# Network access: ai.home / ai.haylan.ch

Open WebUI is meant to be reachable as **`ai.home`** on the LAN and **`ai.haylan.ch`** from outside. This stack doesn't run its own reverse proxy — it publishes Open WebUI's port to the host (`${WEBUI_PORT:-3000}`, see `docker-compose.yml`) and relies on the **existing Nginx Proxy Manager (NPM)** instance already fronting other self-hosted services on this network.

## What to set up in NPM

Two Proxy Hosts, both pointing at this machine's LAN IP on port `${WEBUI_PORT:-3000}` (Open WebUI):

- **`ai.home`** — internal only, no external DNS/TLS needed unless you want it.
- **`ai.haylan.ch`** — external, reachable via the DMZ already forwarding it to NPM; let NPM issue/manage the TLS cert as it does for other services.

## llama.cpp's raw API stays LAN-only — deliberately

The inference API (port `${LLAMA_PORT:-8080}`) is **not** registered in NPM and is **not** reachable via `ai.haylan.ch`. It has no authentication of its own (unlike Open WebUI, which has login enabled) — putting it on the public internet would mean an unauthenticated inference endpoint. Coding-agent CLIs (Claude Code, Kimi, OpenCode — see `docs/coding-cli-setup.md`) reach it directly over the LAN, using this machine's LAN IP or `ai.home` if your local DNS resolves that hostname straight to the box (bypassing NPM, which only fronts ports 80/443).

If you later want external CLI access too, that's a deliberate scope change — see the map ([issue #1](https://git.arthurerlich.de/haylan/LLM-Server/issues/1)) before doing it, since it changes the security posture (the raw API would need its own auth in front of it).

## The AI proxy (LiteLLM) — `proxy.ai.home` / `proxy.ai.haylan.ch`

Once the gateway from [issue #9](https://git.arthurerlich.de/haylan/LLM-Server/issues/9) is deployed, it gets its own hostnames, same NPM pattern as Open WebUI above:

- **`proxy.ai.home`** — internal only, fronts the full LiteLLM port (API + Admin UI).
- **`proxy.ai.haylan.ch`** — external, via the DMZ/NPM. Fronts only the inference API paths.

**Every proxy call already requires a valid virtual key** (Bearer token, see `docs/proxy-key-onboarding.md`) — the same bar Open WebUI clears with its own login — so no extra NPM-level auth is needed for the external hostname.

**LiteLLM's Admin UI (`/ui`) stays LAN-only**, same reasoning as llama.cpp's raw API: it manages every workload's keys and budgets, so it doesn't belong on the public internet. LiteLLM serves `/ui` on the same port as its API by default, so `proxy.ai.haylan.ch`'s NPM Proxy Host needs an explicit rule denying the `/ui` path (a "Deny" custom location, same UI as the "Advanced" tab used for other NPM hosts) — `proxy.ai.home` has no such restriction and reaches both the API and the Admin UI.
