The computer center of the university has a total of 240 computer rooms, has been connected to the local area network, to access the school resources through the campus network interface, and access to external resources through the ADSL interface.
To resolve Windows XP and Windows 2003 with ADSL Broadband dialer, you can do everything with a little configuration of the Windows 2003 Routing and Remote Access program.
1, the premise of a computer (configuration is not very high, as long as you can install Windows 2003 on the line), installed with the Windows2003 operating system, plug 3 network card, network card 1: Connect the internal LAN, ip:192.168.1.1, subnet mask: 255.255.255.0, Gateway: null, DNS: null; network card 2: Connection ADSL,IP: Automatic acquisition, DNS: Automatic acquisition, network card 3: Connect Campus Network, ip:202.203.230.2, subnet mask: 255.255.255.0, Gateway: 202.203.230.1,dns:202.203.220.2 (assuming the campus network segment is between 202.203.220.0-202.203.230.0, DNS server is 202.203.220.2);
2, server Configuration Step1. Click Start-Administrative Tools-Routing and Remote Access, start the Configuration Wizard, select the local server, click Actions-Configure and Enable Routing and Remote Access (figure I). Click Next, select Custom Configuration-Next, check demand-dial connections (used by branch office routing), and LAN routing-next-finish to start Routing and Remote Access.
Figure 1
STEP2. Select "Network Interface", click Action-New demand-dial interface-Next-Next, select Use PPP on Ethernet (PPPoE) connection-next-Next, eject the protocol and security option, remove all hooks, and click Next. " Enter ADSL account number and password, "Next"-"finish".
Step3. Create a new batch of processing file Route.bat and add its shortcuts to start-Programs-Start, edit the Route.bat content as follows:
3, the client configures TCP/IP configuration as follows: ip:192.168.1.x, subnet mask: 255.255.255.0, Gateway: 192.168.1.1, preferred DNS server: Local ADSL domain name server IP (can be queried to the ADSL provider, such as Kunming Telecom is: 202.98.160.68), alternate DNS server: 202.203.220.2. The DNS settings here are critical, and some people mistakenly set DNS to: 192.168.1.1.
Third, summarize the use of this method to achieve broadband sharing, can save the cost of purchasing routers, almost no use of server resources, and as long as the server to plug the network card, you can arbitrarily expand the number of clients or external exports. My unit more than 400 computers use this method to share a 2MADSL broadband will have a year, the operation is very stable, each computer is like in the independent use of a 2MADSL in the Internet, while you can quickly browse the campus resources to achieve online office, why not!
