📄 Description

Describe your changes

EBPF proxy between TURN (relay) and WireGuard to reduce number of used ports used by the NetBird agent.

Separate the wg configuration from the proxy logic
In case if eBPF type proxy has only one single proxy instance
In case if the eBPF is not supported fallback to the original proxy Implementation

Between the signature of eBPF type proxy and original proxy has
differences so this is why the factory structure exists

Issue ticket number and link

Checklist

Is it a bug fix
Is a typo/documentation fix
Is a feature enhancement
It is a refactor
Created tests that fail without the change (if possible)
Extended the README / documentation, if necessary
