Common questions

How does the licensing work for the LANCOM Content Filter?

Licensing of the content filter is on a per-user basis. The LANCOM device determines the number of users by counting the IP addresses that are receiving filtered content. Concurrent user licensing model

 

 

How do I extend the license period for the LANCOM Content Filter?

The rating server then returns a category for this URL and, depending on how the router's content filter is configured, access to the URL will be allowed or blocked.

 

How does the LANCOM Content Filter function?

The LANCOM Content Filter uses an internal HTTP proxy to intercept URL requests and forward these to an external rating server at IBM. The rating server then returns a category for this URL and, depending on how the router's content filter is configured, access to the URL will be allowed or blocked.

 

What kind of information does the database contain, and how are web pages classified?

Domain www.domainnameindatabase.com
Host www.domainnameindatabase.com as opposed to images.domainnameindatabase.com
Directory www.domainnameindatabase.com/pics/
HTML page www.domainnameindatabase.com/pics/index.html
Image URLs www.domainnameindatabase.com/pics/001.jpg
IP address 194.12.2.3

The information stored in the database mainly consists of the URLs and the category associated with each one. Every URL in the database is given one or more pre-defined categories. The database is also capable of categorizing subpages on websites (e.g. www.this.com/media as opposed to www.this.com/erotic) and also multiple hosts for a given domain (games.appsforyou.com as opposed to finance.appsforyou.com).

Is it possible to get around the Content Filter by entering IP addresses or using host lists?

No, because the LANCOM Content Filter does not work with DNS. Instead, it checks the target of the HTTP request, irrespective of whether this is determined from the name or the IP address.

 

What is the LANCOM override and how does it work?

If enabled, the LANCOM override grants access to websites even if they are blocked. This enables access to blocked URLs for a limited period of time without having to make changes to the configuration. The LANCOM override can be activated for each category. Overrides can be logged by e-mail, syslog and SNMP.

 

Can I use my own blocking pages?

Along with the default blocking page stored in the device, which allows the displayed text to be edited and displayed in the language set in the browser, there is additionally the option of defining your own pages which can be stored on an external web server.  This page can be referenced from the configuration in the Content Filter.

 

Does the LANCOM Content Filter have an internal cache?

The LANCOM Content Filter has an internal cache as a buffer memory for the category assigned to a URL. The size of the cache depends on the device. The memory capacity can be displayed in LANmonitor.

 

Can pages be allowed or forbidden manually?

Yes, the LANCOM Content-Filter uses a blacklist and a whitelist for configuring exceptions to the usual categories. Knowledge Base article

 

Is it possible to create configurations that are time- or user based?

The LANCOM Content Filter supports time-dependent configurations for the various blocking lists (e.g. working hours vs. free time). A user-based configuration can be set up with firewall mechanisms. 

 

How many categories does the LANCOM Content Filter support?

The Content Filter supports 58 categories, which are divided into 14 subject groups.

 

Is the LANCOM Content Filter able to filter HTTPS- requests?

Yes, as of LCOS 8.50, the Content Filter is able to filter HTTPS requests. Nevertheless, the message displayed for blocked content can vary regarding the web browser and is also different from the message displayed by the HTTP request.

Does the LANCOM Content Filter provide statistics?

The LANCOM Content Filter offers an extensive range of statistics, including Top-10 lists of allowed, blocked and override URLs, counters and category listings in a configurable time frame.

 

How are URLs categorized?
