I’m a network newbie so I have no idea about the importance of this. I have done port forwarding in my router before, mainly so I can access my Plex system outside of my house. I used to setup port forwarding when torrenting but I have realized that I can still get my Linux ISOs without it. I never cared even though I’m a heavy user of their product. When will it start to affect me, or in other words, what use cases am I locked out of when port forwarding is disabled?
