A, the classification of routers

According to the performance grade: the back plate exchange capacity of more than 40Gbps routers called high-end routers, less than 25Gbps called low-grade routers.

By structure: Routers can be divided into modular structure and non modular structure.

The modular scene structure can flexibly configure the router to meet the increasing business requirements of the enterprise, and the modularization can only provide a fixed port. In general, high-end routers are modular structures, and low-end routers are not modular.

By function: Routers can be divided into core (backbone) routers, distribution layer (enterprise) routers, and access layer (access level) routers.

By application: Routers can be divided into common routers and private routers.

Divided by the location of the network: the router is usually divided into "boundary router" and "intermediate node router" two categories. The "border router" is on the edge of the network for connections to different network routers, while the "intermediate node router" is in the middle of the network and is usually used to connect different networks and play a role as a bridge for data forwarding.

From the performance division: Routers can be divided into wire-speed routers and non-wire-speed routers. The so-called "wire-speed router" is completely available according to the transmission medium bandwidth for unobstructed transmission, basically no interruption and delay. Typically, a wire-speed router is a high-end router with very high port bandwidth and data forwarding capabilities, and can forward packets at a media rate; The low-end router is a non-line router. But some of the new broadband router also wired speed forwarding capabilities.

Second, the router's settings

1, connect the line, WAN Port network (that is, the Telecommunications Bureau to provide ADSL broadband), LAN port network that is your computer card.

2, each router has its own default IP address and can be modified, you can restore factory settings, look at the router's instructions, the general is: 192. 168. 1. 1 or 192. 168. 0. 1 or 10. 0. 0. 1

3, below we to 192. 168. 1. 1 For example, configure your computer IP to 192. 168. 1. X, the gateway and DNS point to the router, that is, 192. 168. 1. 1

4, open your computer, open the browser, in the browser address bar input http://192. 168. 1. 1/, access to the router configuration interface;

5, the router's manual to here basically has no effect, but many computers still can't surf the internet, this is mainly the MAC address of the router in mischief, we find the MAC address cloning options, select the Clone MAC address, after the Internet can be maintained. But the problem again, many routers have no MAC address cloning options, then we only use their hands to clone Oh, in the router's MAC address options directly enter the MAC address of our own computer network card can be. The way to obtain the MAC address of your computer's network card is:

Start, run, cmd into the command prompt, WIN2000/XP system ipconfig?/all, and then enter. Find a string of words Furu: 00-e8-87-23-c6-54, this is the MAC address.

Here we start setting up the router's

1, the network parameter setting

Link routers and computers, and then the router for simple settings can be online, if only a simple network sharing, as long as the basic skills of the router can do a simple setup on it. Use the Web pages provided by the router itself to manage, enter 192. 168. 1. 1. Enter my router login interface, as follows

Enter its access account and access password to enter the router's access interface. Mainly to its network parameters, DHCP server and security rules to set up the Internet can be easily.

Select the network Parameters option, and then select the LAN port parameter settings, and the following Settings screen appears. This option is primarily to set the parameters of the router.

The MAC address is the MAC address of this router to the local area network, and this value cannot be changed. The IP address is the IP address of this router to the local area network, and the default gateway for all computers in the local area network must be set to that IP address. It is important to note that if you change the IP address of the LAN port, you must use the new IP address to log on to the router for Web interface management.

And if you set a new LAN port IP address and the original LAN port IP address is not the same network segment, the router's virtual server and the DMZ host function will fail. If you want to enable these features, you need to set them again. The subnet mask is the subnet mask of this router to the local area network, typically 255. 255. 255. 0, the subnet mask for all computers in the local area network must be the same as this setting.

Select "Wan Settings" to appear the following settings screen, mainly on the way and permissions to the Internet settings.

Wan port connection type means that this router supports three kinds of commonly used internet ways, please choose according to your own situation. If your Internet access is dynamic IP, that is, you can automatically from the Network service provider (such as: China Telecom) to obtain IP address, select "Dynamic IP"; If your Internet access is static IP, that is, you have a network service provider (such as: China Telecom) to provide a fixed IP address, please select "Static IP"; If you are on the Internet in the way of ADSL virtual dialing, please select "PPPoE".???? The Internet account and the Internet password are filled in with the ISP's designated ADSL Internet account number and the ISP's designated ADSL password. If an on-demand connection is selected, the connection operation is made automatically when there is a network access request from the LAN. If the automatic disconnection wait time t is not equal to 0, the network connection is automatically disconnected when no network access traffic is detected in a continuous T-minute, protecting your Internet resources. This setting only takes effect on on-demand connections and manual connections. Manual connection refers to the user manually adsl dial-up connection after power-on. It is generally recommended to select an on-demand connection, because anyone who does not want to boot up and then do trouble dialing.???? This router also has the ability to clone MAC addresses, and MAC addresses are generally not changed. However, some ISPs may require binding to the MAC address, at which time the ISP will provide a valid MAC address to the user, you only need to be based on the value provided by the binding, but most of the ADSL do not use this feature so this is not detailed.

2. DHCP server settings

TCP/IP protocol settings include IP addresses, subnet masks, gateways, and DNS servers. It is not easy to properly configure the TCP/IP protocol for all computers in the local area network, and fortunately, the DHCP server provides this functionality. If you use the DHCP server features of this router, you can have the DHCP server automatically configure the TCP/IP protocol for each computer in your local area network. Select DHCP server to set the DHCP server functionality of the router to set the screen

The address pool start address is the starting address of the IP that the DHCP server automatically assigns. The starting address in the figure above is 192, 168, 1, 101. The address pool end address is the IP end address that is automatically assigned by the DHCP server, which is 192, 168, 1, and 199 above. Gateways are optional IP addresses that are recommended for filling in the router LAN port, which defaults to 192. 168. 1. 1. The primary DNS server is also optional to fill in the DNS server provided to you by your ISP, and it is not clear that you can ask your ISP for additional options to fill out.

Note that in order to use the DHCP server functionality of this router, the TCP/IP protocol for each computer in the local area network must be set to "Automatically obtain an IP address." This feature requires that the router be restarted to take effect.

Select the client list to display the name of the host of the local network that is currently connected through the router. The MAC address of the client host, and the IP address assigned to them, and the usage time of the remaining IP address. Because the DHCP server involves some professional computer knowledge, it is not explained in detail, but this function is very useful can save the trouble of setting IP protocol.

3, the use of feelings?

Now with simple settings, you can share the Internet via a broadband router, and you can set up the router with the Setup wizard. The router also provides detailed help documentation to help users set up the router. Routers also have a variety of other router functions, such as virtual server, DMZ host, UPnP settings, dynamic DNS and other functions. and has a wealth of firewall features, including IP address filtering, domain name filtering and MAC address filtering three kinds of filtering functions, but also through the advanced settings to prevent Dos attacks.

Here are a few of the roles:

About It's DHCP service

Open the Web management interface for the broadband router, locate the DHCP option, select Enable DHCP service, and then specify the address pool (dynamic IP range) that you want to dynamically allocate through the router.

On the client (PC) side, set up TCP/IP to automatically obtain addresses and DNS.

About its security settings

In its management interface to find security settings options, turn on the "Open Firewall" option, in general, this router's firewall mainly by the following options: Filter access port, filter MAC address, filter site address

1. Filter Access Port

The network is mainly set up according to the ports that need to be accessed by different protocols. If QQ uses is 4000 and 8000 these two terminals, we only need to shield off these two ports, can restrict the computer in the local area network to use QQ, other similar, like Telnet (), HTTP (), DNS (53) and so on

2. Filter MAC Address

I believe we all know that MAC address is equivalent to each card ID card, each address in the world is unique. By shielding the MAC address of a host network card from the router side, you can prevent it from accessing the extranet.

3. Filter website address

This feature is believed that everyone will know that the use of, input you want to filter the site address can prevent your machine access to change the site, suitable for illegal websites and yellow site filtering.

The last thing to add is that these are conventional methods that are not invulnerable and are suitable for use in the general family.
