HOWTO: Validate Network Architecture End-to-End¶
This HOWTO validates the shipped on-prem network reference topology across VLANs, routing, inter-VLAN firewall policy, NAT, and observability paths. The checklist proceeds from the Proxmox host outward, tests each layer in sequence, and captures structured run records suitable for the post-change validation gate.
What this covers:
- Layer-by-layer validation sequence: VLAN gateways, routing table, firewall policy, NAT, and observability
- Run-record pattern: storing validation outputs under
logs/networking/arch-validation/ - Post-change validation flow: confirming no regressions after network configuration changes
