Hi! All of a sudden for example Destiny 2 and my PS4 started giving me warning that my NAT type is "Strict". Both PC and PS4 access the internet via the same 4G router, PC via LAN, PS4 via WiFi. Router is Huawei E5186. I've not knowingly changed any network security related settings yet get this warning. I'm assuming this is a router setting as the console also gives the warning. Only thing I did change just now is switch the PS4 to 5 GHz WiFi. Could it be the router defaults to and forces strict NAT if 5G is used? Or if both 2.4G and 5G are used at the same time? I also connect my phone via WiFi to internet when I'm home. Thanks!
