I'm not sure I understood what I need to do and how. By the way, you mentioned VPN. I have to say that I use two VPNs. One is Forticlient - that I use to connect to my office's server when I work from home. And HMA VPN that I use to change country location,
also for work.

Are you saying that those VPNs affect the NAT? If so, I closed both of them and the NAT is still strict.

Hi Sebastiandm.com

Basically two vpn`s will collide its too strict of a firewall it will not allow your nat type to be open it will keep moderating it automatically i used to work for a company called telewest communications laying down fiber optic broadband and tv cables
installing internet into customers homes

A vpn can cause all sort of issues in the gaming community if its too tight basically you have the modem which has a router and firewall built in you also have a router which also has a built in firewall then your vpns add 2 extra layers of security so it
is going to keep testing your nat type as strict at all time`s

But if you`r using the vpns to work from home that will be a major problem with your connection it may be worth investing in a online vpn to mask your ip but with your actuall ip being static and starting with 192.168 this is automatically recognized as
a briddged ip connection which is all ready masked by your subnet mask your actuall isp ip isnt visable to anyone else even with those added layers of security i can understand why you think you would need all that security

with the web being how it is these days my advice would be see if your isp can give you ipv6 this way the ipv4 can be used for your home pcs and the ipv6 will run the console and computers so you will still have your vpns but the ports wont get congested
and lock out your console

you can check on these links for issues with your connections and also if you have ipv6

https://ipv6-test.com/

https://test-ipv6.com/index.html.en_US

use both links the first one will test your ipv4 and ipv6 for any issues

the second one will tell you if you have ipv6 you should have a score of atleast 9 out of 10if you have ipv6 enabled it will tell you on both sites if not then you will need to contact your isp and ask them to enable ipv6

ipv6 is becoming more populare and is what most websites are now using without ipv6 it makes it harder to connect to certain sites so for instance it could be causeing issues with you`r console aswell so eaither way the two vpns are going to keep encrypting
the ping to the nat type test strict nat type stops you being able to play multiplayer games and hosting games alltogether moderate lets you play games co op and open allows hosting of games and connecting to p2p servers enabling packets to be recived and
pinged to the servers right now your loosing packets and not reaching most of the servers or benafits through your console due to these issues

There maybe more help through a support agent by calling microsoft and getting them to go through your vpn settings and firewall settings but test to see if you have ipv6 first and see if your isp will enable it other than that i can only recomend that you
call microsoft support as i have gone over everything i know possible to my knowladge

Kind Regards Ambassador

Hi, thank you for replying. Actually I use only one the modem. I don't have a router. I have another modem that I'm not using (D-Link modem), do you think it's better if I use this D-Link modem as router?

XBox, for some time now, is not reporting NAT statuses properly.

To test this, I plugged my XBox One X directly into the modem. No router or anything in between. My ISP assigned the XBox a route-able IP address (Meaning an actual internet IP address and not a LAN IP address) and I waited while the XBox detected the NAT
type. There isn't one, mind you, when you're connected directly to the modem. It came back as STRICT. Changing from Online to Offline, then back to Online and I got STRICT again, so I ran the networking tests from the XBox and it came back with "All Services
Available" which translates to a completely open network.

Plugging my router back in and reconnecting the XBox, I tested again. This time, it said Moderate! My XBox is set in the DMZ, so no port forwarding or IPSec settings to mess with (Besides IPSec will only become active when connecting to a VPN that requires
it) so it should be showing as OPEN. Testing networking services again and all services are available.

Taking the XBox out of the DMZ and let PNP do its thing also resulted in STRICT, yet all services were available.

The bottom line here is, the XBox's detection of NAT statuses isn't 100%. IF you can run the network services test on the XBox and it comes back with all services available, chances are, it's just misreporting NAT status.

If you're seeing the NAT status randomly change in COD Modern Warfare, ignore that completely unless you get errors with Microsoft services.

i never thought about that my bad sorry
