General
For accessing the Wi-Fi from within the TUHH and the LAN of the TUHH from other Internet Providers, the RZT is hosting a VPN server. VPN is an acronym for "Virtual Private Network" and means that an encrypted connection between two points can be established (your device with VPN functionality and VPN server of TUHH).
The access works via IPSec (IP Security) and the authentication via Radius server. Because of these methods, the connection to the VPN server is completely encrypted and the user is identified. The new IP adress, which the VPN server is issuing, is contained in the IP address space of the TUHH (134.28.0.0/16). You can hereby reach the network of the TUHH over an encrypted tunnel.
This way you can use all services, which are offered within the LAN of the TUHH (sometimes called "Intranet"):
- Accessing TUHH computers, which are not reachable throught the internet (s. "Internet-Firewall")
- secured Access to the "Intranet"
- Access to library services ("digital library") and useful software
Because of technical reasons some disadvantages may occure:
- high computing effort resulting in shorter battery life
- latency → no gaming or video conferences
Regardless of whether you are connecting through an internet provider or over the Wi-Fi of the TUHH, the Cisco AnyConnect VPN Client is needed. At the notebook workspaces in the RZ, the usage of the VPN Client is mandatory as well. An alternative for PDAs is the WebVPN service of the VPN server. Through eduroam, you can also establish a connection at other universities.
