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@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
