Hi,
I've got a shiny new Sony TV with DLNA Support :)
My fileserver is located in a different subnet so it is not accessibly
by the TV.
The TV itself detects my netbook which is in the same subnet (and runs
Win7) as a DLNA source.
I've now tried to setup igmpproxy because I thought this might solve
my problem accessing my DLNA server in another subnet.
- Sony TV: 10.0.2.102 (fxp2)
- FreeBSD System running mediatomb: 10.0.0.21 (fxp0)
- Win7 System: 10.0.1.51 (fxp1)
- I did kldload ip_mroute on my router to get MROUTING
- I added "allow ip from any to any { via fxp0 or via fxp1 or via fxp2 }"
as a top rule to my ipfw configuration for testing.
- I installed igmpproxy, configuration:
quickleave
phyint fxp2 upstream ratelimit 0 threshold 1
altnet 10.0.2.0/24
phyint fxp0 downstream ratelimit 0 threshold 1
phyint fxp1 downstream ratelimit 0 threshold 1
phyint fxp3 disabled
phyint tun0 disabled
phyint lo0 disabled
phyint ipfw0 disabled
- I started igmpproxy
My TV still does not find any DLNA sources. I did a tcpdump on my
FreeBSD system and saw that some information was exchanged.

What am I missing to get it to work?
I also tried NATing the network where the TV is attached with divert/natd
but that also did not help.
Please keep me CCed
Greetings, Oliver
