NAT issues are a common problem on PlayStation 4, and there are a few ways to fix it. Here are three tips:

  1. Disable NAT on your PlayStation 4. This will stop your PS4 from using the network to connect to other devices, which can cause problems with voice chat and gaming.
  2. Use an external microphone and speaker for voice chat. This will allow you to use your own voice instead of the PS4’s built-in microphone and speaker.
  3. Use a VPN service for gaming purposes. This will help you hide your IP address and protect your privacy while playing games online.
