How can I open a port (or more ports) e. g. 6666 in Edge for ever? Does there exist a similar comfortable way as it does in Firefox? There it is possible to do that for more than one ports in a very easy way. Also in Google Chrome exists an easy way for doing that.

Hi, I'm Elise, and I'd be happy to help with your issue.
You need to run Edge from the command prompt such as this:
msedge.exe --explicitly-allowed-ports=6666 http://example.com:6666
Please let me know if you need any further assistance.
Kind Regards,
Elise
