June 4, 20251 yr Hi!Being new to Unraid and slowly learning, I try to understand how things works. And in particular when I have to change a default settings that could have security implications. To be able to access my Docker containers on the same IP addresses when connected to my home network as well as remotely using Tailscale, I've understood that I have to enable Host access to custom networks for Docker. But there is a warning to only do so if you understand what that means. And I'm not sure I do, yet. :)With it disabled, all services as well as Unraid OS itself doesn't seem to be able to communicate between each other unless the network is set to host. I guess this is part of the compartmentalization in Docker, isolating containers from each other. But that would mean that there also is at least some security aspect of enabling Host access to custom networks?Or are there other reasons this is off by default?If it matters, I'm not planning to expose anything on my Unraid server on internet, only remote access for me and my family using Tailscale.

Without this options, the docker network is isolated from the unraid lan subnet IP. Thus preventing some comunications with some dockers.
