With the popularity of computer networks and information technology, many units have multiple computers, and use a telephone line or broadband sharing Internet to become a matter of current majority units for easy management and cost savings. Sygate Home Network Software is a famous Sygate Technology Company (formerly Sybergen Network), which has a gateway-type proxy server software developed by family and small and medium-sized units. It has easy-to-use security, convenient management, no need for client software. A complete solution is proposed for the unit sharing Internet access for the software version 4.0. First, Sygate software installation requirements hardware requirements: CPU 486 or more, more than 32M, hard disk space 10M, Ethernet card, MODEM (ISDN, DSL, Cable, Satellite). Operating system requirements: Win95 (MS DUN 1.3 or more), WIN98 / ME / 2000, WIN NT (Server Pack4 or more), make sure you can connect directly to the Internet. Second, the construction of the internal local area network, establish a small Ethernet area network, the line type uses UTP or COAX, and the workstation is greater than two must use Hub / Switch devices. Due to the 10BASE-2 coaxial cable, it has been rarely used. The following mainly introduces the use of twisted pair connections: 1 The two computers are first confirmed that both computers have been installed, and the current use is 10 / 100m. Adaptive network card, plug it on the PCI slot of the computer motherboard, and install the driver, then use the super five twisted pair to make a cross-line connection network card with the following method: eight in the twisted pair One end of the thin line according to orange white, orange, green white, blue, blue white, green, brown white, brown, blue, the other end according to green white, green, orange white, blue, blue white, orange, brown white, brown album, Card on the RJ-45 crystal head. 2 Multiple computers first confirm that each computer has installed a network card, and a Hub (hub) or Switch (switch) is ready, it is recommended to use 10 / 100m Hub, then make through the straight-through twisted pair to make each The computer is connected to the HUB: both ends of the twisted pair are arranged in the order of orange, orange, green, blue, blue, green, brown, brown. 2. Configuration and Test Network will prepare a computer that installs the Sygate Home Network software as a proxy server (the computer is temporarily called No. 1), selecting the network from the control panel to start setting the IP address of the No. 1. As shown in Figure 1: The IP address is set to 192.168.0.1 subnet mask is 255.255.255.0; (Figure 2) (Figure 2) The IP address of other computers is set to 192.168.0.2, 192.168.0.3 Wait, the subnet mask is equal. Use the ping command to test whether the No. 1 machine is connected to other computers. For example: performing ping 192.168.0.2 on the 1st.
Correct Unicom's return reminder as follows: pinging 192.168.0.2 with 32 bytes of data: reply from 192.168.0.2: bytes = 32 TIME <10ms TTL = 252 reply from 192.168.0.2: Bytes = 32 TIME <10MS TTL = 252 reply from 192.168 .0.2: bytes = 32 TIME <10MS TTL = 252 reply from 192.168.0.2: bytes = 32 TIME <10ms TTL = 252 three, external network construction configuration 1, dual nic (network interface card) Internet sharing 1 sharing telephone online Install the Modem (modem) on the 1st, most of the market is built-in MODEM, put it on the PCI slot of the motherboard, and install the driver, and determine the No. 1 machine can be accessed normally. 2 Sharing broadband Internet access on the 1st machine, install a network card, make the No. 1 machine a dual network machine, and connect the newly installed NIC directly on the broadband network (ADSL, CABLE, etc., new ISDN devices do not need to be installed again) Adapter card, directly connected to the No. 1 motor port), install the driver or dedicated dial program, determine that the No. 1 machine can access the Internet. The schematic is as follows: (Fig. 3) 3 Sharing an internal network connection is basically the same as the above figure, the difference is that the network card 1 directly connects the internal network, and the IP address needs to be specified as an internal network fixed address. 2. Single NIC (Network Interface Card) Internet Share Sygate Software uses a virtual NIC technology that allows the agent service computer to install only one network card to complete the shared Internet function. The network card of the No. 1 is connected to the ADSL or Cable Modem, and the virtual network card is responsible for connecting other computers in the LAN. The schematic is as follows: (Figure 4) Single NIC Internet Sharing Basic Steps: ◆ First Connect the No. 1 Machine Network to the Broadband MODEM, install the connection between the corresponding access program and the Internet; ◆ Between the No. 1 network card and broadband MODEM The strand is changed on the hub; ◆ Connect the broadband MODEM and other computers to the HUB through twisted pair; ◆ Access the Internet from No. 1 machine (please ensure that the No. 1 machine can be accessed normally by broadband); ◆ Run the Sygate self-extracting file on the 1st, then run the SHN40.exe file to start installation; ◆ Sygate will detect dynamic Internet join, and create a virtual network card 192.168.0.1 (this address can be in Sygate) Modify in the manager). Fourth, Sygate Home Network Installation Steps: Step 1 Connect all the computers above and configure the IP address, Unicom No. 1 and Internet; Step 2: 1. Run the SygatehWork4.0 self-extracting file, then run within SHN40.EXE file, enter the installation interface, all the way to the following interface: (Figure 5) 2, select Server Mode, OK; 3, Sygate automatically detect network connections, installation is completed.
Step 3: Register (Figure 6): (Figure 6) Enter the purchased serial number and registration code in the previous interface, otherwise I am A Trial User, fill in the User Name and TRAIL KEY, respectively, TriaLUser and H1001001 Test users can only use 30 days of software. Restart 1 machine. V. Sygate Software Configuration Select Start -> Program -> Sygate-> Sygate Manager, enter the following interface: (Figure 7) Start / stop - Start and stop Sygate Internet connection sharing function; Dial / Hang-up - connection and disconnect dial Network connection; resources - Provide print and file sharing services in a computer LAN; online help - provides online help; Advanced - enables users to configure Sygate networks, control network security and management Internet access content.

Configuration interface: (Figure 9) Direct Internet / ISP Connections This option is default to auto-detect, usually detected the Internet connection mode when software installation; Dial Up indicates that the external network connection is set to dial mode; Ethernet indicates the external network. For Ethernet of the intranet, you can set the IP address of the unit (such as shared internal network, you can set the IP address of the internal network, the network card IP address). The Dialup Settings check box selection indicates that the client computer can boot the dial-up connection of the external network, which can be set in the Dialup Entry List below. Local Network Connections LAN (Introduction) Connection settings, you can choose to automatically detect or manually set. Single Nic Mode Settings Sets the single NIC sharing mode as referred to. Enable Internet Sharing AT Startup Start Internet Sharing Service at the time of software. Enable Address Server (DHCP) Enables the Sygate software dynamic host allocation protocol service that automatically assigns an IP address for clients that connect to the network. Enable Access Log Records the Access Log of the Sygate client, which is stored in the server's Sygate directory. Enable Enhanced Security Enables advanced security. Open this option prevents the Internet user from accessing the intranet, and the Sygate software will block access from the 1-1000 and 5000-65536 ports from the Internet. Click the Advanced icon to enter the Advanced Settings interface: (Figure 10) Address Server (DHCP) This setting is used to control the Enable Address Server (DHCP) option.
Use the Following Assigned IP Range If you want to restrict the Sygate DHCP service to assign an IP address range of the client computer, you can refer to the start and the last IP address and subnet mask. DNS Search ORDER This can provide some alternate DNS server IP addresses that can be filled in according to the ISP (Internet Service Providers). In case the original DNS server fails, the next set of DNS will be used. Connect Time OUT Sets the connection timeout (only for HTTP, FTP, NNTP, and Telnet connections). If an idle time exceeds the set time here, the join will be interrupted (Note: Not the interrupt external network dial-up connection, the timeout time is set in the Configuration interface). User Define MTU Size In general, the Sygate software will automatically detect the correct MTU time of the server. You can also modify it here. Permission Settings (Permissions) On Figure 8, click Permissions to press New, enter your password (initial), enter the license editor, as shown in Figure 11: (Figure 11) This editor is divided into Black List (blacklist) and WHITE List (White List) two parts (check the Activate Black / White List item) when enabled. ◆ Blacklist: Sharing some sites that network users are banned from accessing; Click Add to press New Zegings to enter Figure 12: (Figure 12) Protocol Type: Protocol Type (TCP or UDP). Internal IP Address column Enter you want to limit access Web site The intranet client address, the IP address bar is blank indicates that the rule is applied to all addresses.
