Hi @giantdave 

Thanks for your post.

If you are planning to create blocking  IPv6 communication rule, you should select "IPv6 protocol" in "Add rule" like as attached screenshot.

Protocol 41 is IPv6 encapsulation over IPv4; ref https://simple.wikipedia.org/wiki/Protocol_41.

In a Firewall rule, set the Transport Protocol to IPv6 encapsulation in IPv4.
