Expose selected workloads through floating IP mapping and controlled NAT behavior.
9 min read · Updated 2026-04-01
Prerequisites
- • Router connected to external network
- • Instance ports on private subnets
- • Security group policy for externally exposed services
Implementation workflow
This runbook focuses on a reliable sequence for provisioning and validating the service through the cloud console.
- Open Network > Floating IPs and allocate addresses from the external pool.
- Associate floating IPs with target instance ports.
- Confirm router SNAT behavior for outbound internet connectivity.
- Apply security group rules for only required inbound ports.
- Validate inbound and outbound connectivity from authorized sources.
Validation and operator checks
After deployment, verify connectivity, security boundaries, and backup posture before promoting workloads to production.
Operator tips
- • Allocate floating IPs only for workloads that must be publicly reachable.
- • Keep management access paths separate from customer-facing endpoints.
- • Review unused floating IP allocations to reduce waste and attack surface.
