NAT Traversal
A technical means of exposing services inside a local network to the public internet. A relay server with a public IP establishes a tunnel that forwards public requests to hosts on the internal network. It is commonly used when a local development environment needs to be accessed from outside.
Core Facts
When using Dify's online page to access a local database or local environment, it is necessary to expose the local machine's IP to the public network through an intranet tunneling tool.
Intranet tunneling refers to using a third-party server to map services within a local area network to a publicly accessible address, with commonly used tools including frp, ngrok, and Ngrok Peanut Shell.

When using the official online version of Dify, if the AI application needs to access a local machine's database or local environment, an intranet penetration tool is needed to expose the local IP.
Deploying Dify locally with Docker allows direct access to the local machine's database and other environment resources, whereas the online version needs a tunneling tool to access local machine resources.

The video advises against using a personal computer as a server, because home broadband typically does not allow outbound services, home IPs change and disconnect, and exposing a public IP poses security risks.
Accessing a local database through the official online page requires the use of intranet penetration tools (such as frp, ngrok, or ngrok Peanut Shell); local Docker deployment is more recommended for production environments to directly access local resources.
The core principle of intranet penetration is to establish a relay node on a public server, where the local environment actively connects to the public server via a persistent connection, and external requests are forwarded to the local environment through the established connection.
