Skype supports connection to its service through a proxy server to, for example, bypass restrictions on Skype traffic on your network or to hide your Internet protocol address from contacts. Configure Skype's proxy settings from the Connection Options window, which you can access by opening the Tools menu and selecting Options.
Launch the desktop version of the Skype 11 client under Windows 8.1 or 7. Open the Tools menu and select Options.
Select Advanced from the sidebar to reveal a new set of subcategories.
Click Connection to access Skype's proxy settings.
Select HTTP5 or SOCKS5 from the drop-down menu if Skype fails to detect your proxy settings. By default, Skype attempts to automatically detect the correct settings. However, if Skype is unable to connect to your server, you may have to enter your proxy details manually. To do so, select your proxy server type from the drop-down menu and enter its host name and port.
Click Enable Proxy Authentication and enter your credentials if your proxy server does not allow anonymous connections.
Confirm your settings by clicking Save. Close Skype by opening the Skype menu and selecting Close. Restart the program to connect using your new proxy settings.
