pfSense

When attempting to add interfaces to IGMP Proxy or make any configuration changes, there is an error stating "There was a problem applying the changes. See the System Logs." This was reported in redmine https://redmine.pfsense.org/issues/13277

However, when testing today, I'm unable to get Multicast traffic to traverse from an upstream interface to a downstream interface.

With two interfaces LAN1 and LAN2, I started a UDP multicast stream from VLC on port 10000 on multicast address 224.0.0.1. I can see the traffic in a packet capture on the LAN1 interface as shown here:

22:26:12.993227 IP 172.21.92.146.45203 > 224.0.0.1.10000: UDP, length 1316
22:26:12.994176 IP 172.21.92.146.45203 > 224.0.0.1.10000: UDP, length 1316
22:26:14.019534 IP 172.21.92.146.45203 > 224.0.0.1.10000: UDP, length 1316

However, when running the same capture on the LAN2 interface, I see no packets being proxied across the subnets. The IGMP service starts, seems to be running, and other than the webConfigurator error it seems to throw no errors in the System logs, but it simply doesn't appear to be doing anything.
