Database connection

[Vinicius_Rodrigues]

Hello!

I’m developing a web application that requests data from a local server. This server has the data stored on a sql server. A solution I found to read this data is to establish a VPN connection between the web application and the local server. I’m using upload via docker image. The system is working locally, when I run it on my computer it works as expected. However when I run it in render I get the following error:
" mknod: /dev/net/tun: Operation not permittedchmod: cannot access ‘/dev/net/tun’: No such file or directory"
In some research I could get the result that the render does not support the use of tunneling to create a VPN connection.
My question:- Does the render really not support the vpn tunnel? Is there any way to configure?- Is there any other solution to access data from a local server securely?

Hi Vinicius,

The most straightforward approach for connecting external private resources to your Render services would be with Tailscale. See https://github.com/render-examples/tailscale for an example of how to use that service.

That being said, I think you’d be better off with your local server pushing data to a database hosted on Render and then have your service read from that database if at all possible.
