Description
Version 2.0.2-RELEASE (i386)
built on Fri Dec 7 16:30:38 EST 2012
FreeBSD 8.1-RELEASE-p13
"net.inet.igmp.default_version = 2" is set in System/Advanced/System Tunables. Right after reboot things are going well:
22:26:32.329851 IP 80.x.225.170 > 233.166.172.72: igmp v2 report 233.166.172.72
22:26:45.217090 IP 80.x.225.170 > 224.0.0.2: igmp leave 233.166.172.72
22:26:59.620307 IP 80.x.225.170 > 233.166.172.72: igmp v2 report 233.166.172.72
22:27:05.413067 IP 80.x.225.170 > 224.0.0.2: igmp leave 233.166.172.72
But suddenly for some reason the version raises up to 3:
22:28:07.153471 IP 80.x.225.170 > 224.0.0.22: igmp v3 report, 1 group record(s)

There is additional package installed - udpxy, which translates http requests into udp multicast (www.udpxy.com):
- ps ax|grep udpx
5337 ?? I 0:00.01 /usr/local/sbin/udpxy -a re0_vlan1 -m xl0_vlan442 -p 8888 -S -l /var/log/udpxy.log -B 2048K -c 2
udpxy authors state they do nothing with igmp version.

More information is needed here rather than this.
Some packet traces and system logs would be useful.
Debugging logs from igmproxy even better.

Here is an excerpt from the system.log for that small period:

80.x.225.169 is a default gateway. This might happen b/c I switched Internet feeding cable from one switch port to another. That took couple seconds. And this cable is not plugged into pfSense directly.

igmpproxy is off:

What packet traces would you like to have? There are a lot of traffic on xl0_vlan442.
Let me know if you need anything else.

Additional info: this morning I rebooted pfSense and after several hours tried to open the stream. igmp v3 appeared again:
# tcpdump -n -i xl0_vlan442 igmp tcpdump: verbose output suppressed, use -v or -vv for full protocol decode listening on xl0_vlan442, link-type EN10MB (Ethernet), capture size 96 bytes 12:00:54.443329 IP 80.x.225.170 > 224.0.0.22: igmp v3 report, 1 group record(s) 12:00:54.843280 IP 80.x.225.170 > 224.0.0.22: igmp v3 report, 1 group record(s) 12:00:59.468331 IP 80.x.225.170 > 224.0.0.22: igmp v3 report, 1 group record(s) # sysctl -a|grep igmp net.inet.igmp.gsrdelay: 10 net.inet.igmp.default_version: 2
So, it seems to be using igmp v2 just a short time after reboot.

Run into same issue and found some kind of more detailed description.
Reason seems to be that freebsd is very strict on what it is expecting, and there is some mess with the code.
Providers, on the other side, are not capable of sending all messages strict to rfc, reasons vary. While it's fine with windows and linux, freebsd breaks robustness principle here.

- Status changed from New to Resolved
the linked thread in Vasyl's comment has the solution on 8.1, and 10.x doesn't appear to have same issue.
