Multicast routing / IGMP snooping

[Patron85]

Dear all, i wanted to improve my multicast traffic enabling IGMP snooping and multicast routing. I am using a Fortigate 40F (7.2.10) together with a Fortiswitch 108F and FortiAP 231G. Before, multicast between my VLANS (ports are on NAC mode) worked perfectly, but now I am lost and I do not know what I am doing wrong...

Here some information out of my CLI:

FortiGate40F (settings) # show
config system settings
set multicast-ttl-notchange enable
set gui-multicast-policy enable
set gui-dos-policy enable
set gui-local-in-policy enable
set gui-dynamic-routing enable
set gui-advanced-wireless-features enable
set gui-email-collection enable
set gui-multiple-interface-policy enable

FortiGate40F # get switch-controller igmp-snooping

flood-unknown-multicast: disable
