If you open your login page to internet without security, someone one day will have a field trip inside your NAS files and will find all your “i know what you did last summer” photos.

I do have DS423+ and i am too using Cloudfare tunnel to access it from anywhere.

My CF Tunnel setup done like this:

Domain: nas.example.com points to http://1.2.3.4: and i have 2 access rules added.

One of these rules NEEDS to match otherwise - “You Shell Not Pass”
#1: Public IP needs to be matched as my public IP
#2: Person who wants to login needs to authenticate via Google Authentication. Google authentication needs to match test1@gmail.com or test2@gmail.com

While i am at home, i use nas.example.com to access my nas instead of using its local IP and cloudflare allows access with no questions asked.
While i am outside my home network i get asked to authenticate via google and gain access this way.

+CF Tunnel adds https automatically for me.

I don’t use any firewall setup or any other rules inside NAS.
