DIY simple Router

1. About vrouters

Router Route) is a system responsible for path finding. In the Interconnect Network, you can find the network path with the least amount of communication from multiple paths. It uses the path finding protocol to obtain network information, and uses the path Finding Algorithm and criterion based on the "path finding matrix" to select the optimal path. According to the OSI reference model, a router is a network-layer system. Routers are divided into single-Protocol routers and multi-protocol routers.

Assume that CIDR Block 1 "192.168.1.n" is connected to HUB1) and CIDR Block 2 "192.168.2.n" is connected to HUB2, the two hubs are directly connected to each other. Currently, the two CIDR blocks must be pinged to each other and communicate with each other through "Network neighbors.

Because of the high price of the router, you can use the "routing and dial-up connection" service provided by Win2K to use two network cards to implement the NIC routing function!

2. network hardware connection

1) Make sure that the computers in the "192.168.1.n" network segment are connected to HUB1; the computers in the "192.168.2.n" network segment are connected to HUB2. Then, use a twisted pair wire to connect HUB1 and HUB2.

2) Make sure that two NICs are installed on the Win2K server, connect HUB1 and nic 1 with twisted pair wires. Use another twisted pair to connect HUB2 and nic 2 with another Nic) connect.

3. TCP/IP attribute settings

1) on the Win2K server, open "network and dial-up connections" in the control panel. If both NICs are successfully installed, you can see two "local connections ". Then, right-click Nic 1 and select "properties" to open the properties setting window for the local connection.

2) Next, go to the "General" item in the local connection property settings window, and double-click "Internet protocol TCP/IP" in its component list) "to enter the TCP/IP property settings window.

3) Next, select "Use the following IP Address" in the TCP/IP property settings window, and then enter "192.168.1.1" in its "IP address ", the "subnet mask" is "255.255.255.0", and other items do not need to be filled in. Just "OK.

4) after the above steps, the Network Card 1 is bound to the IP address "192.168.1.1". It will also be the default gateway address of the Network Segment 1 client.

5) in the same way, bind Network Card 2 to the IP address "192.168.2.1". It will also be the default gateway address of the Network Segment 2 client.

6) configure all clients again, set the default gateway address and the default DNS server address to the IP address bound to the Win2K Nic In the corresponding segment.

4. Configure the Win2K Router

1) on the Win2K server, select "Programs> Management Tools> routes and remote access" from the Start menu to enter the main Configuration window of the vro. However, by default, "server status" will be "Not Configured ".

2) Right-click the "SERVER" name in the "Tree" column on the left of the Main Window and select "configure and enable Routing and Remote Access" to open the Installation Wizard for this service.

3) In the Installation Wizard, when "public settings" appears, click "network router" and then "Next ".

4) Next, you will need to select the Protocol required for the route. In this case, at least "TCP/IP" should be available in the protocol list box. Click "yes, all available protocols are listed and "Next" continues.

5) at this time, the system asked: "Do you want to access the remote network by requesting dial-up? "Because you do not need to dial up to access the remote network, you can click" No "and then" Next "to complete the configuration of the vro! In the main window of "Routing and Remote Access", you can see that related operations have been completed.

6) You can use the NIC routing function without restarting the computer!

5. actual connection results

1) any computer in any network segment can Ping the IP addresses of all computers including this network segment, another network segment, and Win2K server!

2) Open the "Network neighbors" of any computer. You can also see that the names of all computers have been added to the list! Double-click the computer name to access the shared resources.
