Immediate plug and instant use proxy gateway and method thereof

Abstract

The present invention provides a plug and play proxy gateway and its method. It can make user have no need of changing network configuration of customer machine and can access interconnected network. Said invention includes a network equipment, in said network equipment are mounted a web card and a proxy gateway execution module, said proxy gateway module includes: an ARP broadcast packet interception submodule, an ARP deception packet generation and transmitting submodule and a customer machine route list, and an ARP response packet interception submodule. Said invention also provides the concrete function and action of every above-mentioned submodule and customer machine.

Description

technical field [0001] The invention relates to an Internet access proxy gateway technology. Background technique [0002] Since my country's access to the Internet in 1994, Internet technology and applications have grown rapidly in my country from scratch. By last year, the number of Internet users in my country had jumped to the second place in the world, second only to the United States. Although experienced the dot-com bubble in 2000, Internet users did not decrease. According to the information released by China Internet Network Information Center (CNNIC) in the 11th "Statistics of Internet Development in China" survey report. As of the end of 2002, the global population using the Internet has reached 655 million people. And nearly one-third of the world's new Internet users are in developing countries. [0003] The way of surfing the Internet has also developed from dial-up to various broadband forms such as ADSL or Cable Modem and local area network (LAN) at the p...

AI Technical Summary

Problems solved by technology

[0005] From the above description, we can see that due to the technical characteristics of the ARP protocol, for existing proxy gateway products, the client computer must belong to the same network segment as the proxy gateway, otherwise the client computer will not be able to directly obtain the MAC address of the proxy gateway, thus Unable to connect to the gateway and ultimately unable to access the Internet

like figure 2 As shown, the IP addresses of client 3 and proxy gateway 2 are not in the same network segment, so the client cannot access the Internet normally

[0006] Therefore, the user needs to configure the local IP address, subnet mask, default gateway, DNS server and other related settings for the client computer according to the network environment of the local network, but this is just for mobile users, such as laptop users. Some troubles have been caused in the application, such as the user of the notebook computer must first understand the configuration of the local network from the network administrator, and then reset the notebook computer to conform to the configuration of the local network environment (unless there is a DHCP server in the local network, and many The company or place is unwilling to set up a DHCP server for some reasons or management purposes)

This kind of defect not only caused a lot of trouble to users, but also required users to have considerable knowledge of network technology, otherwise they would not know where to start when facing the above problems
