Call of Duty: Vanguard connection & NAT issue on PC/PlayStation/Xbox

If the NAT type is Moderate/Type 2 or Strict/Type 3 in the game’s Settings menu, you may experience connection problems while playing Call of Duty Vanguard.

Open/Type 1 NAT will provide the best connection quality for Call of Duty Vanguard on PC or gaming consoles (PS4/PS5/Xbox).

How to fix NAT issue in Call of Duty: Vanguard

How to fix NAT issue in Call of Duty: Vanguard

You can fix the NAT problem and improve the connection quality in the game by trying the solution methods below.

Check your network status on PC

If you don’t want to have NAT problems in the game, make sure the network status is private in Windows settings. Rarely, after a Windows update, the network status may change by itself.

  • Go to Windows Settings > Network & Internet > Status
  • Click on the Properties button
  • Select Private
Private network

Port Forwarding (PC/PlayStation/Xbox)

The other thing you need to do to change the NAT type to Open/Type 1 is port forwarding. Or, if your router supports it, just enable DMZ and enter your device’s IP.

Note: Do not use DMZ vs Port Forwarding at the same time.

You can use the following ports for Port Forwarding/Port Triggering.

TCPUDP
COD Vanguard Windows PC Ports3074, 27014-270503074-3079
COD Vanguard PS4/PS5 Ports1935, 3478-34803074-3079, 3478-3479
COD Xbox One & Series X/S Ports307488, 500, 3074-3079, 3544, 4500

UPnP (PC/PlayStation/Xbox)

If your router supports UPnP, check it and change its status (Enable/Disable). UPnP has both caused and fixed problems in the previous Call of Duty games.

Note: If you are enabling UPnP, don’t forget to disable Port Forwarding and DMZ.

You should also take a look at the “Test your home network” section in Activision’s guide.

Check your firewall and antivirus

You should allow Call of Duty Vanguard from your firewall and add the game to the exceptions list in your antivirus software.

  • Try this steps if you are on PS4-PS5.
    1. Enable or disabled Port Forwarding
    2. Enable or disabled UPnP
    3. Enable or disabled DMZ
    4. Switch DNS (Cloudfare, Google, OpenDNS)
    5. Connect to a phone hotspot and see if it works.
    6. Reset your router.
    7. Switch out your router for another one

    Remember for each steps you need to restart the router and your console.

    If none of the steps works above then try to remove your games saving and put your console to safe mode and update (reupdate) your system.

    For me it worked first when I disabled the UPNP for a day and half. Later the next day it stopped working to so I reupdated the console and it worked, so now I’m struggling with my ping. Shit keeps finding servers with above 200ms and it’s unstable. Hope to helps at least!
