[Bloat] Multicast forwarding

[Kail]

Hi all,

I'm trying to enable DLNA across wifi and wired on 3.10.

PIM is already there is seems to be configured correctly (but for RP
address, but should not need this).

I added a rule on mangle PREROUTING for incresing the TTL by one for
224.../4

I've 3 devices that serves as media servers but only those on sw00 see each
others.

root at cerowrt:~# ip mroute show
(172.30.42.72, 239.255.255.250)  Iif: sw00       Oifs: se00 sw10
(172.30.42.21, 239.255.255.250)  Iif: se00       Oifs: sw10 sw00
(172.30.42.73, 239.255.255.250)  Iif: sw00       Oifs: se00 sw10

Following hints from the guide [1] I tried pinging 225.1.2.3 from
172.30.42.21. This resulted in
(172.30.42.21, 225.1.2.3)        Iif: unresolved

and 'pimd -r' shows no sign of this group.

No icmp or igmp packets are sent on sw+ for this multicast pings.

Do you have any suggestion on what and where to look. I don't like the idea
of bridging the internal lans.

Thanks,
Kail
