Router setting says "Cone" type which should mean "open". Turned uPnP too, restarted router in every way and even tried mingling with some destiny 2 ports, although don't know much about it... Game always gives me error which says i'm using STRICT NAT network and how it will affect my in-game experience ***(which does happen since I cannot join everyone's game and cannot hear anyone's voice in fireteams)*** I am using 4G LTE router which is connected to the PC with cable (internet is not bad and it's quite stable, this is the first major problem I encountered) Do you have any idea what might be the problem and how to resolve it? Any assistance will be appreciated !
