Thanks for your answers. My question was, I believe, a little ambiguous and more focused on the router-side of the configuration.
Unfortunately, after trying to setup My Servers, I saw that my server could only be accessed via the "https://yourhash.unraid.net" address, and as my network is sometimes disconnected from the internet, this functionality made the address impossible to resolve.
In short, if disconnected from the internet, my server's webui is unavalaible even from my LAN. I did not have time to find a workaround around this, so I reverted to my previous config, without My Servers enabled.
I will look further into it as soon as I can, and eventually make a dedicated topic.
In the meantime, I really wanted to thank you guys for your help!
