Intranet is local area network or office network established within a company or home, which can realize resource sharing between multiple computers, including equipment, information and data etc.. Extranet is connected to other network systems through a gateway. Comparing with intranet, this network system is called external network, the most common one is Internet we’re using everyday. Generally speaking,external network devices cannot access internal network devices directly if without fixed public IP. Wifi 4g router with sim card slot intranet penetration is a technology that allows users to access devices connected to wifi 4g router with sim card slot through Internet, even if these devices under the same local area network (LAN). It can communicate with devices in internal network or external network, and implement functions such as remote access and file sharing.
Intranet penetration known as NAT penetration also, main characteristics is they can access external network, but cannot be effectively accessed by external network devices. Based on this feature, NAT penetration technology allows the device behind NAT to access designated external network server first, then the designated external network server builds a bridge to open up access channels for internal and external network devices, allowing external network devices to access internal network equipment. In addition to access devices hidden behind NAT, this technology can also penetrate firewall, this is because firewall generally block inbound traffic only but not outbound traffic, so the devices within the firewall can also be allowed to provide services to outside world. Since internal network equipment is not directly connected to external network equipment, so there is no doubt about its security, internal network penetration can achieve both safety and efficiency.
Why need wifi 4g router with sim card slot intranet penetration?
Normally, wifi 4g router with sim card slot assigns a LAN IP address to the devices connected to it, these devices can communicate with each other within the LAN only but cannot be directly accessed from external network. In some cases, we may need to access the devices connected to wifi 4g router with sim card slot from external network, such as remotely logging into home computer and monitoring home camera etc., at this time wifi 4g router with sim card slot intranet penetration can come in handy, it can help us achieve these needs.
When is it necessary to use intranet penetration function?
1.Service applications need to use website port 80/443.
2.No router management rights.
3.There is no real dynamic public IP in the network.
4.The network structure is too complex or difficult to deploy.
How to achieve wifi 4g router with sim card slot intranet penetration?
There are many methods to achieve intranet penetration of wifi 4g router with sim card slot, [Quick Analysis] is a common method.

The steps to use [Quick Analysis] to achieve intranet penetration of wifi 4g router with sim card slot are as follows:
1.Download and install [Quick Analysis] client end, follow prompts to register and log in.
2.In [Quick Analysis] client end, add the devices that need to be penetrated.
3.Configure port forwarding in wifi 4g router with sim card slot and map the port of the device that needs to be penetrated to public network port assigned in the [Quick Resolution] client end.
4.Start [Quick Resolution] client end, it will automatically establish a connection with the server and generate a unique external network address.
5.In external network, communication with internal devices and remote access can be achieved by accessing the generated external network address.
Wifi 4g router with sim card slot intranet penetration is widely used in the following scenarios:
1.Server management: For servers owned by enterprises or individuals, the server can be remotely managed, configured, maintained and backed up through wifi 4g router with sim card slot intranet penetration.
2.Remote control: Some smart devices need to be controlled by mobile or computer within the LAN, we can remotely control these devices with wifi 4g router with sim card slot intranet penetration.
3.Home monitoring: Connect home surveillance camera to wifi 4g router with sim card slot, we can view home surveillance footage anytime and anywhere with intranet penetration.
4.Remote access: Through wifi 4g router with sim card slot intranet penetration, we can remotely log into the computer at home or office to obtain files and monitor computer status etc..
Wifi 4g router with sim card slot intranet penetration is a convenient and practical technology, we can easily achieve remote access, file sharing and other functions with it. Using [Quick Analysis] which is a powerful content penetration tool, can help us achieve these needs quickly and safely. Whether it is a home user or an enterprise user, intranet penetration can bring us convenience and benefits in some cases.
