ETHZ VPN with Mac OS X 10.6 "Snow Leopard" and 10.7 "Lion"

The following instructions describe how to set up the VPN with Snow Leopard's built-in VPN capabilities.

Note: The Screenshots in this Document were created with Snow Leopard, but apply to Lion as well. Differences are purely cosmetic.

Note for Snow Leopard: A bug was discovered in 10.6 and 10.6.1 which forces the user to enter his credentials each time when trying to connect the VPN, even if the password was saved. If you suffer from this misbehaviour, see the following page to correct it: OSX VPN Credentials Bug Correction.
