Yes, I know, I'm just wondering why you're using TCP at all for
synchronizing. Its not for traffic from the Internet I assume
since the node it ends up on is unknown to the outside anyways.

No, that's not the syncronizing traffic, but the "normal" TCP traffic to be filtered by the firewalls, which have got multicast MAC addresses on their interfaces.

Multicast traffic is accepted for forwarding just fine, its just
local TCP delivery thats refusing it. So it can't be forwarded
traffic.
