Web filtering platform


The Web filtering platform is a solution that allows you to restrict or allow the access to a website in your network, based on some filters that you can set.
When an incoming site is about to be displayed, then the filter checks the content against rules and prevents the access if it does not meet the requirements set.

How it works

In order get the system to work, you have to:

  • set your filters in the Web Filtering platform
  • configure your router with the DNS IP addresses that you received from Cloud4Wi Team when the service was activated.

The user flow is:

  1. The user tries to open a website
  2. The browser performs the DNS lookup to the DNS servers provider by Cloud4Wi to get the IP address for the hostname entered
  3. The Web filtering platform receives the DNS request
  4. The Web filtering platform identifies the user by the source public IP address
  5. The Web filtering platform retrieves the proper settings for that user
  6. The Web filtering responds to the browser with:
    • the corresponding IP address, if the website is whitelisted
    • the DNS splash page, if the website is blacklisted
  7. The browser displays:
    • the corresponding web page, if the website is whitelisted
    • the DNS splash page, if the website is blacklisted


How to access

You can access the Content Filtering dashboard by going to http://contentfilter.cloud4wi.com/ by using your browser and then typing your username and password for the service (provided by Cloud4Wi when the service was activated).

In the paragraphs below, we are going to provide some operative steps to create a basic working configuration.

Setting up a location

To set up your location, go to Settings Location and then add your IP address.

As mentioned above, the platform is able to recognize the source of a request via the IP address. Then you have to set up your location along with all the necessary information for the platform to recognize your source IP address.

We have four options here:

  • Static IP – just provide your static IP address
  • Dynamic IP  – you require an agent to keep your IP address updated
  • Dynamic DNS – just provide your dynamic hostname
  • Roaming – you require an agent to keep your IP address updated


Setting up your policy

To set up your policy, go to Policy  Policy and then you can create or edit your policy. For each rule, in the Categories tab, you will find a list of categories and you can choose to keep them allowed (green button) or denied (red button) for the user.
The platform has a constantly updated internal database, and so your configuration will also be always up-to-date.



Once you configured your policy, you can go to Settings White/Black Lists and define any website to white or black-list.
These lists have the priority over what you have set in your policy. So for example, if you denied the category "Alcohol", then you can anyway allow the domain budweiser.com by adding it to the whitelist.

Customize your block page

You can customize your block page by going to Settings Block Page. The page is fully customizable, you can change all the text and you can also add your logo.


The platform provides you information about your web traffic and all the actions taken by the platform.
In the Dashboard (link on the top-right corner of the screen), you can find some charts about this.
In the Reporting tab, you can set your input search filter and get the history of all the traffic going through in your location. You also can export data to a PDF or XLS document.
