address, the type of entry, and whether it is to be permitted or blocked:
Under URL/domain, enter the desired address. You can enter a specific URL or an Internet domain. In the Type field, specify whether you entered a URL or a domain name.
The type of an entry cannot be changed later. When you open the entry for editing, this field is grayed out.
Under Category, select the category of the item. Select Blacklist or Whitelist to have the entry added to the respective list. If you select a different category, the address is added to the existing entries in that category.
3. Click on OK to save your new entry.
