I tried disabling IGMP snooping and everything stopped working!! Kazoo/Kinsky couldn't see either the QNAP of MacMini servers - nor could it see any of my Linn streamers!

The switch is running V3 IGMP - I have no idea how to roll that back....

Any more advice/thoughts?

P-M

Are the IGMP queries being generated by the router or the switch? If they are being generated by the switch, there is a configuration option for my SG300 to select either IGMP v2 or IGMP v3. I presume you have the same option for your SG200.

For details of the problem that I experienced when using IGMP v3 with a Mac, see this post.

Thanks

When I accessed the IGMP page on the Switch earlier I am absolutely sure it said V3 - however on revisiting it says V2! I've tried to add a screenshot but not sure how to on the forum!

The IGMP Snooping settings I appear to have access to are (current settings in brackets):

Query Robustness (2)
Query Interval (125)
Query Max Response Interval (10)
Last Member Query Counter (Use default)
Last Member Query Interval (100)
Immediate leave (Enabled)

Can't see any field for selection of version number.

I assume that this is all coming from my switch as there is no reference whatsoever to IGMP in any of the config menus of the router.

Thanks

PS - Not sure if relevant but on the IGMP/MLD IP Multicast Group Table the port where the QNAP is connected features multiple times. However the port the MacMini is on does not appear anywhere.
