I don't want to sound snarky either it's a genuine question, but why get a 
router with firewall? I'm not ipv6 yet but I am trying to get there - one 
of my fundamental design parameters I have been working to on my network is 
that every device handles it's own firewalling.

Im still trying to get my head around why ISP's are implementing IPv6 
firewalls and how that can work in practice.

Is the theory that everything is some sort of UPnP equivalent capable?

My current IPv4 ISP provider doesn't even do a full firewall, they block 
SMTP port 25 and a couple of others with an opt in / out option but that is it.

I thought it was simple - once you went IPv6 you were world accessible so 
your individual devices better be ready. If your device can't handle Ipv6 
world access then only option is to put it behind an IPv6 to IPv4 gateway 
and NAT pseudo protection. Is this wrong?
