I have Plex, Radarr, Sonarr, Overseerr etc running in Docker containers, but have never found a good guide on how to access these (safely) from outside. I resort to connecting to a server running VNC. I’ve tried nginx but didn’t understand it, also tried Cloudflare (ditto). Is there a good, easy to understand guide on how to do this?
You’ve been given a the usual variety of suggestions, but I suggest also gaining an understanding of networking principles, including RFC 1918 addressing and NAT.
