Multicast, who accessed??

raji_toor — Mon, 14 Jun 2021 16:13:25 GMT

I have tested multicast to be working and is configured as in this diagram. In the logs I see traffic from SERVER zone to Multicast zone. But there is no log on INTERNAL client that accessed the multicast stream.

Hello,

Should there be? The tcp session will show the traffic from where it was initiated.

@OtakarKlier In the VLC streaming test no session was created from client to MCAST server.

Its the server going from server zone to multicast zone creating session.

So essentially in this scenario there is no easy way to control access for multicast with policies and only option is to restrict in the VR. Am I right?

Hello,

Well the policies can still be used to limit the destinations IP's/Subnets you want the traffic to go to so they are still relevant.

Hope that helps.

@OtakarKlier As per the network explained previously, I see this in logs. I cannot think of how you are suggesting i can control with policies. There is no traffic directly to/from mcast server(172.20.0.46) to/from client(10.x.x.x) as this will be the unicast traffic and not multicast. Only traffic is see here is going from mcast server to the multicast address. I have no logs of client to/from accessing this multicast address(239.255.100.2) although client is able to view the muticast stream.

Hello,

What zone are the clients that you would like to see the traffic to in? If the clients are in a different zone or subnet, you can either set a deny to a destination subnet or zone.
