Just for the sake of contributing, I found ppl that had such problems as i had, so i'll just share my findings and propose a change/add to the Wiki IPTV_-_blocking_multicast_on_WIFI page.

So, to the point.
I have a Broadcom based Belkin router with latest DD-WRT Build installed and bridged to a Thomson TG784 which is the main router, making the connection to my dsl and IPTV provider. So, to connect my STB to the DD-WRT router and get multicast, but block it on wireless so it wouldnt get flooded, i used the Wiki tutorial. Section "Block Multicast via Firewall".
Prize: Rendered my network shares unaccessible via wireless (only on DD-WRT router) while still accessible via wireless on the main Thomson router and on both routers via ethernet.

Conclusion:

I fuzzled with the instructed ebtables rules and got it all working perfectly using the following:

Quote:
insmod ebtables
insmod ebtable_filter
insmod ebt_pkttype
insmod ebt_log
ebtables -A FORWARD -o "eth1" --pkttype-type multicast -j DROP --log
ebtables -A OUTPUT -o "eth1" --pkttype-type multicast -j DROP --log


So, add the extra modules ebt_pkttype and ebt_log (which is only necessary if you need logging, and remove the "-d Multicast" rules which were the ones blocking network share.
Hope i help somebody out.
Cheers!

I have had the same problem, but I had to separate the lan and wlan, because I don't know how to use iptables.

Can you explain how I can do it by using iptables, because right now I can't connect from my wlan to the lan.(so no control of my MediaCenter from the phone Sad

I'm a total newbie using the Command shell on my router.
It's a WNDR3700 with DD-WRT v24-sp2 (12/24/10) std

Hope you guys can help me.

/K.
