In the era of modern Internet, we often need to provide servers in the local area network or provide access to external networks. However, since the internal network usually uses private IP addresses, it is not visible to the external network without proper configuration and settings. This leads to intranet penetration technology, which allows us to access resources in the LAN without exposing the truth.
In this blog, I will introduce a powerful and easy-to-use intranet penetration tool: cpolar is a secure intranet penetration cloud service, which exposes the local server under the intranet to the public network through a secure tunnel . This enables public network users to access intranet services normally. Next, I will introduce the characteristics, usage and application of intranet penetration of CPolar in detail.

1. Application example of intranet penetration
- WeChat official account development, real-time breakpoint debugging WeChat messages
- Demonstrate the new website at the launch event without live deployment
- Build webhook clients, chatbots on your development machine
- Test mobile apps connected to the backend of your local development environment without deploying
- Provide a stable public network access address for devices that have been deployed in the production environment
- Run personal cloud services, AI deep learning, chatbots from your home
- Remotely control your computer at home
- Remote SSH control Raspberry Pi
2. Download and install
3. Specific use examples
1. Publish the intranet site to the public network
Method 1: Command line creation
cpolar http 要映射的端口
# 例如 我想让别人访问我8080端口的服务, cpolar http 8080
Method 2: Dashboard Publishing
At this time, port 9200 is the cpolar web UI management page, access the local port 9200 through a browser and log in through the registered account: http://localhost:9200/
2. Remotely connect to the company's intranet computer
1. First run cpolar on the computer on the internal network, and allow remote desktop access
2. View the current online tunnel list of cpolar to obtain the remote desktop TCP tunnel address
3. Use the public network tcp tunnel to connect to the remote desktop
However, the free cpolar is a random TCP address, and the public network address will change within 24 hours, so it needs to be reset every time, and the bandwidth is only 1M, which is completely sufficient for daily test development, but if you need long-term access, configure a fixed TCP tunnel address, you need to upgrade to the professional plan.
