ipv6 pinhole for the Xbox ports

Port forward must bring IPv6 if you have that enabled ??

Port forward has nothing to do whether an IPv6 address are being leased to a host, or not.

Xbox One uses different behaviors to benefit and to make peer to peer (P2P) more simple than the Xbox 360. The main benefits is IPv6 with IPsec and Teredo (which is a transition mechanism that gives full IPv6 connectivity for IPv4 connectivity that do not
have a native connection to an IPv6 network).

Xbox One will mainly use Teredo implementation (which is sensitive to NAT behavior) and it prefer port 3074 for P2P traffic which is the same port for Xbox 360 traffic. Does this mean that your current setup will break UDP PortMappings (Port Forwarding, QoS)
for Xbox One! No it doesn't!. If there is a port competition problems, Xbox One has a fall-back-mechanism to use other ports as well if 3074 is not available.

192.168.1.254 or 192.168.1.1 on ur computer login username should be admin and password should be key on ur internet modem box once your in go to advanced settings and look for either DMZ mode and enable or UPNP those should fix ur nat settings to open and
if not disable the firewall security on that same settings page and if that does not help u will need to open ports/pinholes the xbox ports could be found here

Hi Big Lad 4 That,

IPv6 is a standard which has been developed so that port forwarding is no longer required. You do not need to forward any ports to get IPv6 functioning on your home network.

Thanks,

Xbox One users Let me make this simple. Forward port 3544 to 3074.

Reason:

Microsoft uses IPv6 so it first encapsulates your inbound traffic that eventually should go to port 3074 (Xbox Live) using Teredo:

en.wikipedia.org/.../Teredo_tunneling

That's why port 3544 needs to be forwarded to port 3074 if you have an IPv4 based system. Otherwise if your network is IPv6 based port 3544 will probably not even be used. Quote from wikipedia reference Teredo:

"Teredo should be disabled when native IPv6 connectivity becomes available"

Hope this has made my posts a little more understandable. I'm just trying to help.
