Hello,
I would like to provide dvb streaming over multicast on my small mikrotik based network. My network looks like this:
streaming server — R1 — subnet 192.168.1.0/24 — R2 ---- subnet 192.168.2.0/24 ---- R3 ---- subnet 192.168.3.0 — R4 — wireless clients on subnet 10.0.0.0/8
I have set op vlc streamer on my streaming server and it runs very well. I am streaming few dvb-t streams. I can watch in web browser or vlc client over the http protocol. But I would like to use multicast udp stream because of bandwidth. Streaming server streams to multicast address 224.0.1.100 and ports from 5001 to 5005. Udp protocol is enabled in firewalls on my routers. I have configured multicast with igmp-proxy but it does not run. Then I tried set up multicast with routing pim but it does not run too. I used configuration written in mikrotik wiki. Wireless (and wired clients) can not watch dvb stream with vlc.
Please can I get some help to solve my big issue? Any help will be welcomed. 
And sorry for my English I am from Czech Republic. Thank you very much.
