Describe the new feature you'd like
Reverse the connection establisment so the server connects to the client. Alternatively skipping this part completely and broadsast the udp so the client can listen to it without making any negotiation.

Describe the reason why you want to add the feature
The windows cannot open incoming client request due to the policy rules.

Describe how to implement the feature if you can
Two options:

1. Reverse the initial connection negotiation, so the server periodically sends requests to the client, or
2. Simply allow skipping that part and always stream the udp, so the client can listen to it without initial negotiation.

Additional context
Depend on above options:

1. A checkbutton in both server/client app that changes the logic of the negotiation direction. or
2. A checkbutton in both server/client app to ignore the initial negotiation step, so server always streams the udp, client simply plays if that udp comes in.
