IGMP - setup the right values
-
Good evening,
I'm now on PFSense 2.1 Rel. And want to config the igmp settings. The values for the two lans are simple. But I dont know where the multicast traffic comes from the wan side!? Setup is:
modem <- pfsense (dials up) <- networks
I just read a how to on http://pfsensesetup.com/igmp-proxy-configuration-in-pfsense/ but it says I should put a 0.0.0.0 and cdir as 0 in it. But I must chose a cdir between 1-32. I cant select 0?!
Please help me for the correct settings.
I also get the firewall log that 239.255.255.250:1900 is blocked. Could that be solved with the correct value?

Not mentioned in that guide is the firewall rule:
@https://doc.pfsense.org/index.php/IGMP_Proxy:
You also need a firewall rule on the downstream side (typically LAN) that matches/passes this traffic which has the advanced option checked to allow packets with IP Options.
This is different (I think) to the 239.255.255.250:1900 logs you are seeing. Those are probably a server on your LAN trying to announce itself via UPNP.
