Input validation error when saving IGMP Proxy settings
100%
Description
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.

Can this be reproduced on 23.05? Are you sure this isn't the same problem as #13929 ?

Note that that's mostly only a cosmetic problem. It does actually start igmpproxy.
I'm investigating another issue, which I suspect to be limited to virtio interfaces, and possibly only those on bhyve, but as I said: I'm still investigating.

The virtio issue did turn out to be a virtio problem. It doesn't allow IFF_ALLMULTI to be set (on systems where the host doesn't announce VIRTIO_NET_F_CTRL_RX support), so igmpproxy couldn't start.
https://reviews.freebsd.org/D41356 will fix that.

Tested on Aug 18th builds of Plus 23.09. No errors are present when saving IGMP Proxy anymore. This can be closed as resolved.
