Shulou(Shulou.com)06/02 Report--

# recently I have been writing about this switch of Cisco and Huawei. Let's talk about enterprise class, Internet cafes, routers for small and medium-sized enterprises, web type (network management type).

# what is a multi-wan router used for?

# to give a simple example: if an enterprise business is more important, in order to prevent a single line failure, it may pull another line, that is, it can play the role of backup and load balancing.

# in fact, pull two lines, one is for telecommunications, one is for mobile / / or a dedicated line, and the other is adsl / / for uploading and downloading at the same speed, but the upload and download speeds for adsl are not the same-remember

# that is, when the external network (telecommunications is down), you can move, when the external network (mobile) is cut off, you can go to telecom

In fact, multi-wan routers often use shunting.

# what is diversion

# from the literal understanding is the trend of traffic, let me give a list of Internet cafes for example, I can use wan1 port to play games, wan2 port to go video, download / / this is streaming

# next, briefly introduce the configuration of the router.

# when configuring a router, the router will have an ip address by default, either 192.168.1.1 or 192.168.0.1 or something else

# next is the connection of the line

Wan port connects to the external network

The lan port is connected to the intranet, and the lan port cable is connected to the network card of the PC.

Then set the local connection of the PC and the ip address of the same network segment. For example, if the ip address of the router is 192.168.1.1, then the ip address of the computer can be set to the same network segment: 192.168.1.2.

Or set the local connection to obtain automatically. It will automatically obtain an ip address of the same network segment as the router. / / because in general, the router will enable the dhcp function by default.

# configure the router: enter 192.168.0.1 (router ip address) in the browser address bar: as shown below

# next go to the login page of the router:

Enter the user name password / / root default is the user name, the password can be set by yourself, but you must remember it

# enter the main configuration interface of the router

# as can be seen from the above figure, this router has four wan ports, which means that the external network can be configured with up to four lines

Look at the menu on the left: configuration wizard: general rookies had better use the configuration wizard to configure, so it is easy to succeed, and you can configure it manually when you understand the principle.

# then select interface 1, and click Yes

Enter Wankou configuration: as shown below:

# as shown in the agreement above, there are three aspects: pppoe / / this general household, adsl

Static: / / static ip address: this is usually a dedicated line, that is, China Telecom gives you an ip address, subnet mask and gateway.

Dhcp:// dynamically acquires the ip address, which is generally used for the connection between two routers

Line bandwidth: the number of megabytes / / total bandwidth pulled

# Network configuration below

As shown in the following figure:

# as shown in the figure above, multiple wan ports can be configured

# next, configure the private network ip address, as shown below:

# dhcp is not set in the figure above, because this is an Internet cafe router. Internet cafes generally use diskless servers to configure Ip addresses for clients, so dhcp is not set on the router.

# next, set intelligent traffic control, as shown in the following figure:

Turn on intelligent flow control: generally, there is an application priority. If the priority is 1, the first priority is the first one, and so on.

If you turn on intelligent flow control, he will distribute the bandwidth evenly, no matter how many people you have on the Internet, it is the same when there are many people, and it is the same when there are few people.

# Video streaming is shown below:

# that is, under multiple external network lines, let another line specifically use video, so as to play a diversion role

# the following are the advanced settings of the router: for example, port mapping, vpn

Let me briefly talk about port mapping.

# that is, I have a host in my internal network, and now I need the external network to be able to access it, so I need to use port mapping, that is, when accessing the ip address of the external network, I map it through the port number, and then access the host in the internal network.

For example:

Public network ip address port number private network ip address port number

100.1.1.1 8080 1 92.168.1.2 80

# above are port mappings. You can access the ip address of the private network by accessing http://100.1.1.1:80.

# Let's take a look at private network monitoring.

# the above pictures can accurately see the network usage of each host

# finally, there is a backup of the router and a firmware upgrade

# to sum up, it is based on the comparison of Huawei and Cisco, that is, the graphical interface is more friendly, in fact, the principle is the same. Huawei and Cisco can match it, and it is much easier to configure such a router.
