There were no firewall changes for quite a while really and IPv6 
configuration hasn't been touched for quite a while either and if you 
have ruled out the igmp_snooping as a source of error then thats a bit 

OpenWrt switched from using kernel-mode IPv6 RA handling (SLAAC) to 
handling RAs in userspace some time after the AA release that means you 
need to have a proto=dhcpv6 interface section in /etc/config/network for 
using IPv6 SLAAC (in forwarding mode) as is done in the default 
configuration of OpenWrt.

Alternatively you might set the sysctl value to accept RAs in forwarding 
mode but this is greatly discouraged and might cause some issues with 
other parts of OpenWrt.
