As the title says. For example, all devices in our VPN have the same common public IP. It would be great if only those devices connected to our VPN have access to a web app on render. I hope this works in the free or basic tiers.
This isn’t a feature that we presently have. There’s a feature request for this at https://feedback.render.com/features/p/restrict-web-services-access-by-ip which I would encourage you to upvote,
