What is the recommended way to configure Windows Server IPv6 DHCP on a 3 subnet network?
I had Windows Server 2012 DCs on 1 subnet and workstations on 2 other subnets. Until I watched your 70-410 DHCP episodes, our pfSense router that connected the 3 subnets was performing DHCP for both IPv4 and stateful IPv6 on all subnets. I now have DHCPv4 running on the Win Servers and pfsense relay agents configured for v4, but stateful DHCP v6 is still running from pfsense.
I'd like to have DHCPv6 running from the Win Servers as well, but after lots of searching I've come away with more questions than answers. If all clients are Windows 7, should I be using stateful or stateless DHCPv6? Why? Does DHCPv6 support relay agents for stateless? or isn't it needed? Should the pfsense router or the Windows Servers be doing the V6 DNS server address advertisements?
On a related note, I'm currently only running IPv6 internally, using a FDxx:: address range. When I set that up our ISPs didn't provide V6; I think they do now. I think I've read that V6 doesn't support NAT. Is that correct? How do I assign my servers static V6 addresses and give them Internet access over V6? I work at a small company with about 50 computers. We have 5 static IPv4 addresses from each of our 2 ISPs.
Any resources you could refer me to that clearly explain all of this would be greatly appreciated.
