I have a private IP address, Orange LTE 4G, router B315 LTE CPE. I would like someone to dispel my suspicions and tell me if Orange is really blocking ports, can you ask the operator to disable port blocking and whether it will be safe if I have purchased Norton anti-virus and asymmetrical NAT settings on the router. Should I then be afraid of attacks via the Internet or if I am a gray man who sometimes plays with friends through hamachi, steam, uplay, the origin of the game does not threaten me?
