----------
The dhcpv6/ra/ndp uci parameters for the wan interface need to be set; they need to have similar values as the wan6 interface has :

config dhcp 'wan'
	option interface 'wan'
	option ignore '1'
        option dhcpv6 'relay'
        option ra 'relay'
	option ndp 'relay'
	option master '1'

config dhcp 'wan6'
	option dhcpv6 'relay'
	option ra 'relay'
	option ndp 'relay'
	option master '1'

Can you change the uci parameters accordingly and report back ?
