I am having a lot of issues with my NAT type when playing Call of Duty on my xbox one.
I have discussed this with Activision support and they are happy with all the details i have given them.
The NAT type for my Xbox is open and always has been but for COD it seems to be moderate or strict and i have lots of trouble joining my friends in a game lobby.
I have been through the static IP address set up and the prot forwarding but this does not seem to make a difference.
Currently i have delested all of these settings as they have been doing nothing towards helping my issues.
I ran a WIFI speed test and was getting 2.1 Mbps and a hard wired test and was getting 4.6Mbps, surely there must be an issue here as i am paying for the top broadband every month, for many years, and i seem to be getting a very poor service from Virgin at this moment in time.
