Because the IP address of the public network obtained by the router will change frequently, it is impossible for us to always check the current IP address of the public network and then tell people in the external network to visit it. The function of peanut shell is to update IP in real time. When we register a peanut shell account, the system will give us a second-level domain name to use. As long as there is a domain name in the account, the domain name will automatically point to the updated IP address, so no matter how the IP changes, the domain name can always be resolved to the correct IP address. This is the advantage of peanut shells. The external network can use the domain name and the corresponding port to access the server that queries the internal network.

Here, it is emphasized that peanut shell supports multiple login methods, including:

Client for PC: supports Windows and Linux systems.

The peanut shell function embedded in the router: Netware, TP-link, Huawei, ZTE, 360 Routing, Tengda, D-link, Xiaomi, Polar Routing and many other brands.

Peanut shells implanted with NAS: Qunhui, Weili Unicom, Tieweima, etc.

Industrial equipment: micro-control industry

Hardware equipment: Peanut sticks and peanut stick Pro are their own products.

There is no public network IP and port mapping authority, and access is achieved through internal network penetration in peanut shell.

There is no public IP, or the cat's port mapping function has been castrated, so it has no right to log in to the cat and cannot be cracked. What should I do? In view of this, peanut shell also has an intranet penetration version, which can easily access the intranet through port mapping.

Let's take a look at the detailed steps. Take the IP of the server intranet as192.168.1.100 and map port 3389 as an example:

1. Open the remote desktop on the server, and confirm that other machines in the local area network can be connected through the IP of the server.

2. Log in to the peanut shell software and pay attention to opening the intranet penetration function. Then click the intranet penetration to jump to the webpage, and you can set the mapping.

Then click Add Mapping.

On the page, you will be asked to select the mapping type: custom port, then select the corresponding domain name, fill in the IP address and port number of the server, and select the temporary port of the external network port.

After clicking OK, an external network access address in the format of domain name plus 5-digit random port will be generated. Here to explain, this random port can not be artificially interfered, and the system automatically allocates it. Inquiring about the IP that this domain name points to is not the IP we are currently accessing on the network, but the IP address of the peanut shell transit server.

3. External network test access.

Find a computer in the external network, open the window of the remote desktop, enter the address just mapped, test access, and connect successfully.
