How To Fix Strict or Moderate NAT in COD Vanguard

Last Updated on January 14, 2022

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.

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.
