Minidlna No UDP Multicast outside a jail @ Freenas 9.2.1.3

[JeckJeck]

Dear Forum,
I am desperate:
I have a new Freenas 9.2.1.3 up and running. I am trying to run a minidlna in a jail...here the status

• minidlna installed inside a jail via automatic plugin installation.
• minidlna is up and running, I can reach its website @ Port 8200 from any PC in the LAN, watching the media database being built up
• I can ping the jail from any PC in the LAN. It is also visible with its IP Address in the home router
• Same applies for the FreeNas Host: can be ping'ed and is visible from everywhere inside the LAN; SMB CIFS also works perfect

Problem: The minidlna media content server cannot be discovered from any machine inside the LAN

Test:

• traceroute on the jail: Multicast Traffic for SSDP visibile (used to announce the DLNA Server) - OK!
• traceroute on the host: Multicast Traffic from the jail is also visible on the freenas host
• wireshark on a PC: No (!) SSDP multicasts from the jail are visible in the LAN, tested on a win7 PC in the LAN
• However crosscheck: Wireshark proofes that SSDP multicasts are broadcasted in my LAN, tested it with some other dlna media server

What could be the problem???

Is there a firewall in the network?

The only firewall in the network is in the WAN Router connecting me to my ISP. For testing resons I have switched it off on all hosts.
In addition to this: As written earlier my network can handle SSDP Multicasts as I can see them in wireshark if sent by some other DLNA server.

Any other ideas?

Has this ever been solved? I have a similar issue using UPNP/DLNA in a jail: no multicast getting in&out using VIMAGE, no NAT, the application cannot even bind to multicast addresses..
