This article in the D-Link broadband router di-740p model, the default management address of 192.168.0.1, management port is 8080.
The ip address of a computer and router management address set in the same network segment, for example, 192.168.0.2, 192.168.0.2 computer, open the browser in the address bar enter "http://192.168.0.1:8080" and press Enterkey user login prompt appears, enter the broadband router's manual to enter the default administrative account and password settings interface.
To enable the router to automatically dial-up, we also need to be integrated into the router ADSL account.
Click the top of the "Home" tab, then click for change "WAN", the PPP over Ethernet ADSL account settings at that place, enter your account number and password to apply for ADSL and saved settings.
Now to the "System Status" tab in the "System Information" View network status at the WAN side can clearly see the ADSL dial-up access to network information.
Have set up ADSL account, we can access through a broadband router, but in order to better manage and improve security also requires the following: Click on the "Home" tab, then select the left "DHCP", enter the DHCP serverThe ip set ip address range at the range, saved with a broadband router to automatically assign ip address function.
To prevent the chaos following bt
The default setting for all computers connected to the router are protected, that is within the network, the use of bt and other p2p software affected to some degree.We can use the "Advanced Settings" tab in the "DMZ" to set the host declaration.Here the host to set the exposure on the network, on the one hand you can use bt nothing to worry about downloading software and the establishment of iis, ftp server, etc., but it also exposed to the hackers and virus before, so the security of the computer work mustto do well.(If only to use bt and other p2p software on the host declaration, then it is very unwise, in fact, we can use the upnp function within the network can not be used to solve the problem of p2p software. Router settings screen by clicking the "Tools"tab under the "other items", then upnp is set to "Start" button.)
Broadband router setup interface into the filter label, we can report on data sources and address a variety of projects in the filter, including the ip address, url information, mac address, and area information.
Set "Activation" ip address filtering, and then enter the ip address ip address range, such as 192.168.0.111."Port Range" at the port information is in fact complete, because bt download port is 6881-6889, so we can filter here."Agreement" Select tcp, "Schedule" to set the filtering effect of the time (against time to see the actual situation.)
Services and security things correct
Exposed to the internet on computer hackers and virus attacks the computer it is possible to exploit the vulnerability, in fact, we can set a virtual server to solve this problem.
Login to broadband router interface.Select Advanced Settings screen in the virtual server tab.Activation of the virtual server settings, enter the relevant information to the virtual server.For example, we want to allow this computer 192.168.0.112 provide ftp services, but to let others get the router port protection, can only be a virtual ftp service can be.Personal ip address set to 192.168.0.112, protocol mode is tcp (ftp service uses the tcp protocol), individual port 21 (ftp uses port 21).Also in the "line up" can be set at the entry into force of the virtual service time.
tp-link router configuration guide
Basic configuration of the router to the computers to share Internet access through the router implementation, the process is relatively easy to implement; this document the following, mainly about the following sections:
1, to collect and determine the information to configure the router to prepare;
2, into the router management interface, the router configuration;
3, the configuration process simple exclusion fault location!
1, the preparatory work before the home router (if you know your connection, you can skip to 2:00)
The first is the need to make sure your "broadband access" is like?
Of course, the most simple way is to your ISP (Internet Service Provider) to make a phone consult; You can also buy a router before your network connection for quick judgments.
Common hardware connections are the following categories:
1 telephone line -> ADSL MODEM -> PC
2, twisted pair (Ethernet cable) -> Computer
3, cable TV (coax) -> Cable MODEM -> PC
4, fiber -> media converter -> Proxy Server -> PC
ADSL / VDSL PPPoE: computers running third-party dial-up software such as Enternet300 or WinXP system comes with dial-up program, fill in the ISP to provide account and password each time before the first dial-up Internet access;
Or your ADSL MODEM routing is enabled, enter the account number and password provided by ISP, dial-up actions to the MODEM to do; (such broadband access such as a typical Southern Telecom "Network Express")
Static IP: ISP gives you a fixed IP address, subnet mask, default gateway, DNS;
Dynamic IP: computer TCP / IP properties set to "automatically obtain IP address" every time you start the computer to the Internet; (typical of this broadband access such as Shenzhen, "Tianwei video")
802.1X + Static IP: ISP provides a fixed IP address, dedicated dial-up software, account number and password;
802.1X + Dynamic IP: ISP provide a dedicated dial-up software, account number and password;
WEB Certification: Prior to each access, open IE, go to the designated ISP home page, enter ISP username and password provided by certification before it can get access for other operations;
(Above in bold is your broadband access methods, access methods and hardware connection is not fixed with the)
These connections mentioned above authentication number is relatively high penetration of broadband access, of course, there will be other connections and the topology of the existence of authentication; So, when you are not sure when the broadband mode, it is best toISP Consulting: your installation of broadband access, IP address is static or dynamic?Authentication protocol used is PPPoE, 802.1X authentication, or WEB?When the above two questions have answers, can be configured on the router;
2, how to enter the router management interface?
First reference to "User Manual" icon above, will be ADSL MODEM, router, computers link up;
TL-R4XX series routers addresses the management of the factory default: IP address: 192.168. 1.1, subnet mask: 255. 255. 255. 0 (TL-R400 and TL-R400 + default management address of two:192.168. 123.254, Subnet Mask: 255.255. 255.0) with a network cable to router LAN port and PC card connection is good, because the router's Ethernet port with auto polarity reversal functionSo regardless of your cable connection or cross a straight line can be, need to ensure that the net production of solid first line of solid crystal, crystal head and copper do not rust and so on.
Computer desktop, right-click "My Network Places" and select "Properties" in the pop-up window, double-click open the "local connection" in the pop-up window, click "Properties", then look for "Internet Protocol (TCP / IP)", double-clickpop-up "Internet Protocol (TCP / IP) Properties" window;
In this window, select "Use the following IP address", and then fill in the corresponding position:
IP Address: 192. 168. 1. X (X range 2-254),
Subnet Mask: 255.255. 255.0,
Default Gateway: 192.168. 1.1, filled out after the "OK" twice to;
3, check your computer and the router can not communicate?
Can be used as way to view, open the computer's DOS interface:
"Start" -> "Programs", click on "MS-DOS" (Win98 operating system)
"Start" -> "Programs" - "Accessories", click on "Command Prompt" (Win2000/XP operating system)
First, check whether the above IP address configuration take effect?
In the DOS window type: ipconfig / all and press Enter, when you see similar to the following information, said configuration to take effect,
IP Address..................................: 192. 168. 1. 10
Subnet Mast.................................: 255. 255. 255. 0
Default Gateway..............................: 192. 168. 1. 1
The second is from the computer to the router LAN port to send data packets, data packets can not return to see?In the DOS window run:
ping 192. 168. 1. 1-t and hit enter, if there are similar,
Reply from 192. 168. 1. 1: bytes = 32 time <10ms TTL = 128 Reply from 192. 168. 1. 1: bytes = 32 time <10ms TTL = 128 Reply from 192. 168. 1. 1: bytes =32 time <10ms TTL = 128 If the carriage does not appear after the above information, does the command prompt "is not an internal command or external command, operable program or batch program", then the command input is incorrect, pleaseCheck whether the input space and the like are ignored;
4, into the router management interface;
Prompted, the computer can communicate with the router, open IE, in the address bar enter 192.168. 1.1 and press Enter, under normal circumstances there will be asked to enter a user name and password dialog box.Of course, there are exceptions: If you open the IE browser address bar enter the address Enter, pop-up "work offline" dialog box, point the "connection" small window after dialing, click the IE browser menu bar "Tools"-" Internet Options "in the pop-up dialog box, click" Connect "property page, the interface as below: for the above operation,
Into the router management interface should be said that no obstacle should be a;
5, start configuring the router;
With the beginning of the broadband access of information to prepare, configure it more convenient; just into the router management interface will pop up a map similar to the "Setup Wizard" screen, you can cancel to ignore it; into the router management interface, inthe left column in the menu bar click on "Network Parameters" -> "WAN Port Settings" to configure the router for the Internet here, the direction of the WAN port mode, this is the most critical step;
Suppose your broadband access to ADSL PPPoE, then select "WAN port connection type" to "PPPoE", fill in the "Internet Account", "Internet password", if you are a unique monthly users, and then select the connection mode as follows: "Auto Connect ", click" Save "to complete the configuration; save after" Internet password "box enter the password will be several more, which is dedicated router to do to be safe;
The left column and then you click management interface of the "running" in the run status page "WAN port property," just beginning to see the corresponding IP address of DNS servers, subnet mask, default gateway address, if the site belowgraph, it means the router is dialing process, wait until these addresses have emerged in the appropriate information, will be one of the DNS server address to the box computer "Internet Protocol (TCP / IP)" page corresponding to the location determined, the basic set to be completed, and was not hurt, then you can surf!
6, the fault conditions listed;
If you do not see any address, there are several reasons below, please rule out one by one:
1) ADSL MODEM ADSL in general there will be a light, under normal circumstances MODEM connected power and phone lines after the general laws of the lantern to the speed of blinking, blinking into the final long stop light; endless if the lights flash ahFlash is not long off, please contact and inform the ISP of your ADSL MODEM can not be synchronized with the central office switch, the ADSL / DSL long bright light conditions, is necessary;
2) Fill in the configuration process of the "Internet password" are not careful the wrong time, may wish to re-enter it again;
3) ADSL MODEM enabled the "Route Mode", you need to reset the ADSL MDOEM into "bridge mode"; how to bridge mode and reset MODEM contact the manufacturer to obtain operation; also can be judged: computer access MODEM, and in computeron dial-up, dial-up Internet connection after a successful, if this is the case, then the way that the work MODEM bridge mode, you can rule out this possibility;
4) ISP MAC address of the computer and help set the network card to the ADSL line; the solution is to use the router's "MAC address clone" feature to copy the network card's MAC address to the router's WAN port;
If the above possibilities are ruled out, ADSL PPPoE dial-up generally is not too bad, here is another two listed reasons for the failure of concern;
5) Your way is the kind of broadband access directly into the Ethernet cable, not ADSL, but also need to dial, a dial-up software is not limited to, authentication protocol used is PPPoE, it is not dial-up success; if the ISP promisesbandwidth is 10Mbps, suggested: find a 10/100M adaptive hub, the broadband into the line connected to the hub, and then link the hub to the router WAN port; through such a rate adaptation process, dial-upThere should be no problem;
6) buy a router before, you are also run through the computer dial-up software, fill in user name password for dial-up.ISP dial-up software is available, but special software, other software, dial-up can not be successful; if this is the case, please contact the ISP to consult: your broadband access, authentication protocol used is 802. 1X it?If it is, a kind of authentication system may be added in the development process of private information, leading to failure of the router dial-up;
7, other configurations
1) Security Settings
When the Internet can be a normal, maybe for different reasons, you want the computer to the Internet operation of the internal LAN, open a different authority, such as allowing only some websites, can only send and receive E-mail, part of the limited, some do notrestrictions; user needs quite different in this regard, some routers can be achieved by some using a router is no way to fully achieve, such as "IP address and Ethernet address binding" function, the router can not do;
Our Internet operations, and its essence is the computer constantly sends a request packet, the request packet must contain a number of parameters such as: the source IP, the purpose of IP, source port, destination port, etc.; router is through restrictions on these parameters tocomputer to control the internal LAN access rights of different purposes;
Below we have listed typical configuration examples to illustrate the router "firewall settings", "IP address filtering," how to use these features?Cited examples and the red part of the explanation above, are as much as possible to help you understand the meaning of the various function parameters, only the understanding of the meaning of the parameters, you can configure the filtering rules arbitrary and quickly achieve your desired goal withoutbecause of configuration errors resulted in the use of these features, it will not because of lack of timely technical support to delay your application;
"Firewall Settings" page, you can see this is a master switch in the Settings page, do not use all the functions, please do not tick the check in front of it;
In addition to the main switch, and then there are two filtering "default filter rules" OK, what is the default filter rules?We have specific rules set the page, the definition of specific rules, eligible to control packet processing, while here the "default rules" by definition, limited is our custom not covered by the rules do not meet the packethow to do?This should not be difficult to understand it;
A packet, to do with our set of rules to you does not meet our set of rules but must comply with the default rule;
We can see that the default filter rules, you can add new entries fill; we configure a rule: Limit one computer within the LAN, IP address 192.168. 1.10, it only logged www.tp-link.com. cn the site, anything else will not work;
Above, this rule can be interpreted as: the public network within the network computer to send packets, the packet's source IP address is to limit the computer's IP address 192.168. 1.10, packet destination IP address 202.96. 137.26, which is www.tp-link.com.cn the domain name corresponding to the public network IP address, WAN request for the site because it is limited, so the port number is 80; rule set can be configured rules pageclearly see, the rules take effect for 24 hours, the control is the IP address of the object
192.168. 1.10 this host, LAN port default do not fill the back, enter the WAN IP address field is www.tp-link.com.cn the corresponding public network IP address, port number because it is so filling site80, the agreement generally select the default ALL on the line; whether to allow it?Because the default rules do not meet the set rules to prohibit the packet through the router, so packets conform to set rules allow, the rules for the entry into force of the state;
If you are involved in the rule to restrict the site, which is the purpose of requesting the port is 80, you should consider the port corresponding to the 53 corresponding data package also allows, because 53 corresponds to go, "DNS Server" datapackage for the domain name (such as www.tp-link.com.cn) and IP address (such as 202.96. 137.26) corresponds to, it is necessary to open!
Configuration "IP address filtering rules" used to implement this feature some of your purposes, the most important is the analysis of control have to do that, and then choose what kind of default rules?What kind of filter rules configured?If you are determined to understand the real role of this function, by careful reference and repeated the experiment on the router, you will be able to fully grasp it!
