📄 Description

Hi,
In the current implementation of the UDP port assignment, the compiled binary triggers Windows Firewall whenever it requests a particular port directly.
However, should the ephemeral port request be relayed to the OS directly, everything still works, is handled automatically and no firewall is triggered.
