I was getting a strict NAT in GTA Online, so I couldn't play with my friends. I tried port forwarding, but it didn't work because I was behind CGNAT. So, I bought a static IP from Airtel, and now my NAT type has changed to moderate without port forwarding. However, I still want an open NAT, so I tried port forwarding again, but it is still showing that I have a moderate NAT. How do I open my NAT? my router: ZTE F670LV9.0
