Multicast

RouterOS Forwarding Protocols
1

I tried to create a test multicast network. Example is below. When I start an RTP stream on the VLC server I can pick it up localy. So that is running The stream uses an address of 224.0.1.1. However the client won’t connect to the stream on the server. When I setup a simple bridge with two ports in it, the stream will run, obviously. There is something with the layer 3 config, I think…

I read the Wiki on the site, viewed MUM demo’s and so on. Is there anyone who can help me to get a bit further.

Im missing the forward rule in the firewall, I dont know the command out of my head but it should be

Firewall → add rule → forward → DST-Adress = 224.0.0.0/4 → -> in interface / out interface → action accept or passthrough..

There are no firewall rules what so ever. The only config on the routers is that what you see.

But thank you vert much for thinking about it

There’s a chance that you have packets with TTL=1. If you have them, you can increase TTL using mangle.

I recall it was explicitly mentioned for VLC when tried to configure my setup.

Check this example as well, it has nearly yours case.

Thanks, I will test the solitions in a day or two and let know if it is resolved.

Thanks TTL it is!!!

Is it not possible to configure the TTL in VLC?

From what I have read, no. There is something in VLC that is preventing that.
