Actual root cause (operator-directed layered MTU check): Cilium runs VXLAN (routing-mode tunnel) so pods get MTU 1450 (1500-50 encap) while node, hypervisor, and the Google Fiber WAN are all 1500. OpenVPN's ~1500-byte handshake packets exceed 1450 and are dropped (PMTUD broken). The ports were a red herring. Fix: OPENVPN_MTU=1350 + OPENVPN_MSSFIX=1350 so encrypted packets (~1402) fit under 1450. Keeps OpenVPN + VXLAN unchanged. Re-enable vpn-egress. Full layered trace (pod/node/host) in DECISIONS-LOG.

home-network-k3s-impl
Implementation of the home k3s + Longhorn platform. This repo holds the reconciled artifacts
(Flux config, Kustomize overlays, KubeVirt/Helm manifests, ServiceDefinitions, Kyverno policies,
Chainsaw conformance tests, CI). It is driven by — and subordinate to — the read-only
specification at ../home-network-k3s.
Rules (from the spec — non-negotiable)
- The spec is read-only. Never modify anything under
../home-network-k3s. Implement against it; escalate spec problems, don't edit them (specAGENTS.md§11, R-TEST-06). - Done = a green, reproducible, requirement-tagged conformance test — never "merged," never a
manual demo (spec
docs/14,agents/definition-of-done.md). - No work on
main. Every change is a feature branch merged intomain(specCONTRIBUTING.md). - No plaintext secrets — SOPS-encrypted only (spec
docs/07). - Phase discipline — only build what the active roadmap phase authorizes (spec
roadmap/phases.md).
