How to Access Immich in local network with the same url as outside local network

Hi friends,

I have setup a local Immich in my home, with Desktop Docker some months ago. All works fine and smooth. I use to do the updates and change according to instructions.

Also in Docker I am using nginx as proxy host. I have set in a domain that I have a dynamic DNS so I can access Immich while I on the go (outside local network). So when I'm not in my local network I use to login Immich https://--------------.com and all goes smooth.

But when I am at home, I cannot see or upload any photos/videos, unless I change the address to: http://192.---.---.---:2283

My goal was to use always the url address being in my local network or not.

Is that possible? How?

Thanks
