Multicast

DaddyGo

es the diagram is correct,

I used to deal with MS load balancer (especially multicast), long time ago...
(we always use a hardware base load balancer, HA proxy )

but I am interested in this topic...

no this will not work under pfSense.... (100%)
bring the theme under linux...

Hi
I have also come to the same conclusion that multicast and Pfsense is not the way to go, and start to setup HAProxy.

But thanks for you suggestions.

it took me a long time to understand what do you mean by original post, I apologize
just the way, it works...HA proxy

+++edit:
@hsv "but I only have 4 WAN, but I guess the problem will be the same."

this does not matter

@daddygo do you have any tutorial on how I can configure Multicast? I have CISCO SG300 with 2 Vlan
thanks

@n3xus_x3 Note that

if source and destination is in the same vlan/subnet, it simply works. In case you have a bigger subnet and advanced switches you could/should use IGMP Snooping to prevent unnecessary traffic
is your multicast source is in a different vlan/subnet, than:

you need an application which forward the multicast messages between the involved vlan's. That is also where the problem is, since neither the actual IMGP-proxy nor the Netgate provided PIMD-version2 works!
assuming you manage to get a working multicast deamon, you should configure pfSense to pass the related unicast traffic between the involved VLAN's

Personally I have multicast working between VLAN's based on an upcomming beta PIMD-version which I did compile myself (Trogobit (https://github.com/troglobit/pimd). So not so easy at all. I hope there will be a released and Netgate supported version in the future.

For info and in case you have the knowledge and are very brave, sources are on Trogobit (https://github.com/troglobit/pimd).

Troglobit is working on an improved PIMD-version at the moment. It is beta and not supported by Netgate or Trogobit (not for FreeBSD), however in opposite to the actual pfSence IMGP-proxy and PIMD-version, it does work!
To make it work you need some courage, knowledge, pfSence 2.5 and a FreeBSD development machine. If that is present, you can download the pimd source from github compile it and install it on your pfSense system from the commandline.
To make it even more complex, .... the pfSense pimd application has two components beeing: the pfSense PIMD control/GUI- application and PIMD it-self. You also have to make some small changes to that pfSense PIMD control/GUI.
Because it is still early beta!! and I do want to interfere with Troglobit or Netgate, I am >not< going to release my personal pimd-package in this stage. So for now you are on own.

My advice: unless someone has an alternative solution, I can only advice to wait or to place source and destination in the same vlan.

@louis2 Hi Louis2
thank you for the explanation . sorry but i'm slightly confused , I explain what I want to do

My pfsense configuration

Vlan50 192.168.50.0/24 (WiFi devices)
Vlan60 192.168.60.0/24 (CCTV)
LAN 192.168.1.0/24 ( IPTV , Emby)
LAN2 192.168.10.0/24 (wired systems)
DMZ 10.10.50.0/24

Currently only some devices that are in VLAN50 , have access to some IP addresses that are on the network VLAN60 and LAN

My question is , do I need to configure pFsense and the switch (Cisco SG300) for Multicast to work properly? i want multicast between VLAN50 , VLAN60 , LAN .

I apologize if I have been confused
Thanks
Mark

@n3xus_x3

Since source and destination are in different VLAN's/subnets, without additional measures the communication will never work!

The source generates "hello I am a source" messages and distribute those in its own subnet/vlan. Those messages will never reach the client in the other subnet/vlan. So the client will not be aware of the source.

To change that you need an application which bridge the vlan's in regard to the multicast messages. And at this moment in time there is no working app available for pfSence to provide that function.

The only option I am aware of is the beta pimd version. But I would not advice to try that in your case.

Sincerely,

Louis

@louis2
You have been very clear, Thanks for your help. I will wait for the Trogobit project to be ready

cheers

Hi,

can also be solved on SG300, but MULTICAST handles it a little differently on it, I suggest the SG350 series it is a little more painless

BTW:
otherwise what are you using multicast for

n3xus_x3

@daddygo
Hello , I use multicast for IPTV reception, and for Emby Server for local and remote transmission (VPN) of video content .
i try to find some tutorials for my SG300

@n3xus_x3 said in Multicast:

I use multicast for IPTV reception

there are still 2 - 3 pieces of SG300-10 in our (AoIP system + multicast) system,... yet

how can I help?
describe it exactly

BTW:
IPTV in this regard, is deadly, ISP dependent...
