To be able to use VPN to access the GFZ network you have to activate VPN on the "Passwords & Services" site on the intranet.

In case this is the first time you establish a VPN connection via ASA, you need to install the Cisco AnyConnect client. Therefore, go to https://asa.gfz-potsdam.de. As GROUP select 'GFZ-Mitarbeiter', enter your username and password and click on 'Login'.

The client will install automatically. Click on "Allow".

Enter the login password of your Mac account to begin the installation.

Start the Cisco AnyConnect Client via Launchpad.
Enter "asa.gfz-potsdam.de" as server address and click on "Connect".
