Just because the firewall is turned on does not mean that it is configured =
properly.  

Every version of Windows that ships with IPv6 support also ships with the F=
irewall configured in such a fashion that you may as well have it turned of=
f.  

This is especially true in Windows 8 and later where the firewall is reconf=
igured without your permission by Microsoft every time you install any upda=

absolutely no way to fix this other than to check, every single minute, tha=
t the firewall is still configured as you configured it, and not as Microso=
ft (and their NSA partners) choose to configure it.

All versions of Windows 8 and later whether using IPv4 or IPv6 are complete=
ly unsuitable for use on a network attached to the Internet by any means (w=
hether using NAT or not) that does not include an external (to Windows) -- =
ie, in network -- statefull firewall over which Windows, Microsoft, (and th=
eir NSA partners) have no automatic means of control.  If you allow UPnP co=
ntrol of the external statefull firewall from Windows version 8 or later, y=
ou may as well not bother having any firewall at all because it is not unde=
r your control.
