However, in some cases, when ports are closed or used by other applications, it is necessary to manually specify the port numbers available for incoming connections to Skype. The way to do this must be consulted in the management manuals of the respective applications.Īs we can see, in most cases, the configuration of the ports does not require user intervention, since these parameters are automatically detected by Skype. This article explains the 7 default options in sshdconfig file that you should change.

In this case, you should uncheck the above option, but better yet, redirect the conflicting programs to other ports. OpenSSH options are controlled through the /etc/ssh/sshdconfig file. It can be in those rare situations where other programs not only occupy port 80 or 443, but also start to conflict with Skype, which can lead to its inoperability.

This option is enabled by default.īut, there are times when it must be disabled. If the port is available, it can be used for incoming Skype connections.Īlso, make sure there is a check mark in the settings for 'Ports 80 and 443 should be used for additional incoming connections.' This will ensure that even if the primary port is temporarily unavailable, the application will still work. For Skype to work correctly, the following ports need to be open in your firewall: 443/TCP 3478-3481/UDP 50000-60000/UDP For the best possible call quality experience, these ports are needed too: 1000-10000/TCP 50000-65000/TCP 16000-26000/TCP Make sure your firewall or security software is configured correctly with these ports. (So for example you can have one Windows process listening on port 80 as Skype sometimes does by default, or one WSL process listening on port 80, but not both. From Windows CMD, you can issue netstat -an to see what ports are open, and (with a bit of luck) which have something listening. This can be done in special web resources, like 2ip.ru. WSL (Bash.exe) shares the IP address (and port availability) with Windows 10. To do this, simply enter any other number in the window with the port number and then click the 'Save' button at the bottom of the window.īut, it is necessary to check beforehand, if the chosen port is open. If the port selected automatically by the program is closed, or is frequently used by other applications, it must be changed manually.
