SwissVPN connection through OpenVPN (iPhone / iPad)
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 iOS.
