ICMPv6 iptables?

[mbze430]

I want to allow ICMPv6 traffic through the firewall, is there a way to add it so when I reboot the router it doesn't revert back?

Can you not use a user script? (https://github.com/RMerl/asuswrt-merlin/wiki/User-scripts)

Configure your rules on the IPv6 Firewall page.
