# How to Create Network Diagrams with ChatGPT

ChatGPT creates network diagrams while suggesting security and architecture improvements. It identifies potential single points of failure, recommends segmentation strategies, and can generate separate diagrams for physical and logical topologies. Infrastructure planning and documentation happen together.

## Setup

{"mcpServers":{"toolrouter":{"command":"npx","args":["-y","toolrouter-mcp"]}}}

## Steps

1. Configure ToolRouter in ChatGPT
2. Ask: "Generate a network topology diagram" and describe the network components
3. ChatGPT creates the diagram with proper device groupings and connections
4. Request: "Add a VPN tunnel between the office network and the cloud VPC"

## Example Prompt

```
Draw a network diagram for our hybrid setup: on-premise data center with a core switch, connected via VPN to AWS VPC with public and private subnets, NAT gateway, and an RDS instance in the private subnet.
```

## Tips

- ChatGPT can suggest security improvements based on the topology it generates
- Ask for separate diagrams for physical and logical topologies if needed
