About disabling IGMP Snooping..

[lyapounov]

A genuine question: it says in minimserver documentation that disabling IGMP snooping can solve issues.

My question is: disabling where ?

My architecture (only the part focused on multimedia):
I have a main router, ASUS RT-AX68U Pro
To this router is connected a switch Zyxel GS1200-5 to which my TV and my Oppo are connected
To this switch I cascaded a Buffalo BS-GS2008 (BTW almost same HW as Melco switch at 10% the price ;-)
To this Buffalo are connected only my synology and my Linn Klimax

So I can disable IGMP snooping on the Buffalo, on the Zyxel and on the router.

Should I disable everywhere, or only the Buffalo ?

Thx !
