There are many ways to achieve shared broadband Internet access, and for ADSL. Most of the route functions that open ADSL Modem implement wideband sharing. For some cell broadband, it is generally used to use a specialized computer as a server or use a broadband router, but purchase a broadband router separately a small expense. There are many self-made software broadband routers on the Internet, which is more common, and the configuration is relatively simple, but this thing is now no free, each router's software registration fee is $ 36. Have you had a free software for software? After some search, there are many similar software, such as a show, online god cattle, FD Linux, LRP (Linux Router Project Linux routing), FLI4L, FREECSO, COYOTE Linux, etc., these things have a common feature, all It is Linux that can be run on a floppy disk. Among them, I think it is best to use non-COYOTE Linux, which provides a wizard program running in Windows, according to prompts, 6 steps can be successful. The following will take it as an example, talk about how to make your own software broadband router.
First see which features it have, now you can download to the Linux version and Windows version of the production process from [URL] http://www.coyotelinux.com, I chose the Windows version, with a size of 3.04m, for already With a broadband, this is nothing. The following instructions are all taken as an example.
1, support DHCP connection mode;
2, support static IP address connection;
3. Support MODEM dial mode;
4, support ISDN;
5, support PPPoE, which is the connection method of ADSL;
6, program built-in DHCP server function;
7, firewall;
8, IP automatic forwarding;
9, remote management, etc.
Our broadband is FTTB LAN, which automatically obtains an IP address. It seems that its function is in line with my request.
& Since it is a software router, you need a PC, and more than 386 matches meet the requirements. I am from others, please eat a meal, take a Pentium 75 machine, 32M memory, hard disk, optical drive, sound card, etc., the display and keyboard is only used when commissioning, bought two 8139 NIC. Hardware is ready.
To http://www.coyotelinux.com, download the required program, name called COYOTELINUX Windows Wizard, unzipped, run COYOTE.EXE, the Wizard, click Continue to enter STEP 1.
Step 1. Set the IP address and subnet mask in the intranet in the intranet, in general, without changing, directly next.
Step 2, this step may be useful for users of Cable Modem, in general, directly NEXT.
Step 3, the key step, according to your online mode, I am fttb lan, I chose "DHCP Assinged Address", ADSL's Select "PPPoE Configured Internet", fill in your username, password (two times ), DNS server address. The selection of the special line "Use a static ip configuration", fill in your IP address, subnet mask, gateway address, and DNS server address. Phone Dial Method Select "PPP Modem Dialup" to fill in the username, phone number, password, MODE, the device name, DNS server address. It should be noted that this program currently only supports hard cats. After everything is set, then the fourth step. STEP 4, the program asks if you turn on the built-in DHCP function. It is recommended to open, open this feature, the computer can be set to automatically obtain the IP address, the DHCP server can automatically assign IP addresses, DNS server addresses, gateway addresses, and save troubles for each machine. As long as the NIC driver is installed, you can go online, it is very convenient. Of course, if your LAN has been configured, you may not start the built-in DHCP server, but the IP address of the network computer must be set in the same network segment in the router. For example, the IP address of the router is 192.168.0.1, the subnet mask is 255.255.255.0, then the IP address of the other computer host must be 192.168.0.x, where x is 2 to 254, the subnet mask is 255.255.255.0, the default gateway is the IP address of the router.
Step 5, the most critical step, select your network card type. My 8139 PCI interface network card, directly supported, IO address and IRQ do not need to be set, directly next, if you use ISA network card, then you have to fill it.
Step 6, the exciting moment is here, the program requires you to put a formatted floppy disk, click "CREATE DISK", with the snoring of the floppy drive, belongs to your own COYOTE Linux router floppy disk.
Start the router, use the ping command to test whether the network is connected to the router.
The method is ping 192.168.0.1, if you can ping the router, you will indicate that the network is running normally. Otherwise, it may be that the NIC has not been set yet. It should be noted that if the router uses two identical network cards, the first block detected the network card must connect the intranet
After a period of use, the personal feeling of the computer is very stable, and the speed of browsing the web is also very fast. This router is also very stable. Because only the motherboard, the NIC has some related equipment to work, so the power consumption is very low. I saw a message on the Internet. Some people make this router to boot up to 445 days. There is no problem, and a friend of my friend has previously used Windows 2000 Server Sygate. Restart every day. I saw that the COYOTE Linux router I did so well. After going back, I immediately changed the sygate, not only saved a server, but the network efficiency increased.
