Wire services end-to-end: Caddy reload, NAT reflection, port forward
Fully wired service proxy deployment: Backend: - /api/services/status: full checklist (OPNsense API, SSH, NAT reflection, port forward 443, Caddyfile.services, service count) - /api/services/enable-nat-reflection: enables NAT reflection on OPNsense via SSH config.xml edit + filter reload - /api/services/create-port-forward: creates WAN TCP 443 → Caddy port forward via OPNsense NAT API, tracks rule UUID - /api/services/deploy: writes Caddyfile.services, reloads Caddy (tries docker compose exec, then restart, then systemctl), checks NAT reflection status, verifies port forward exists Infrastructure: - docker-compose.yml: mount Caddyfile.services into Caddy container, switch-manager volume writable (for writing Caddyfile.services) - Caddyfile.template: auto-imports /etc/caddy/Caddyfile.services Frontend: - Setup Checklist panel with green/red dots for each prerequisite - Enable NAT Reflection button (one-click) - Create Port Forward button (one-click) - Deploy button writes Caddyfile, reloads Caddy, verifies everything - Caddyfile preview in deploy results https://claude.ai/code/session_01Do9bsN39MTuy2GVv7yzSrE

Full deploy: write Caddyfile, reload Caddy, ensure NAT reflection

Architecture:

- Caddy runs on the LAN management computer (reverse proxy for all services)

- WAN: port 443 forwarded to Caddy — only port exposed externally
|

- LAN devices: reach services directly via Caddy

- Isolated VLANs (IoT, Guest): use public FQDNs — OPNsense NAT

reflection routes internally without traffic leaving the network
