NAT type strict and server connectivity blocked, unable to play online | Win10

Hi

while playing FH4 i found out that i’m unable to connect to online sessions.
After doing a bit of research i found out that on the network settings page in the xbox programm the NAT-type is set to strict and he serverconnectivity is blocked.
Now i’m not a very techy guy and i’m a bit cautious when it gets to changing IP adresses and all that stuff.

What i’ve done so far,

So far i have checked what services are running by using these instructions;
https://support.xbox.com/en-US/xbox-on-windows/social/server-connectivity-xbox-app-displays-blocked

however it appears that i am missing certain services(?).

i do have;
IKE and AuthIP IPsec Keying Modules
IP Helper
Xbox Live Auth Manager

but i don’t have;
Xbox Live Networking Service ( maybe this is causing everything and simply solving that would fix the rest? )

Further more i have taken a look at changing all my ip adresses to static IP’s, however this stuff scares me as i have no idea about what i’m doing.
this is the website i tried to use for that;
https://support.xbox.com/en-US/xbox-on-windows/social/troubleshoot-multiplayer-game#Open

Again, i have no clue on how to fix this and what is actually causing it.
Can someone please try to help me out?

Thanks in advance.
