Alternate Ports   The default port for SurfBouncer is 1194 -- the officially recognized port for the Open VPN application. Sometimes ISP's will block this port for various reasons. SurfBouncer will also run on other ports if 1194 is blocked. The configuration files below allow you to switch to port 443 or port 80 which will usually resolve the blockage. Windows: In order to change your port in Windows, download and run one of the following applets to switch your configuration automatically. The program will run almost instantly and make the changes behind the scenes.
