Mwan3 and ipv6 firewall does not work

Installing and Using OpenWrt

I have two wan interfaces, wan (ipv4) and wanb (ipv4/ipv6). the policy works only for ipv4 with priority to wanb. The ipv6 rules are disabled. I have a forward firewall rule for ipv6/udp/port to an internal PD global ipv6 host (wiregaurd). this rule does not work with mwan3 (when service is disabled it works). the ipv6 does not have NAT. I understand there is a limitation with ipv6 but I can't make it work without failover/load balance. I'm ok that ipv6 will fail.

managed to solve this, to bypass ipv6 need to add this, when

config rule 'default_ipv6'
        option family 'ipv6'
        option proto 'all'
        option sticky '1'
        option use_policy 'wanb_only'
        option src_ip '::/0'
        option dest_ip '::/0'


config policy 'wanb_only'
        list use_member 'wanb_m1_w2'
        list use_member 'wanb6_m1_w2'
        option last_resort 'default'

this is not optimal but at least I have ipv6 working and ipv4 with failover
