I’ve been using a VPN (Virtual Private Network) with my iPhone and iPad in connection with my FRITZ!Box 6360 for a long while. The VPN via a free dyndns.org account (offer of free accounts in the mean time discontinued!) worked perfectly together with my iPhone 4S and my iPad 4 till a couples of day ago. But then it was not possible to connect my iPhone or iPad to the internet. I checked my FRITZ!Box VPN settings when I was back in my home network, but I couldn’t find any hint to solve the problem. The VPN connection was correctly established, which I tested again via mobile network with my iPhone (I disconnected WiFi!).
So what to do next? Correctly, i went googling and found the solution in the german forum iszene.com: The user Athensboy reported the solution which I immediately tested on my FRITZ!Box:
- Go to your Fritz!Box
- Go to settings ‘Internet’.
- Go to ‘Filter’.
- Switch to ‘Lists’.
- Turn off ‘NetBIOS’ and save.
- Turn on ‘NetBIOS’ again and save, too.
Now the internet via VPN should work on your iPhone or iPad again. I do not really know how this solutions works, but it does!
