Stream is only multicast in 2.2

Hello,
I installed the plugin today and there seems to be bug regarding the new multicast feature.

The latest release outputs multicast only, disabling enable Multicast-Checkbox is ignored. I noticed this because just clients in my LAN were able to consume the stream. Clients connected via VPN couldnt access. I attached two TCP Dumps I got on the VPN client (2.1 success, 2.2 failed):

TCP Dump using release 2.1, without multicast-feature:

Think this is the same problem #105
