I have used a server with ‘unRAID’ in my home-LAN.
Run ‘duckdns’, ‘swag’ and ‘Apache Guacamole’ as a Docker and a Windows-10-VM on it.
Point port 80 and 443 from my Router to ‘swag’ → ‘Apache Guacamole’ → Windows-10-VM
… and configurated many days these configuration… really! many days!!!(I’m here a Noob…)
But after get it running(clipboard-using does not get really functional…), only 1,5 days later → our IT detect this and “classified as a international risk…” and blocked it…
So I want a secure browser-to-local-hosted-file-server-solution too!
(only the basic functions like read, write, edit, new, delete Files, follow the internal Links AND use the clipboard are necessary for me. More functions then are the cherry-on-the-pie! 
)
