Tailscale is a zero-config VPN service built on top of Wireguard. It's great for accessing devices and applications behind firewalls, and you can use it to connect to all your private services on Render with this repo.
Tailscale subnet routers act as a gateway to your Render private network, enabling connections to any and all internal IPs (of the form 10.x.x.x) in your Render network.
Use the button below to deploy a Tailscale Subnet Router on Render.
Deploying this repo will create a subnet router in your Tailscale network. Once it's up and running, you can connect to any private service by looking up $RENDER_INTERNAL_IP in the web shell.
