Server setup with static ip

Plan:

1. Install Nginx on Dell as reverse proxy

2. Configure virtual hosts in Apache (iMac) for 10 domains

3. Point all 10 domains to your static IP via DNS

4. Route traffic through Dell to Apache by hostname

5. Create separate endpoint for AI service (auth-protected)

6. Set firewall rules on Dell to allow only necessary ports

Phase 1: Parallel setup (keep TP-Link as backup)

• Keep current setup working

• Test Dell router with just a few devices

• Make sure everything works perfectly

Phase 2: Switch WAN connection

• Move cable modem to Dell enp3s0

• Configure TP-Link as access point only (disable its DHCP)

• Dell becomes main router for 192.168.0.x network

Diode – semiconductor, low-cost engraving

CO₂ (DC Glass Tube) – midrange cutting, hobby to production

CO₂ (RF Metal Tube) – high-end engraving, precision cutting, industrial reliability

Fiber – metal marking/cutting

DPSS / Nd:YAG – precision metal marking, jewelry, semiconductors

They are a type of CO₂ laser, but instead of being DC-excited glass tubes (like most Chinese imports), RF tubes use radio-frequency excitation and metal or ceramic enclosures.
So while they share the same wavelength (10.6 μm infrared light), the construction and performance are completely different.

What Is Ollama?

**Ollama** allows you to:

- Download and run popular open-source LLMs (like Llama 3, Mistral, Phi-3, Gemma, etc.) directly on your laptop or local server.

- Run these models **locally**, meaning no data leaves your device.

- Interact with models via a simple CLI (command-line interface) or API.

- Customize and fine-tune models for specific tasks.

Think of it as a **local AI assistant toolkit**

 create a local API server that allows LM Studio to "learn" from your Chroma database, here's a complete solution:
