The default port for SurfBouncer is 1194 -- the officially recognized port for the Open VPN application. This will work in most cases, allowing you to surf securely and unblock the internet. Sometimes, ISPs will block this port for various reasons. In such instances, SurfBouncer can also run on other ports. The configuration files below allow you to switch to port 80, 443, 4500 or 5632 -- which will usually resolve the blockage.
In order to change your port in Windows, download the configuration file for the port you wish to change to (right click and "save as"). Place it in the OpenVPN config directory.
Port 80
Port 443
Port 4500
Port 5632

In some cases, the Mac will save the file with a '.txt' extension. Remove the .txt to use the file. The file name should end with '.ovpn'. After copying the files, exit Tunnelblick and restart it. It may ask you for your Mac password before allowing the VPN login to appear.
If these changes do not resolve the issue, then you may need to switch to a TCP server. For more information, see the section on the troubleshooting page that reads "TLS key negotiation failed to occur within 60 seconds".
