How to implement communication between China Telecom and China Netcom through dual-WAN router

At present, the router industry is developing at a high speed. At this stage, the routing technology is very mature. Next we will mainly explain how to use dual-WAN Port Routers to achieve communication between China Netcom and China Telecom. Currently, China's ISP service providers mainly include China Telecom and China Netcom. The bandwidth between China Telecom and China Netcom is low, leading to many problems. This problem has an impact on the Information Communication of enterprises.

There are many logistics/distribution companies in the country. Due to the differences between ISPs in the South and the North, users in the North cannot access the websites of the South branches and exchange data. At the same time, because different ISPs are used in the southern and northern branches, the enterprise's internal ERP system is difficult to use or even unavailable. To solve this problem, the common practice is to use WAN port router devices in dual-WAN Port Routers. The dual-WAN Port Routers are built with China Telecom and China Netcom routes. By applying for one line of China Telecom and then setting "China Telecom goes through China Telecom, with Netcom, the local PC can efficiently access the sites of China Telecom and China Netcom. In combination with the built-in VPN function, VPN can be used to dial the user's telecom to China Telecom and China Netcom to go through China Telecom.

In this way, the Vigor router builds a highway between China Telecom and China Netcom. The Netcom user accesses the Netcom line of the central router at high speed through the Netcom line, and then the request is sent to the telecom line within the central router to reach the destination telecommunications site. Then return the data according to the original path. As a result, the conversion between China Telecom and China Netcom is carried out in the router LAN, so there is no speed bottleneck, thus solving the problem of slow speed between China Telecom and China Netcom. There are also many manufacturers of Dual-WAN port router equipment. After purchasing the equipment, the application of dual-WAN port router equipment has received much attention. The following describes how to set up a WAN port router to achieve fast access between China Telecom and China Netcom.

We will take the Vigor2910/2950 in huagai as an example to introduce how to set up fast access between China Telecom and China Netcom. There are two situations: one is that single-node Internet access requires "China Telecom, China Netcom", and the other is that multiple computers require "China Telecom, China Telecom, china Netcom is connected to China Netcom. Pivot single-host internet access/Single-host require "China Telecom, China Netcom". In this case, a single-host is transferred to the dual-WAN port router VPN, and then the "China Telecom, China Netcom, China Netcom" is implemented through the central router ".

Steps for setting the server:

1. Set China Telecom to China Telecom and China Netcom to China Netcom. Assume that wan1 is a China Telecom line and wan2 is a China Netcom line, as shown in figure

2. Set the VPN dial-in file:

Client setting steps:

1. Run SmartVPNclient

2. Click "insert" to edit the configuration file, as shown in. Note: When entering the VPN Server IP address, you must fill in the IP address of the WAN port corresponding to the dual-WAN port router at the center end based on the line you are using. For example, the IP address of the China Netcom line is allocated to the WAN2 China Netcom line of the central router when VPN is set.

After the dial-up is successful, the pivot PC is connected to the central network. Because the "change default route to this VPN tunnel" option is selected, all the Internet data will be transferred through the central router, in this way, "China Telecom and China Netcom go through China Telecom" is realized ". Then visit the telecom site and you will find that the speed is much faster. If there are a large number of branches and all PCs require "China Telecom and China Netcom", the single-host dialing mentioned above is not suitable, it is very troublesome to dial each machine separately, and the management of network administrators will be more complicated. In this case, it is much easier to use a dual-WAN router with a built-in VPN and a central router connection on the client.
