Download the client program and run it. When you run it, you should see a security prompt showing that this program is a legitimate product of Psiphon Inc.
Psiphon 3 automatically starts connecting when you run it. While it is connecting, a spinning icon is displayed.
When the green icon is displayed, all of your Internet traffic is flowing through Psiphon 3.
When you close the program, Psiphon 3 automatically disconnects. You can also click on the icon to toggle the connection.
Sometimes the VPN protocol is blocked and, after a 20 second connection timeout, Psiphon 3 automatically falls back to offering an HTTP Proxy and SOCKS Proxy over an SSH tunnel. In this mode, not all of your Internet traffic flows through Psiphon 3, just certain applications. Psiphon 3 automatically sets the Windows system proxy settings that are respected by default by all major web browsers.
