I’m using Plex/ docker and it just keeps flicking the switch for outside access it only works when I manually port forward my router which I don’t wanna do. Is there any fix for this
what’s wrong with a manual port forward?
personally I prefer disabling UPnP to avoid all kinds of apps publishing themselves to the internet
I thought you’d have hackers if u port forward and delete my stuff.
If you publish your server, it’ll be exposed to the internet. That’s independent if you’re using a manual port forward or an automatic configuration like UPnP. With UPnP however it’s the individual app that decides it’ll publish something to the internet (ideally because you configured it that way) – with a manual forward, you expose exactly what you want to be exposed.
Exposing your server on its own is not necessarily a problem unless there’s a security gap that hacker can use. The most common vector will be “getting the password somehow” and to simply log into the server.
Personally I like that I can pick a mostly random port for my manual port forward. While a serious hacker will have other means to identify what application I have exposed… at least it’s not the obvious default public port (32400)
