No route and no server for ADSL Internet sharing

Recently, some friends have asked how to share Internet connections with multiple computers when there is no ADSL Modem with a route and they do not want their computers to be on as servers for a long time, there is a method for your reference.
More families have two or more computers. They always hope that these computers can be used independently and interconnected to share Internet resources. Many articles have introduced this method of connecting to a local area network, but most of them are fixed with a computer as a proxy server. That is to say, this computer must be enabled and connected to the internet before other computers can access the Internet, this is obviously inconvenient for a home user. Some friends, for some special reasons, do not have an ADSL Modem with a route and want to share it with others. How can this be done?
This article describes a "serverless" and router-free Internet-based ADSL Network Solution. Users can access the Internet independently on any computer in the home, or multiple computers can access the Internet at the same time. However, the required device is only a five-port or eight-port hub with less than 50 RMB) or a switch. Software Installation and network configuration are also very simple.
The basic idea of the solution is that, no matter how many computers in the family are working, the computer that first accesses the Internet will automatically assume the role of a proxy server, and other computers will be able to access the Internet directly through it, of course, this role can be converted at any time, so strictly speaking, it is not a serverless role, but anyone can be a server ). The following describes how to install the network connection and software on two computers, using ADSL Broadband Internet access, Windows XP, and systm4.5 proxy server software.
Hardware connection network connection: Filter voice splitter) and ADSL Modem are provided by the supplier, and there is a leased line connection between them. ADSL Modem RJ-45 port, through the twisted pair and eight HUB UpLink port connected when the twisted pair with crossover method, and 8th port connected,), each computer network card on the RJ-45 port, you cannot connect to any part of the HUB's 1st-7th through a twisted pair ).
Set the network for each computer. Install the ADSL virtual dialing software, such, and establish a dial-up connection, which is very familiar to ADSL users or has been completed by the supplier, so we will not detail it below); install the agent server software, such as SyGate4.5.
First, double-click the "network" icon in the "control panel" to open the "network" dialog box. On the "configuration" tab, set the "TCP/IP attribute" of the network:

"DNS configuration ":
Select "Enable DNS": "host" is set to "1" or "2"); "DNS server search order" is set to "61.134.1.4 ".
"Ip address ":
Select "specify IP Address": "ip address" is set to "192.168.0.1" or "192.168.0.2"); "subnet mask" is set to "255.255.255.0 ".
"Gateway": set to "192.168.0.2" or "192.168.0.1 ).
"61.134.1.4" is the IP address of the adsl dns server, which is provided by the supplier. For ease of memory, it is recommended that the internal IP addresses of each computer correspond to the host number. For example, the IP address of Computer 1 is set to "192.168.0.1 ", the IP address of computer 2 is set to 192.168.0.2. On the contrary, the gateway of Computer 1 should be set to 192.168.0.2, And the gateway of computer 2 should be set to 192.168.0.1.
When installing SyGate4.0 on each computer, you must select the Server mode) and use the "Configuration" in SyGate Manager) "menu to set it to assume that the computer's Nic is Realtek RTL8139 ):
"Internet access Outgoing Connection Settings )":
Single choice "Lan Etherne)" 000X: CNT PPPoE AdapterADSL virtual network adapter, X is a digital number ).
"LAN Settings Internal Network Settings )":
Select "manually Select manually)" 000X: Realtek 8139-series PCI Fast Ethernet NIC local computer NIC ).
"Dial setting Dialup Settings )":
Check "Never stop Never hang up )".
"Options )":
Check "Enable internet sharing service Auto-star internet sharing automatically )".
In this way, each computer will automatically run the SyGate software when it is started. First, the computer that uses the virtual dial-up to access the Internet will automatically assume the role of the proxy server, and the other computer will be able to access the Internet directly. If the first computer is disconnected from the Internet, and the other computer only needs to access the Internet through virtual dialing, then the first computer can access the Internet directly.
When a home has three computers interconnected, the settings are similar. All you need to change is the gateway settings: at this time, the gateway of Computer 1 should be set to "192.168.0.2" and "192.168.0.3"; the gateway of computer 2 should be set to "192.168.0.1" and "192.168.0.3 "; the gateway of computer 3 should be set to "192.168.0.1" and "192.168.0.2 ". Of course, more than three computers can be easily followed.
If you are not using ADSL, but other broadband networks, the network connection and configuration methods are basically the same, but the access is not a telephone line, but a pair of wires, of course, the "filter" and "ADSL Modem" devices are no longer required, and virtual dialing software is no longer required.
When the ADSL Broadband Network is selected, the telephone interface 1 is connected to the listen 11 line of the filter, and the listen 11 line of the filter is connected to call interface 2. There is no signal on the inbound network, network interface 1 is empty, network interface 2 and 3 are connected to any two of the 1st-7th ports of the HUB respectively, network interfaces 4 and 5 are connected to the NICS of computer 2 and 3 respectively.
If you select another broadband network, you only need to connect call interface 1 to call interface 2. Network Interface 1 connects eight HUB UpLink ports or 8th ports), network interface 2 and 3 connect any two of the 1st-7th ports of the HUB, respectively, network interfaces 4 and 5 are connected to the NICS of computer 2 and 3 respectively.
This networking solution is very convenient to use. Any computer in the home can directly access the Internet at any time, or use the virtual dialing ADSL method ). Of course, the power supply of ADSL Modem and HUB must be always on.
The above methods all occupy some computer resources. If it is China Telecom bound to the MAC address of the NIC, this method may not work, but it is only suitable for friends who need it and do not have ample conditions. However, vro devices and ADSL Modem with routes are getting cheaper and cheaper ~ $250, with route Modem250 ~ 300 RMB), and the performance is getting better and better. In particular, the ADSL Modem bridge router is much more stable than the vast majority of Modem with routes, so when conditions permit, I suggest you configure the above devices.
