Problems solved by technology

Even if it cannot be cracked, it will affect the normal use of the network
For the situation where multiple computers or cameras are configured in the company, each camera is mapped to a different port, and each computer is also mapped to a different port, and the maximum number of ports that can be mapped by the router often used is also limited.
The mapped ports are often unstable and cannot be guaranteed to be used in time, resulting in the need to restart the router frequently

Embodiment 1

[0036] Such as figure 2 As shown in , this solution shows the network structure of using a single client to access surveillance cameras in remote offices.

[0037] The equipment in the office at the monitored end does not need any adjustment and setting, only need to directly connect the IP camera and P2P-VPN gateway and set the relevant parameters of the IP camera and P2P-VPN gateway according to the specific network environment, while the user at the monitoring end , you only need to ensure that your computer can be connected to the Internet and install and configure the client software provided with the device, then you can access the IP camera at the other end of the Internet.

[0038] Similarly, other single clients connected to the Internet can also jointly access the same network camera resource in this way.

Embodiment 2

[0040] Such as image 3 As shown, this solution shows the network structure of using multiple clients in the same local area network to access surveillance cameras in remote offices.

[0041] The configuration and settings of the devices in the office at the monitored end are the same as in Scheme 1, and multiple users at the monitoring end can access the remote network cameras (such as client 1 and client 3) by installing client software. The network camera can be accessed through the network sharing method provided by the invention without installing the client software.

Abstract

The invention relates to a remote access gateway surpassing NAT based on a P2P-VPN technology. The gate is based on the internet technology, combines embedded system application, and establishes point-to-point tunnel connection with client software which works on a terminal under the assistance of a server on a public network through a virtual VPN network technology; once the connection is established, the server on the public network does not participate in the communication between the P2P-VPN gateway and the client software, and the client software and the P2P-VPN gateway are in real P2P connection, thereby realizing the surpassing of NAT in the network and providing a bridge between remote access and control for a user, so that the user realizes the remote access of information like media and data; and compared with the prior art, the gateway has the advantages of stable performance, wide scope of adaptable networks and strong NAT surpassing capability, can realize non-computer on-duty service and can construct cross-regional internal network with low cost without the address of the public network.

Description

technical field [0001] The invention belongs to an embedded gateway device, which is an embedded VPN gateway device based on the SSL protocol. Background technique [0002] At present, the application of the network is becoming more and more popular. Not only is the network inseparable from our work, but the role of the network in our daily life is also increasing. Telecommuting extends from general remote login to the company's business computer to remote viewing of the company's cameras. Not only can you access and use your own computer in the company outside or at home, but you can also check the work in the company in real time. In the current remote access solution, the configuration of the router is modified when remote access is implemented. This is a relatively high requirement for general small and medium-sized enterprises without dedicated network management personnel. Moreover, the remote access solution configured through port mapping requires additional confi...
