Maintenance on security systems of WLAN/VPN Internet connection

On Tuesday, September 20, 2022 the necessary adaptation of the WLAN/VPN firewall setup will take place in a maintenance window from 5:00 p.m. to 9:00 p.m.

Update 8:00 p.m. : The maintenance work has been completed successfully.

During the specified period, the existing firewall systems for the WLAN and VPN service will be replaced by a new modern solution that offers state-of-the-art security functions. Firewalls are still a cornerstone of any security architecture and thus make a significant contribution to increasing the security, stability and performance of the services.

All WLAN and VPN services are affected by the reconstruction; during the maintenance work, there may be interruptions in the WLAN and VPN internet connectivity to and from TUnet and its services.

We will try to keep the interruptions as short as possible and thank you for your understanding.

No changes to your end systems are necessary. If you suspect a problem after completing the maintenance work carried out, please first check the network settings of your system or contact the IT contact person at your institute. Also check the TUnet status and currently listed messages on Home. If problems persist, send an email to or contact us at 58801-42002.
