There is a WIDOWS NT and Windows 9x, the author's unit. The internal static IP address is 120.11.0.1 to 120.11.0.30; the subnet mask is 255.255.255.0. The typing room has a computer (120.11.0.14 teenage is a machine) is also hung on the Internet, and the other computer needs (because only one module interface is not directly connected to the Internet, called B machine) and A Sharing the printer. So I designed a small peer plan, adding a network card in A and B, using twisted pair jumper technology to connect the two cards directly. In order not to conflict with the original network, I set the IP address of the new NIC card of the A machine to: 192.168.0.1, the IP address of the B-machine is set to 192.168.0.2, the mask is 255.255.255.0, and NetBUI And TCP / IP two network protocols and files and printer sharing services on the Microsoft network, and set "Allow other users to access my files and printers." After the above work is completed, the two computers are restarted, all OK, can say that it has achieved a smooth achievement. Can you then have an idea to flash? Can I access the computer resources on the 120.11.0.0 network segment through the A machine? Holding this idea, the author starts experiment. You know, people do not use some PCs that have multiple NIC before do not have a router, this is not the same as the current situation? I started looking for relevant software around, I found it, and I didn't find a useful answer. Everyone knows that NetBUI is an unfair agreement, so the problem is obvious to start with the TCP / IP protocol. Can I add a gateway to the settings of the Type B machine? The author tried to add: 120.11.0.14 on the gateway column of the B-machine TCP / IP network configuration item: 120.11.0.14. This idea is to use the A-machine dual network card, act as a routing in a line, because you can see shared resources on the 120.11.0.0 network segment in the online neighborhood, and can also see the joined 192.168 .0.0 network segment of the B machine. As a result, it is still not possible to ping the computer on the 120.11.0.0 network segment, can only ping from 192.168.0.1 and 120.11.0.14, which is the IP address of the two network cards of the A-machine. From 120.11.0.0. Ping 192.168.0.1 and 192.168.0.2 are also invented, it seems that the gateway added does not seem to have a role ... Later, the author remembered that the route was not in Windows 9x. Attention, I executed Route Print on 120.11.0.9, as shown in Example 1. Among them, the part of the underline is the IP address of the switch, and try to add 120.11.0.14 on the "gateway" column of the TCP / IP network configuration item of the test machine B (120.11.0.9). After that, Route Print is run again, and the routing table has changed, and there is more than the result of Example 1 (as shown in Example 2). However, as the result is not imagined, it is still unable to ping the word chamber B machine. By examination and analysis, the distance vectors are 1, and the network address is: 0.0.0.0.
