IT Attack: TU Berlin WiFi and VPN Accessible Again

updated on 23 June 2021 at 09:50

Beginning 23 June 2021, all TU staff and students must change the password to their University account to continue using the University's IT services. 

TU Berlin Campus Management will restore the use of WiFi and VPN from 23 June 2021. Both services have been overhauled to incorporate further security measures and require a new password.

Please note the following changes to WiFi and VPN access:


In order to use the University's WiFi network, you must re-install the configuration software ( Previous installations will no longer work due to changes made to the configuration. On the page, Campus Management has provided two configurations to set up WiFi on your computer or mobile device:

  • eduroam – This is the standard WiFi network for University members' mobile devices such as laptops, cell phones, or tablets. When using the eduroam profile, your device is assigned an IP address from TU Berlin's general network. You can access the general Internet e.g.
  • wlan2vlan – You can only use this network if your IT coordinator has given you special rights to access certain resources. This can include printers, scanners, servers, and computers in your unit's own decentral network. This network connects your mobile device with the TU network as if it were physically connected to a port in your office. Please note that other regulations may apply to some units (e.g. Central University Administration).

Effective immediately, VPN users can now choose between two different profiles to establish a secure connection with the TU network:

  • 1-TU-Split-Tunnel: This standard option virtually connects your device with the TU Berlin network, allowing you to access University resources including the University Library, scanners, printers, servers, and your computer at your desk. All data traffic to access TU Berlin services is routed through the VPN connection. Other applications such as streaming services or social media do not run through the University's network. Please note that other regulations may apply to some units (e.g. Central University Administration).
  • The "2-TU-Full-Tunnel" also allows users to access external services which require a TU Berlin IP address, such as literature or publisher databases provided by De Gruyter, Elsevier, Hanser, INSPEC, Nature, Nomos, Oxford University Press, Springer, Wiley, and Web of Science. When connected to this profile, all data traffic is routed through the TU Berlin network, including when using the Internet for personal use such as for audio or video streaming or social media. Please only use the full tunnel option if you intend to use the additional functions it offers in order to avoid burdening the TU Berlin network with unnecessary data volume.

You can select the relevant profile directly in the Cisco AnyConnect Secure Mobility Client VPN software each time you connect. Please use the split tunnel option if you do not need the additional functions offered by the full tunnel.
