IPv6 security & OPNsense

[phoenix]

While I was doing some searching on the internet about IPv6 I came across this article:

https://www.secfu.net/2017/04/16/opnsense-as-an-ipv6-firewall-testing-ipv6-security-devices-part-1/

Not understanding the technical details of that article I was wondering if that is of any concern to OPNsense users?

Too technical for me.  However, for IPV4 most people filter traffic based on much fewer parameters.  Seems like it to me anyway,    Seems like most people filter on originating IP, destination IP and a few other things like if the packet is fragmented or out of state. 

Specifically, what sort of filtering for IPV6 is opnsense missing that it CAN do for IPV4? 

That would be meaningful for me.
