Problems solved by technology

[0005] Although the IPSec channel can indeed provide security when messages and data are transmitted and circulated between gateway A and gateway B, after the packets of messages and data are sent out by the virtual private network host, the channel until it is received by gateway A Between, due to the configuration of internal network ports and virtual private network ports, such as figure 2 As shown, these messages and data packets are very likely to be captured and captured by other computers in the home network.

Embodiment Construction

[0028] Please refer to image 3 Shown is a schematic diagram of the virtual local area network architecture of the present invention. The present invention uses a network device 1 to connect multiple computer devices 2, so that a local area network can be formed between the multiple computer devices 2, and the computer device 2 can also be connected to the Internet through the network device 1, or can be connected to a remote network. 3 connect to form an IPSec channel 4 of a virtual local area network (VLAN).

[0029] Please refer to Figure 4 As shown, it is a schematic diagram of the structure of the network device of the present invention. The network device 1 of the present invention includes a virtual local area network port 10, a hardware address filter 20, a network domain address limiter 30 and a fixed dynamic host configuration protocol corresponding Table 40. The virtual local area network port 10 includes a first section and a second section, the first section i...

Abstract

This invention relates to a kind of high-security network equipment by use of IPSec. It concludes a VLAN, a MAC filter, an IP Restriction and a Static DHCP. Before enciphering the transmitted message, the VPN is isolated with common network communication. Thus, the security of IPSec is increased. It is applicable to domestic and common virtual private network.

Description

technical field [0001] The present invention relates to a network device and method for providing high security using IPSec (Internet Protocol Security, Internet Protocol Security), in particular to a method that can physically isolate a virtual private device before using IPSec to encrypt the transmitted message. The network device and its method for network and general network communication are applicable to home and virtual private networks. Background technique [0002] With the advancement of network technology and the popularization of computers, the existing communication architecture has been greatly challenged, one of which is to replace the traditional way of connecting to the network through dial-up modems or dedicated lines with a virtual private network (VPN). Users can transmit various data, audio and video messages and data between two computers through a shared or public network, just like a traditional point-to-point private network. [0003] Moreover, a vi...
