Anyone who knows about the network knows that dual network cards can be used to share the network. That is to say, the dual network card sharing network is a solution adopted by many people. Compared with the single network card sharing scheme, the difference is mainly in hardware. The dual network card solution requires only two network cards and an ordinary network cable.
This solution utilizes the operating system's inherent soft routing or proxy server software to achieve network connection sharing. Therefore, this sharing scheme does not depend on devices with specific access methods, and is suitable for ADSL, cable, FTTB, VDSL, etc. .
Schematic:
Steps:
The following is an example of sharing Internet access with two computers:
1. Select a machine as the server. Recommended criteria: 1, the performance of this machine is relatively better; 2, the operating system of this machine is better than W2K with ICS function; 3, this machine is convenient for long-term continuous operation (such as notebooks without desktop Suitable for).
2. Install the second PCI network card and driver on the server.
3. Connect the two network cards of the server and client directly through the network cable.
4, set the properties of the newly installed network card in the server system: IP address is set to 192.168.0.1, subnet mask is 255.255.255.0, gateway and DNS can be left blank.
5, in the client system (WIN98 and above), set the IP address of the network card to 192.168.0.2, subnet mask 255.255.255.0, gateway 192.168.0.1, OK.
6. Establish an INTERNET connection (ADSL PPPOE dial-up) in the server system and set it to share this connection in its properties. If it is a wired or FTTB dial-free access method, set this share directly in the NIC property of the CABLE MODEM or incoming line.
This is the end.
Description:
1. If you are sharing more than 2 computers, just add a HUB. The other computers are connected to the HUB, the IP is set to 192.168.0.3 (4, 5...), the subnet mask is 255.255.255.0, and the gateway is 192.168.0.1.
2. In different operating systems, some detailed settings may be slightly different, but they are basically the same. If the server operating system version is too low and does not support ICS (INTERNET connection sharing), you need to install the proxy server software SYGATE or WINGATE. The specific method can find the relevant data to complete.
Advantages: Less investment, a new network card, 1 network cable. The entire cost is tens of dollars.
Disadvantages: If the server is not open, the client cannot access the Internet.
