- Remove AdGuard Home from all service catalogs, deployment phases, persistence tables, and network architecture docs - Update Technitium notes: authoritative .ai.home zone, recursive resolver, DoT forwarder to Cloudflare (tls://1.1.1.1), built-in ad blocking - Resolve open questions #2 (Technitium upstream) and #3 (AdGuard layout) - Add dns-topology.md: complete DNS architecture diagram, zone details, client assignments, Tailscale integration, troubleshooting table, migration history (AdGuard deployed → paused → removed)

Ingress Flow
[Internet] → [Tailscale mesh] → [MK7: Traefik] → [Target Node: Service Port]
Traefik Role
- Single entrypoint. Every HTTP/HTTPS service routes through Traefik on MK7.
- Tailscale-native. Traefik binds to
0.0.0.0:80and0.0.0.0:443. Notailscale serve. - Service discovery via Docker labels. Each compose service exposes labels that Traefik reads from the Docker socket on MK7.
- Docker socket access restricted. Traefik mounts a read-only Docker socket. No other service gets socket access.
Internal Traffic Patterns
| Source | Destination | Protocol | Port | Notes |
|---|---|---|---|---|
| Traefik (MK7) | Any service | HTTP/HTTPS | Varies | Proxied via Tailscale IP |
| Beszel (MK7) | Any node | HTTP | Varies | Agent polls HTTP metrics endpoints (read-only) |
| Prometheus (MK7) | Any node | HTTP | 9100 (node-exporter) | Scrapes node and container metrics |
| Prowlarr (MK7) | Indexer sites | HTTPS | 443 | Outbound only |
| Sonarr/Radarr (MK7) | Prowlarr | HTTP | 9696 | Internal indexer lookup |
| Nextcloud (MK7) | PostgreSQL (MK7) | TCP | 5432 | DB traffic over Tailscale |
DNS Resolution
| Component | Status | Detail |
|---|---|---|
| Technitium (MK7) | ✅ Deployed | Container running, port 53/5380 open |
*.ai.home zone |
⏳ Pending | Not yet configured as authoritative — Tailscale MagicDNS currently handles name resolution |
| Technitium DNS (MK7) | ✅ Active | Authoritative .ai.home + recursive resolver + ad blocking on port 53. |
Planned Chain (not yet active):
Client → Technitium (local record?) → AdGuard Home (recursive + blocklist) → Upstream (Cloudflare/Quad9)
Current Fallback: Tailscale MagicDNS provides *.ai.home resolution via Tailscale IP addresses. Technitium will assume authority once zone records are populated.
- AdGuard Home admin UI runs on port 3000.
Port Allocation (Reserved)
| Port | Service |
|---|---|
| 53 | DNS (Technitium / AdGuard) |
| 80/443 | HTTP/S (Traefik) |
| 3000 | Grafana |
| 9090 | Prometheus |
| 9000 | Portainer |
| 8096 | Jellyfin |
| 8989 | Sonarr |
| 7878 | Radarr |
| 9696 | Prowlarr |
| 8080 | Authelia (default) |
TLS Strategy
- Internal: Traefik generates self-signed certs for
*.labs.internal. Authelia can enforce client-cert if needed. - External: Not applicable per no-Tailscale-funnel constraint. If Bobby later wants public access, Let's Encrypt via DNS challenge (Technitium controls the zone).
