  1. followed step by step works like a charm 🙂 I was having issues with my router and got to the activision page they have other ports for this game I tried them also work normally really thanks!

  2. This doesn’t work I think he made fake comments because if you look at pretty much all the ones with pictures they said it didn’t work but the ones without pictures did

  3. I wish the developers showed an example of you entering it rather than just giving the figures, similar to what you’ve done here, would save me the hassle. I didn’t realise it had to be done for both internal and external and what the difference was.

    Despite this^ I did do it correctly just by assuming, I did it exactly as you’ve shown here but it still doesn’t work.

    Annoying as hell and my ISP is completely usless.

  4. I just changed to BT FTTP and have a new router which was showing a moderate NAT on PS5. Followed these instructions and it work straight away!

    No need to reset router or anything.


  5. Someone help I got 2 sets of port numbers for ps4 I don't know which ones to use first is this TCP:80,443,3478,3479,3480 UdP: 3478, 3479 the other numbers are TCP: 80,443,1935,3478-3480, UDP: 3478-3479 if someone knows which is the correct one let me know

  6. I already have these ports set for my ps4 automatically but I also have others listed in my forwarding rules that aren't listed here, do I have to remove other ports to get open nat or are they for something else? Sorry I don't port forward often.

  7. This videa explaned a lot and i learned much about these kind of problems now. Really well explained, to the point. Made me sub to the channel (i rarely sub).

    However it did not help the issue completely, went on a forum of my internet provider, they had some other possible solutions and similar. However 1 did the trick.
    Windows defender, but not the advanced option. hope it's ok to share this link as well to help people who still looking for more options (or just add this to your own video).
    Can not say if this link did all the work or the combination of both. But my NAT type is finally open and i'm able to play crossplatform zombies with my friends without dc's (for now)

    Thank you sir! you're doing a good job!

  8. Great helpful video. I found that using my pc IP address didn't work with my Plusnet router at first. So I had to select the device out of the drop-down list. Thought id comment for anyone else who is struggling.
