OCI Free Tier DataRelay Link Server
This guide prepares an OCI Ubuntu 24.04 host with a persistent Reserved Public IPv4 address for DataRelay Link. It preserves the original OCI Console screenshots, while current product installation and Managed Host onboarding continue through the v2.4 documentation below.OCI Console labels, Free Tier eligibility, capacity, and pricing can change. Check the current Console’s Always Free Eligible indicator and cost estimate before creating resources. Oracle also documents that idle Always Free compute instances may be reclaimed after a sustained low-usage period, so do not treat a Free Tier VM as an SLA-backed production host without reviewing the current OCI policy.
What you will build
The deployment uses one OCI Reserved Public IP to front the DataRelay Link server, while each remote client publishes one or more local or reachable LAN services through its assigned persistent public ports. For this OCI walkthrough we use Enterprise single-443 because it gives a simple public policy:
Direct mode is also fully supported. In Direct mode, TCP 6099 is a separate public enrollment/management endpoint.

Part 1 — OCI network and VM
Create the VCN, Internet Gateway, public subnet, ingress rules, Ubuntu VM, Reserved Public IPv4, and verify SSH access.
Part 2 — Install DataRelay Link
Prepare Ubuntu, install and verify the Server, check reboot persistence, and enroll the first Managed Host.
The two parts preserve the original field-deployment screenshots. Splitting the guide only improves navigation; it does not change the deployment procedure.
