CSL Plasma GmbH - massive traffic blocks

Recommended Posts

The company CSL Plasma GmbH is a blood plasma donation company where you can donate your blood plasma in order to help people in need of it - or for research.

 

Their open Wi-Fi (for donators only, of course, but accessible for everyone) is a very special thing: It logs excessively what you are doing - outrageously much of information (browser, OS, traffic, time stamps, duration, IP addresses, websites you visit, connection details,...). To do so, it too blocks connection on most ports and protocols. I connected to their Wi-Fi network, logged in and attempted to establish a VPN connection as I'm always doing it logging into open Wi-Fi networks. Well, boom! UDP 443 didn't work.

 

So I tried with different configurations: I tried UDP/53, /80 and TCP/53, /80, /443. The only working configuration is TCP/443 (which is the standardized HTTPS port)..

Now the weird part. Internet connection seems to work for every app except for Dolphin Browser which can't manage to connect to whatever website I want it to visit. It just seems to load the websites but nothing more, nothing less. Now I don't know whether the traffic of WhatsApp for example is routed through the tunnel and hidden from their weird system.

 

If someone has got a suggestion on the problem here and/or how to circumvent this thing, feel free to post.

I don't use other browsers with Android but I will try it with Firefox the next time I will be there.

And thank you for the privacy notice! Indeed very interesting thing!

Next donation is on Thursday.

Using Firefox solved the issue. TCP/443 is working and I'm hidden, too.
