Call of Duty Vanguard, the new offering in the Call of Duty franchise, also suffers from networking issues. One of those issues is NAT, which creates problems for users while trying to connect to the other players. The network needs a clear pathway to connect to other users. In case there are problems, the game will show, NAT type as strict or moderate. This leads to issues with voice chat, lobbies, and broken game connections.

Having an Open NAT lets you chat with people, join interconnected VOIP servers, host multiplayer lobbies and so on. Anything that requires your internet connection.
What problems do Strict and Moderate NAT Create?

Let’s understand what Open/Moderate and Strict NAT are and what issues they will create.
- Open – Seamlessly join games, voice chats, host multiplayer lobbies and perform game network-related functions.
- Moderate – You will never be chosen as the host of a game, and you will have trouble joining matches hosted by other players.
- Strict – Strict NAT type is the worst. If you have this NAT type then you’ll only be able to connect to Open NAT users. Also, You will never be chosen as the host of a game.
You can find what your NAT type is by opening up the game.

Still not fixed Xbox one s all other cod games open Nat I have direct 200mb fibre connection and stuck in moderate Nat for vanguard multiplayer. Even put Xbox in DMZ doesn’t work. I cannot join a game with less than 100ms ping and can only play hardcore to even get a decent chance of a kill.
