Config igmpproxy to allow multicast udp from WAN to LAN

Installing and Using OpenWrt Network and Wireless Configuration
21

I now tried 224.1.1.1:1234
still not working. when opening the stream i can see IGMPv2 in wireshark but the stream won't start.

22

Please use valid multicast IP addresses!

  • and put quickleave back to the default value if you have not done so
23

so which should i use ? do I need to enable igmp snooping on my router ?
quickleave has been set to 1

24

A valid IP. I don't know what your multicast server is doing - I assume streaming video. An IP from the adhoc block should work.

No one has mentioned it yet except you. We're suggesting you get igmpproxy setup first.; but you seem distracted with snooping and firewalls.

25

all I have done was installing igmpproxy and replaced the lines in /etc/config/igmpproxy with those posted above. So is it correctly setup now ?

26

Is your multicast working!?!?

27

no of course its not working. what do you mean ?

28

Again, you refused to answer me. We cant help if you keep making guesses - or forcing us to make them.

  • If not explain clearly what happened.
  • Also, you never said if you fixed the wrong multicast IP
  • What software are you using to run a multicast server
  • Explain its setup

If you're using VLC, I'll setup and test your exact config myself.

I'm using VLC. Select videofile, select stream UDP Legacy 233.252.0.0 onport 1234.
Opening with VLC udp://@233.252.0.0:1234
I used an AdHoc Block 3 Address
My Setup is just as I said. Just a PC on WAN and another PC on LAN. No Internet Connection.

This isn't multicast - it's unicast. Why don't you setup multicast if you want the OpenWrt community to assist with igmpproxy???

From: https://wiki.videolan.org/Documentation:Streaming_HowTo/Easy_Streaming/

  • UDP : Stream in unicast by providing an address in the 0.0.0.0 - 223.255.255.255 range or in multicast by providing an address in the 224.0.0.0 - 239.255.255.255 range. It is also possible to stream to IPv6 addresses. Note: This will only work with the TS encapsulation method.

Not sure this is valid, can the last two octets be 0? try 233.252.0.1

Sorry thats completely new to me . So I need to use RTP ? because I tried multicasting in bridged mode and it worked with UDP.

33

If you were in bridge mode, you weren't multicasting.

@mickey84, I really think you need to review the VLC documentation on setting up a multicast stream.

  • I don't feel comfortable assisting with the non-OpenWrt portions of your setup (in fact, it's off topic)
  • It's also clear you have not setup your multicast stream correctly yet, so there's nothing for me to setup and test using igmpproxy at this time

See:

34

I tried exactly like in th video. I also tried different addresses and ports. It's not working.

35

I also found lot of tutorials that used UDP legacy for multicasting. I also did everything exactly I was told to.

36

Did you open the firewall on the VLC machine?

(Also, I'm not sure why you want to follow a tutorial that's contrary to VLC's
documentation; hope that works for you.)

37

You mean allow VLC in windows 10 ? Yes I did that

38

also disabled firewall on both computers. nothing works. I really don't know . won't come any further without help.

39

Plug the source into a switch and plug a second computer into the switch, run Wireshark on second computer, does source send multicast packets? If so it's not your source that's the problem.
