For many services built on the intranet, how to map the intranet IP to the public network, so that the public network can easily access the built services, such as website, housekeeper, FTP, SVN, remote desktop, video surveillance, database and so on. Normal and general port mapping is a bit cumbersome, and it is simpler to map with third-party auxiliary management tools:

Peanut shell realizes internal network mapping;

The new version of peanut shell can not only achieve intranet penetration, get rid of the problem that IP and NAT forwarding can not be used without public network, but also support public network. There is no need for public IP and router port mapping.

Take building a website as an example, the operation steps are as follows:

Download the latest version of the client from Peanut Shell official website, and log in after installation;

Set the mapping on the software. Click the default domain name to create new peanut shell management;

Add mapping;

4. Click on the current host. Select the corresponding port mapping in the internal network to obtain the random port of the external network, and click OK;

5. It is mapped. After the intranet is mapped, there is no need for other settings, and the mapped domain name and the IP service link corresponding to the intranet can be directly accessed through the mapped external network address.
