Hi, Im new to NB, so forgive me if I overlooked something.

My Setup:

Online VM with all self-hosted netbird containers running as per installation instructions
Local Windows machine with NB client (windows.netbird.domain.net)
Local Linux machine running NB client in docker (with HOST networking) (linux.netbird.domain.net)

Local Windows and Linux machines are the on the same subnet.
Peer connection from Windows to Linux machine works but is always relayed via the Online VM and I dont understand why.

Output of netbird on Windows:

netbird status -d

Peers detail:
linux.netbird.domain.net:
