All in-repo path references (AGENTS.md, README, old scripts, report artifacts,
test code paths) rewritten in the same commit; focused-test map extended for
.gitignore, old/scripts/*, dankclaw/comfyui/*, and report/* per this repo's
own convention ('add one before committing'). Obsidian wikilinks are
title-based and unaffected.

# Network Architecture
|
|
|
|
One Caddy fronts both hosts. It runs as a container on Dankclaw (192.168.0.143) and terminates TLS for every service on the LAN. Pi-hole on Dankclaw answers the service names for LAN clients; Porkbun answers them for the WAN. The G36 router firewall governs external access. SearXNG outbound traffic exits through the Gluetun VPN container.

```
|
|
|
|
Dankserver runs no proxy of its own. Its services expose published LAN ports, and the Dankclaw Caddy routes the names to those ports.
|
|
|
|
## Hostnames
|
|
|
|
| Scope | Convention | Resolved by |
|
|
|-------|------------|-------------|
|
|
| LAN | `romm.franksdank.cloud` → 192.168.0.143 | Pi-hole (`addn-hosts`) |
|
|
| WAN | `romm.franksdank.cloud` → 71.227.227.172 | Porkbun A record |
|
|
|
|
Users type a name and nothing else. Caddy maps the name to the upstream. The split between the two resolvers removes the need for router NAT loopback. See [[LAN-DNS]] for the flow and the router hand-off.
|
|
|
|
## TLS
|
|
|
|
Caddy holds one Let's Encrypt certificate per vhost, issued and renewed through the DNS-01 challenge via the Porkbun module. No inbound port 80/443 is required. Details in [[Caddy]].
|
|
|
|
## Gluetun Path (SearXNG only)
|
|
|
|
SearXNG attaches to the Gluetun network namespace (`network_mode: service:gluetun`). Only SearXNG shares the tunnel. Everything else on Dankclaw uses the normal LAN route. This matches KB Pattern 2 in [[Gluetun]].
|
|
|
|
## Access Policy
|
|
|
|
- The **G36 router firewall** governs what the WAN can reach. Port forwards are manual router steps; the repo tracks no router state.
|
|
- Caddy adds HTTP basic auth on the homepage and on sensitive services.
|
|
- LAN subnet: `192.168.0.0/24`.
