Difference between igmp_snooping on switch and interface section

Installing and Using OpenWrt Network and Wireless Configuration

I read this topic today:

You wrote disabling IGMP snooping makes igmpproxy unnecessary. Now I'm thinking my igmpproxy config isn't correct.

Now I changed my igmpproxy config like in the wiki:

config igmpproxy
        option quickleave 1
#       option verbose [0-3](none, minimal[default], more, maximum)

config phyint
        option network wan
        option zone wan
        option direction upstream
        list altnet 0.0.0.0/0

config phyint
        option network lan
        option zone lan
        option direction downstream

My network config:

config interface 'loopback'
        option ifname 'lo'
        option proto 'static'
        option ipaddr '127.0.0.1'
        option netmask '255.0.0.0'

config globals 'globals'
        option ula_prefix 'fdbc:33fb:8f21::/48'

config interface 'lan'
        option type 'bridge'
        option igmp_snooping '1'
        option ifname 'eth1.1'
        option proto 'static'
        option ipaddr '192.168.1.1'
        option netmask '255.255.255.0'
        option ip6assign '60'

config interface 'wan'
        option ifname 'eth0.7'
        option proto 'pppoe'
        option password 'xxx'
        option username 'xxx@t-online.de'
        option ipv6 'auto'

config interface 'wan6'
        option ifname 'eth0.7'
        option proto 'dhcpv6'

config switch
        option name 'switch0'
        option reset '1'
        option enable_vlan '1'
        option igmp_snooping '1'
        option igmp_v3 '1'

config switch_vlan
        option device 'switch0'
        option vlan '1'
        option vid '1'
        option ports '1 2 3 4 5 6t'

config switch_vlan
        option device 'switch0'
        option vlan '7'
        option vid '7'
        option ports '0t 5t'

And in the firewall config I added the input rules:

config rule
        option target 'ACCEPT'
        option family 'ipv4'
        option proto 'udp'
        option dest_ip '224.0.0.0/4'
        option name 'iptv'
        option src 'wan'

config rule
        option target 'ACCEPT'
        option src 'wan'
        option name 'Allow-UPD-IPTV'
        option family 'ipv4'
        option proto 'udp'

With these settings I can see via tcpdump only the routers IP-address in the packets (192.168.1.1). Of course IPTV isn't working. When I disable IGMP snooping network is flooded but IPTV works and I see all IPs via tcpdump.

That makes me think my igmpproxy isn't working properly?
