Original Pull Request: https://github.com/netbirdio/netbird/pull/826

State: closed
Merged: Yes

Describe your changes

This is initial changes to support shared port between stun (ICE agent) and
the kernel Wireguard

Implement single port mode for execution with kernel Wireguard interfaces using a raw socket listener.

BPF filters ensure that only stun packets hit the raw socket

Removed a lot of the proxy logic and direct mode exchange

now we are doing an extra hole punch to the remote wireguard port for best-effort cases and support to old client's direct mode.

Checklist
