In our daily work and life, we often need to access internal network resources from external networks, such as telecommuting, remote control and so on. Exposing the internal network resources to the external network is a relatively complex process, which needs to go through a series of settings and configuration. In this article, we will provide you with a simple but effective way to build an environment in which the external network accesses the internal network.

Construction method of access to internal network through external network

Step 1: get the public network IP address

First, we need to obtain the public network IP address of the host used to access the private network. The public network IP is an IP address that can be accessed directly in the network, which can be obtained by applying to the network service provider (ISP) or looking at it in the router. Make a note of this IP address, which we will use in the next steps.

Step 2: configure private network hosts

In this step, we need to configure the hosts used to provide services in the intranet. In most cases, we need to set up port mapping or virtual private network (VPN) to achieve the function of external network accessing internal network.

1. Port mapping

In the router, find the port mapping or NAT setting and add a new rule.

Assign the IP address and port number of the intranet host as required, and specify the port number for external access.

Save settings and apply changes.

two。 Virtual private network (VPN)

Install and configure the VPN server software on the intranet host.

By setting parameters for the VPN server, an internal pool of IP addresses is assigned to external visitors.

Start the VPN server and ensure that the host on the internal network can be accessed by the external network.

Step 3: firewall and security settings

In order to ensure the security of the external network accessing the internal network, we need to do some firewalls and security settings.

1. Private network host firewall settings

Open the firewall software on the intranet host.

Allow access to the appropriate port from the external network.

For non-essential ports, it is recommended to turn off or restrict access.

two。 Router Firewall Settings

Open the management interface of the router.

Configure the firewall rules of the router to allow only the necessary ports to pass through and prohibit other unauthorized access.

3. VPN server security settings

Configure the security parameters of the VPN server, such as using a password, handshake protocol, or certificate to secure the connection.

Step 4: test the access of the public network to the internal network

After completing the previous configuration, we can use the following steps to test whether the public network accesses the private network successfully.

1. Connect to the Internet using an external network, such as a mobile phone or other network environment.

two。 Open a browser or other application and enter the public network IP address into the URL or target server address bar.

3. If all goes well, you should be able to access the services or resources provided on the intranet host.

Note:

Make sure your Internet service provider allows access to the public network IP address.

When configuring firewall rules, open only the necessary ports and close unnecessary ports to increase network security.

In the case of using VPN, make sure that your VPN server and client have security measures in place.

Through the above steps, you can easily build an environment in which the external network accesses the internal network. Remember to pay attention to the network and security settings during the setup process to ensure that your intranet resources can be safely accessed by the external network.

Recommendation of external network access intranet software

If you want the external network to access the internal network, it is recommended to use peanut shell professional software to achieve internal network penetration. Peanut shell network penetration tool, its operation is simple, easy to apply, can provide people with high-quality access services, its port mapping function is also very powerful. Peanut shell mapping effect is good, can break through the limitations of internal and external network, support any port (including port 80), and easily solve the port problem.

How to operate peanut shell software?

1. After downloading the new peanut shell, enter the user name and password to log in.

two。 Double-click the domain name you want to map, enter the peanut shell port mapping add interface, and click to open the intranet mapping.

3. The application name can be easily filled in. The intranet host is the IP address of the computer you want to be accessed by the public network, and the intranet port is the port you want to be mapped.

4. Now a mapping record will be added to the port mapping window. At this time, the public network can access the private network host by using the domain name + port assigned by the peanut shell. Generally speaking, the peanut shell can make the device on the intranet or without a fixed / public network IP, and it can also be easily accessed through the public network.

It can be seen that it is more simple and convenient to use peanut shells to access the intranet server. Peanut shell is an intranet penetration and dynamic domain name resolution software, which can realize remote access and management of home or company servers through fixed domain names. Using peanut shells, users can build a variety of services according to their own needs. Different from the traditional port mapping, the peanut shell port mapping forwards data through the forwarding server, so the speed depends entirely on the network line of the forwarding server and the bandwidth provided. This makes it faster and more reliable to access intranet servers.
