What is the issue you’re encountering
Can’t figure out how to setup an application for access on port 873
What are the steps to reproduce the issue?
I currently have a Cloudflare tunnel setup that has access into my private network at home. I’ve exposed one application so far. This application is a web service that I can hit from outside my network. It has a policy setup where it’ll send me a one time pin to my email and then I can access the application. It’s great.
Well now, I want to leverage this tunnel to permit my brother’s NAS to send its daily backups to my NAS. Prior to today, I’ve just had a site-to-site VPN setup between our houses and so his NAS (192.168.13.50) could send its backups through the VPN directly to my NAS’s IP address (192.168.188.240) on port 873. I no longer want to maintain this site-to-site VPN and want to leverage cloudflare to provide the connectivity. I want to use a Cloudflare zero trust solution.
An important detail to make here is that both of our NAS’s are Qnap brand NAS’s. They’re currently configured to use rsync to transfer the backups. I don’t believe I have the ability to install a WARP client on them. Essentially, I think I need them to be able to reach each other natively without installing additional software.
I have several questions about how to do this.
- How do I configure a new application in cloudflare to access an rsync server in my network on port 873?
- How do I configure the authentication/policy piece so that my brother’s NAS doesn’t need to authenticate (or even better automatically authenticates) with cloudflare to access my rsync server?
- The backup software on my brother’s NAS can only be configured with the following fields:
- Destination IP/hostname
- Port
- username
- password
- Could I simply configure the destination ip/hostname to be “offsitebackup.mydomain.com” on port 873 and have it go through the cloudflare tunnel to my nas?
I’ve attached a drawing of help illustrate the scenario.
