dhcpv6 blocked by firewall

[bipiq]

My dhcpv6 seems being blocked by firewall. Every time I try to connect to the network (I mean on linux `nmcli connection up myconnection0`) the log live view show me this:

If I'm not mistaken the ipv6 address ff02::16 should be something relevant to dhcpv6, and therefore should not be blocked.
I also noticed there is some default floating rules:

However these rules' protocol is ipv6-icmp other than icmp, which was blocked and logged.
What should I do to solve this?

I'm pretty sure that DHCPv6 is ff02::2 (all routers).

Since the last 2 updates and additional automatic rules added I found similar issues. I'm posting with screenshots to show my work.  The floating I added the fe80::/10 to ff02::/16 due to Auto Rule wasn't working for me.  The LAN I had to clone and delete the original Defaults to get them to work again.  The WAN I added "Allow All ICMP Inbound", Disabled BOGONS on WAN Interface (because AUTO Rule  was blocking my WAN GW address fe80::yada:yada from my ISP to LAN ff02::1 Multicast address, then manually enter the bogons rules.  Hope this will help you.  Been a learning experience for me...

BTW...  Below is a filter log showing before (bogons enabled) and after (bogons disabled) in reference to WAN Interface and auto generated rules for bogons and bogons6.

Last note to add... If using a bridge for multiple lan ports, I would enable "link-local address"
