Please do not open ports and turn on UPnP this will only cause connection/NAT problems. If I am not mistaken there are 4 steps in obtaining open NAT in support instructions. Clear ports, and check mark the UPnP ENABLED. If you are using a gateway router/modem you may want to bridge it and get an approved Router from the list of approved routers . I have done this with a Motorola Surfboard and my new Router is a NetGear WNDR4700 hardwired to the 2 Xbox Ones. Good Luck Got bounced between Xbox Live and my internet supplier for 2 days finally did this and works fine and has stayed open.
