Igmp problems

Hello all,

ive been the last days figthing with my new RB433GL trying to get DLNA to work from
ethernet port to wlan interface. My config is pretty simple, and i decided to remove
all the firewall rules so they dont interfer with the multicast/dlna negotiations.

My net is really simple → eth1 (172.16.0.0/24) - [ RB433GL] - wlan2 (172.18.0.0/24)

I have tried many combinatios of configurations:

  • igmp-proxy → Followed the upstream scheme explain on the mikrotik igmp-proxy doc
  • pim
  • upnp - > activated on both interfaces as internal. But didnt see any dummy rule
    on the fw (Is that a sign of something wrong ?)


    Even creating a bridge with eth1 and wlan2 and assigning the same ip subnet to both
    (172.16.0.0/24) the communuications fail to work. This is not the scenario i prefer
    but i had to give it a try because of my deseperation.

I have followed this tutorial that reflects my same scenario.

http://wiki.mikrotik.com/wiki/Manual:Routing/IGMP-Proxy

I really need your help pleeeasseee .-(, i even tried the same configs on v6.1 but didnt
work. Ill post some traffic captures and igmp status later ..

Thanks
Javi

I decided to stay with v6.1 but do a factory reset, so nothing apart from eth1 and eth2 was configured.
Then i setted up the upnp on eth1 and eth2, and activated it.

Then i configured igmp-proxy and succesfully saw mfc entrys, but traffic between tv and pc is just
not working. Somehitn gs

Then why am i seeing this ?

Seems to me weird that the proxy didnt recognised the direct and configured ipnet.
Should i see somekind of dummy rule on the firewall because of the Upnp ?

Any ideas ?

Regards

Heres a screenshot of a capture on the mikrotik eth2 interface, any help please? Should I really add an alternate address?
