As an alternative to the standard PPTP VPN connection, SwissVPN now operates
a service using OpenVPN. While PPTP is still the recommended protocol,
OpenVPN may be able to pass through firewalls and proxy servers where PPTP cannot get through.
The OpenVPN configuration for SwissVPN only requires outbound TCP connections
on port 443 to be allowed (and a working DNS service, of course).
The following instructions explain how to install OpenVPN on a Windows XP, Vista or 7 machine.
OpenVPN is also available for many other operating systems (including Mac OS X and Linux); you should only
need the configuration file and CA certificate (see step 5 below).
Install OpenVPN with the default settings (just keep pressing "Next" and leave any installation options at the defaults). When Windows asks whether you want to install the "TAP-Win32 Adapter V9", choose "Install" or "Continue Anyway".
