Seting up synology file sharing via cloudflare tunnel

What is the name of the domain?

What is the issue you’re encountering

I would like to use activate file sharing on Synology nas, but a firewall is set up on the local network that blocks access to the nas from the external network. I have set up cloudflare tunnel to make services on the nas publicly accessible and would like to know if there is way to also make file sharing work?

file sharing

May I ask how big files or how large would they be and sharing them over a HTTP(S), or some other way via some specific port or a service like rsync, SAMBA, FTP, etc.?

Hello,

Yes you can allow this via Cloudflare Tunnel.

To do this you must :

• Create an application in Cloudflare Zero Trust under : Access/Applications
• Name your app and in Application domain section, authorize your subdomain with the following paths:

wfmlogindialog.js
sharing/
webman/
fsdownload/

• Then, in the Policies tab, create a Bypass rule (this is an example)
• Save your application.

Once you’ve done this, you should be able to access your share file as long as your Synology share address starts with: https://your-domain-name.com/sharing/...

You can of course fine-tune the rules in Policies to authorize only certain people to access your service
