Measure the test taker's knowledge about some ancillary functions of vro settings.

Before learning about vro settings, let's take a look at the running status and Configuration Wizard in configuration mode, and then introduce the DHCP server. After the popularity of ADSL Broadband Services, almost all households have installed Broadband, and families with multiple computers have to purchase routers to share the network. There are more and more types and models of home broadband routers on the market. Consumers will consider the price, performance, and appearance when purchasing vrouters. For this reason, the manufacturers have racked their brains to add various features to their products, constantly changing the shape.

If you have already purchased a vro, can you understand the features attached to it and how to use them. Maybe you want to use some of its functions, but you don't know how to use it. Then let netman answer your questions and learn what vrouters can do. As a home-level router, its main function is network sharing, so that multiple computers can access the Internet at the same time. Other functions can be used as auxiliary applications to help users make more advanced configurations.

Net Xia selected TP-Link company TL-R402M as an example, to explain the role and usage of these functions. It is a wired router and covers most of the common functional modules of home routers. Other brands and models of routers can follow this type of push. After logging on to the vro Management page, set the network router. The left-side menu bar contains the following menus: running status, Configuration Wizard, network parameters, DHCP server, forwarding rules, security configuration, routing functions, and system tools. You can configure a project.

I. Running status

Select the running status to view the current status information of the network router settings, including the LAN port status, WAN port status, and WAN port traffic statistics.

Ii. Configuration Wizard

This option can guide you through some basic configurations to ensure normal broadband connection. For example, enter the bandwidth account and password. This option is suitable for users who do not manually modify parameters. We will not explain it too much.

Iii. Network Parameters

1. LAN port configuration. The LAN port configuration option is used to modify the IP address of the router. When you set a vro, the entered address is a number in the "ip address" field. The "subnet mask" item does not need to be modified in general. If you change the local IP address, you must use a new IP address to log on to the WEB management interface of the router. The default gateway of all computers in the LAN must be configured with this IP address to access the Internet normally.

2. for WAN port configuration, the broadband services provided by ISP service providers are generally PPPoE. For common users, you only need to select PPPoE In the WAN port connection type, and then enter the Internet account and password provided by ISP service providers, click Connect to access the Internet. You can select the connection mode as needed. If you choose to manually connect, You need to log on to the vro every time after the vro restarts and click the connect button to access the Internet.

3. Clone the MAC address. You can clone the MAC address of the current management PC to the "MAC address" column. If your ISP requires MAC address cloning when providing services, you can perform this operation. Otherwise, do not clone the MAC address.

Iv. DHCP server

1. It is not easy for users to Configure TCP/IP protocol parameters for all computers in the LAN. The DHCP server can automatically assign IP addresses to computers in the LAN. After this function is enabled, select "automatically obtain IP Address" in the configuration item of the Computer Nic, And the DHCP server will automatically assign an IP address to the computer. After the computer restarts, it will obtain a new IP address, which may be the same or different from the previous one.

Address pool: the start address and end address when the DHCP server automatically assigns an IP address. After the two IP addresses are configured, the IP address of the Intranet host is located between the two addresses. Gateway: Enter the IP address of the LAN port of the router. The default value is 192.168.1.1. DNS server: These two items are optional. You can enter a public address or get them from the ISP service provider. This function takes effect only after the vro is restarted.

2. In the client list, you can view information about all hosts that obtain IP addresses through the DHCP server. Click the refresh button to update the table information.

3. Static Address allocation. The static address allocation function allows you to reserve static IP addresses for computers with specified MAC addresses. When the computer requests an IP address from the DHCP server, the DHCP server assigns it an IP address reserved in the table.

5. Forwarding rules

1. Virtual Server. This option enables users on the Internet to log on directly to a server inside and outside. By default, all computers in the LAN cannot be seen by the outside world. If you want computers in the LAN to be visible on the wide area network, you can use a virtual server to define a service port. All Internet service requests for this port will be sent to the server in the LAN specified by the router, in this way, Internet users can successfully access the servers in the LAN, regardless of whether the servers are on the Internet or intranet. Example 1: If you want a WAN user to access your FTP server through port 21, the IP address of the FTP server in the LAN is 192.168.1.100, and the protocol is set to TCP, you can perform the following steps:
Step 1: click the "frequently used service port" drop-down menu on the interface to find the FTP service and its port.
Step 2: Select "FTP (21)", configure the entry ID serial number "1", and then click the button.
Step 3: on the right of the entry table, set the IP address to "192.168.1.100", select the protocol type "TCP", and enable the entry.
Step 4: Click Save.

If you want a WAN user to access your Web server through port 80, the IP address of the Web server in the LAN is 192.168.1.101, and the protocol is set to ALL, you can configure the following steps: Step 1: configure the service port.
Step 2: Enter the IP address "192.168.1.101 ".
Step 3: select the Protocol "ALL" and enable this entry.
Step 4: Click Save. If a virtual server with the Service port 80 is configured, you must set the Security Configuration → WEB Management port of remote WEB management to a value other than 80. Otherwise, a conflict will occur.

2. special applications. Some applications require multiple connections, such as Internet games, video conferences, and online calls. Because of the existence of firewalls, these programs cannot work under basic NAT routers. However, network router settings must be applied in special applications so that some such applications can work under the NAT router. When an application initiates a connection to the trigger port, all corresponding open ports will be opened for later connection and service provision.

The trigger port is the port on which the application initiates a connection. Only when a connection is initiated on this port can all ports in the open port be opened. Otherwise, the open port will not be opened. Open Port: when a connection is successfully initiated to the trigger port, the corresponding open port is opened, and the application can initiate a subsequent connection to the open port. You can enter one or more ports or port segments. Select ALL for the departure protocol and open protocol.

3. After the DMZ host is configured in the LAN, the host will be completely exposed to the WAN, which can bypass firewall blocking for Bidirectional unrestricted communication. You only need to enter the IP address of the computer to be specified, select enable and click Save. Because the DMZ host bypasses firewall protection, it is vulnerable to attacks by others on the Internet. Therefore, use it with caution.

4. UPnP configuration. This option can help the host request the router to execute specific port conversion, so that the external host can access resources on the internal host as needed. Common users do not need to adjust this option.
