FritzBox users: protect your network for free!

If you are living in Germany, Austria or Switzerland, there is a high chance that you are using one of the AVM’s FritzBox for your broadband connection.

The FritzBox is a very small device which runs a PowerPC processor and between 16 and 32 MB RAM. This is almost nothing!

So, you can’t install antivirus or some security solution to filter the URLs you visit via this device.

There is, however, a very easy and good way to protect your network.

All new models of FritzBox have the possibility to set a special DNS server which can be used for various other purposes, other than simple DNS.

For example, using OpenDNS you can filter the DNS requests which point to malware, phishing and other potentially unwanted websites (a basic parental control).

The good part is that it is very, very simple to configure this great feature.

Here is how in English/German:

  1. Login on your fritz.box/
  2. Go to Internet->Connection data / Internet->Zugangsdaten
  3. Click on DNS Server / Klick auf DNS-Server
  4. Choose Alternative DNS Server / Wähle “Andere DNSv4-Server
  5. Write the IPs: / Schreibe diese IP Adressen:

208.67.222.222

8.8.8.8

fritzbox-dns

  1. Click on Apply / Klick auf Übernehmen

The 8.8.8.8 is the Google DNS server which has also a good protection against malware and phishing.

The 208.67.222.222 is from OpenDNS and this one will be used as primary DNS server.

If you notice that browsing is too slow (which should not happen), then you can switch the two IP addresses.

 

If you have children who go online you might actually want to use the parental control features of FritzBox.

Have fun browsing safely from all your devices!
