windows server bridge mode fails

[bajnokpityu]

Hello, I have a problem.
I use dual lan ports (intel dual lan card).
One of the port is directly goes to Lumin, the other port goes to the main switch.

Under debian linux minimserver it goes okay with bridge mode, Lumin can stream music, but under Windows (8.1 or server 2012 r2) it cannot stream. I tried from a computer with foobar upnp client, it started, but musis is listenable.

This is a minimserver problem, or windows problem?
