Which ports need to be open to use Skype for Windows desktop?

To work correctly, Skype requires unrestricted outgoing TCP access to:


  • All destination ports above 1024 (recommended)


  • Ports 80 and 443 

If your firewall restricts access to both of these, you will need to update your firewall settings before you can use Skype.

When you install Skype, a port above 1024 is chosen at random as the port for incoming connections. You can configure Skype to use a different port for incoming connections if you wish, but if you do, you must open the alternative port manually. 

If the port chosen for incoming connections becomes unavailable, by default ports 80 and 443 will be used as alternatives. If another application (such as Apache HTTP server or IIS) uses these ports, you can either configure the application to use other ports, or you can configure Skype to not use these ports.

To configure the ports that Skype uses for incoming connections:

  1. In Skype, from the menu bar, click Tools Options.
  2. Under Advanced, click Connection.

  3. Enter the port that you want Skype to use for incoming connections.
  4. Choose whether to use port 80 and 443 as alternatives for incoming connections.

    If another application (such as Apache HTTP Server or IIS) uses these ports, Skype may not function correctly. Either uncheck this box, or configure the other application to use different ports.

  5. Click Save.
