Nicolas Cantu b9157d12b0 Point ia.enso nginx upstreams to IA host 192.168.1.173

**Motivations:**
- Ollama and AnythingLLM moved from 192.168.1.164 to the ia LAN host.

**Root causes:**
- Upstreams still targeted 192.168.1.164.

**Correctifs:**
- Set upstream servers to 192.168.1.173:11434 and :3001.

**Evolutions:**
- Docs aligned with ia role IP; note to edit site conf if IP changes.

**Pages affectées:**
- deploy/nginx/sites/ia.enso.4nkweb.com.conf
- deploy/nginx/README-ia-enso.md

Feature: Reverse proxy ia.enso.4nkweb.com for Ollama and AnythingLLM

Author: 4NK team

Objective

Expose Ollama and AnythingLLM on the public proxy hostname with HTTPS, path prefixes /ollama and /anythingllm, and gate Ollama with a Bearer token checked at the proxy (compatible with Cursor’s OpenAI base URL + API key).

Impacts

Proxy (nginx): new server_name, TLS, locations, HTTP map for Bearer validation; maps deployed under /etc/nginx/conf.d/ when using the provided script.
Backend (192.168.1.173, role ia): must accept connections from the proxy on 11434 and 3001; Ollama must not rely on the client Authorization header (nginx clears it after validation).
Clients: Cursor uses https://ia.enso.4nkweb.com/ollama/v1 and the shared secret as API key; avoids private-IP SSRF blocks in Cursor when the hostname resolves publicly from the client infrastructure.

Repository layout

Path	Purpose
`deploy/nginx/sites/ia.enso.4nkweb.com.conf`	`server` blocks, upstreams to `192.168.1.173` (edit if IA host IP changes)
`deploy/nginx/http-maps/ia-enso-ollama-bearer.map.conf.example`	Example Bearer `map` (manual install)
`deploy/nginx/http-maps/websocket-connection.map.conf.example`	Example WebSocket `map` (manual install)
`deploy/nginx/deploy-ia-enso-to-proxy.sh`	SSH deploy: maps + site, `nginx -t`, reload; Bearer-only retry if websocket `map` already exists
`deploy/nginx/README-ia-enso.md`	Operator reference: automated + manual steps, env vars, checks, troubleshooting

Deployment modalities

Preferred: run ./deploy/nginx/deploy-ia-enso-to-proxy.sh from smart_ide on a host with SSH access (see README-ia-enso.md for prerequisites and environment variables).

Manual: DNS → TLS (certbot) → install map directives inside http { } (via conf.d or http-maps includes) → install site under sites-available / sites-enabled → nginx -t → reload. Details: deploy/nginx/README-ia-enso.md.

Restrict backend ports on the IA host (192.168.1.173 in repo config) to the proxy source where a host firewall is used.

Analysis modalities

curl to /ollama/v1/models with and without Authorization: Bearer <secret> (expect 200 / 401).
Browser access to /anythingllm/ and application login.
Cursor connectivity after configuration (no ssrf_blocked if the hostname does not resolve to a blocked private IP from Cursor’s perspective).

Security notes

The Bearer secret is equivalent to an API key; rotate by updating the map file and client configs together.
AnythingLLM remains protected by its own application authentication; the /anythingllm location does not add the Ollama Bearer gate.
A public URL for /ollama exposes the inference endpoint to anyone who knows the secret; combine with network controls if required.
