Establishing a connection

Please start AnyConnect from the Windows program menu. Please enter the URL of the VPN gateway in the "VPN:" field: "vpn2.zih.tu-dresden.de". After that, please click on "Connect".

In the field "Username:" please enter your "ZIH-Login@tu-dresden.de". If you want to use a license server, please enter your VPN group or your ZIH login. In the field "Password:" please enter your normal ZIH password.

In the "Group:" field, you can specify which connections should be made over the VPN. You have the following options:

A-Tunnel-TU-Networks – Connections to all networks of TU Dresden (public and private IP addresses) via VPN (recommended)
B-Tunnel-Public-TU-Networks – Connections to networks of TU Dresden with public IP adresses via VPN. Use this group, if you have problems due to overlapping private IP address space.
C-Tunnel-All-Networks – All connections (also to destinations outside of TU networks) via VPN. If all you need is a TU Dresden IP address to access online resources, consider using OpenVPN instead.
TUD-vpn-lic – Only connections to license servers (e.g. Mathcad) via VPN. Use only ZIH login name without the @-part (e.g. s1234567) in the Username field.
Other groups (Z-*, TUD-vpn-*) – These groups are for special users/requirements only, use them only if instructed to do so.

After that, please click "OK":

After the VPN connection has been successfully established, you will be assigned an IP from the associated network of the TU Dresden. The connection is displayed in the Windows task bar with a lock symbol attached.

To disconnect from the VPN, click the icon in the taskbar and then click the "Disconnect" button.
