How to open a port for ADSL dial up Internet access? 20

1. Answer the first question first, the system has such a function, enter your external network IP: map port, so that you can log in to your computer, provided that you have to set up to allow remote before you can achieve it.

2. What is port mapping, port mapping is a computer or server you want to connect to a single channel, his role is to support a software or function can be used remotely or network, general routers have, as shown in the figure! Your computer IP should be fixed, and then set up the port mapping, as if you can set up the mapping of your external network port number and route in the remote of the system, and then you can practice it.

1. If you don't have a router, don't think about it, you can't get in without software 2. If you have a router, you need to do 2 steps, first map your 3389 port (method: find the virtual server option - server port 3389--- IP address is the IP address of your computer --- protocol select all--- enable - save) and then apply for a peanut shell dynamic domain name resolution account--- find the dynamic domain name resolution place in the router and enter it, Because each router is different, I believe you can find it, enter it and click the link on it, and finally right-click on my computer - Properties--- remote --- allows users to remotely link to this computer on the hook. You try it, hehe.

If you are ADSL, it is absolutely impossible to achieve!

ADSL WAN port IP is a LAN IP, which means that there is a firewall on top of your home router.

And you can only map your internal IP to the WAN port of your route, and the firewall above does not do the mapping!

To do this, you have to pull the line! The leased line is a WAN, and you can directly map your internal IP to the WAN to achieve remote access!

Physical Connection

1. The network cable from the cat is connected to the WAN port of the router, and the computer uses the network cable to connect to the LAN port 1-4 of the router.

2. Check the indicator light, when the router is running normally, the power indicator (PWR) is always on, the system indicator (SYS) is flashing, and the WAN port and LAN port are always on or flashing.

If the sys is always on or off, it means that the router is faulty. If the LAN or WAN indicator does not light up, check whether the physical connection is connected, for example, there is no network cable or the network cable is not in good contact with the interface. If the connection is normal but the indicator does not light up, it may be a network cable problem and we recommend that you replace the network cable.

Set up your router].

1. Enter the IP address of the LAN port of the router in the browser, and enter the management page after filling in the management username and password of the router correctly in the pop-up box.

2. Select "Quick Settings" and "ADSL Virtual Dialing" in the left box, and then fill in the username and password of the broadband account in "Internet Access Account" and "Internet Access Password".

Choice of connection mode:

"On-demand connection" is recommended for timed Internet users, the router will automatically dial up when there is access to data, and if there is no data, it will automatically disconnect the network connection within the set time.

Auto-connect" is recommended for monthly users, and the router will be automatically reconnected after powering on or disconnecting.

"Manual connection" means that the router will not automatically dial by manually clicking on the connection.

3. The connection or disconnection operation of dial-up can be realized by clicking the "Running Status" column in the sidebar box on the left side of the management interface, and clicking the connection disconnect button in the "WAN Port Status" in the right box.

If the computer does not set the DNS server address, you can fill in the DNS server address displayed in the WAN port status display into the computer.

You didn't make it clear, the cat is in the living room, where is the route? Now I want to surf the Internet at the port of the study, is the port of the study a dark line at home? Is it directly connected to the router with a dark wire?

Check whether the NIC is disabled, or if the NIC drivers are installed correctly, and whether the network cable is connected correctly.

Right-click My Computer--- left-click Properties--- look at the network adapter in Hardware --- Device Manager. A yellow question mark or exclamation mark indicates that the driver is not installed correctly on the device. If it is disabled, it is OK to use it, and there may be a problem with the network card.

This can be done by following these steps:

Step 2: On the pop-up login page, enter the router username and password (you can view the nameplate at the bottom of the router).

Step 3: Then fill in the broadband username and password you are using and save it.

Step 4: Connect via router dial-up.

1. Connect the computer to the cat (broadband network cable).

First of all, please plug the network cable from the network port of the cat into the network cable interface of the computer.

If you don't use the cat for your home's broadband, then plug the Internet cable directly into the network port of the computer.

2. Use a broadband connection to dial-up the Internet.

1. Open the "Broadband Connection" program in the computer desktop, fill in your broadband account and broadband password in the program, and then click "Connect", and you're done. This is shown in the figure below.

2. Open the "Broadband Connection" program on your computer's desktop.

The same setup as the wired router, after that, after unplugging the network cable on the computer, it is good to receive the wireless.

How to set it up:

Router Setup Tutorial].

Home Network Environment Cabling]:

1. There is a telecom cat: the telecom cat --- router WAN port; The LAN port of the router --- a computer.

2. No telecom cat: network cable --- router WAN port; The LAN port of the router --- a computer.

Computer enters the router]:

1. Check your IP first, method: win+r--- enter: cmd--- enter in the black and white interface: ipconfig, press enter.

4. The router login interface pops up, enter the default login username of the router: admin and password: admin (if it is incorrect, look at the back of the router).

5. The above methods do not work, in the reset router. The address, account number, and password are all on the back of the router.

Set Router Dialing]:

The IP and DNS settings of the computer are automatically obtained.

1. Enter the router. In the [Setup Wizard], select [PPOE Dialing] (some are ADSL dialing), follow the prompts to enter your Internet username and password, and save.

2. In [Network Parameters] --WAN Settings], select [Normal Mode], and select [PPOE Dialing] in the three options of [Connection]. The next step is to select [Auto Connect], Save, and Exit.

3. If you want to use wireless wifi, your router must have a wireless routing function, in the settings, turn on the wireless routing function, here, the wireless signal signal is changed to one of them. The strongest anti-interference.

You can also set a password for your Wi-Fi connection.

How to open the gateway configuration interface of the wireless router:

2.Open the computer browser and enter the gateway IP address of the nameplate on the back of the router (generally, enter the router account password, and the nameplate on the back of the router is usually written.)

Do you think this software can be developed by telecom operators, so there is no beauty and practicality, hehe! You still have to go to the landlord theory, he insists on saying this, you just ask this broadband is **, you go to the operator's service hall to find the engineer theory!

The router has a MAC address binding function, which can copy the MAC address.

Unable to connect to the specified server, the port used for this connection is down.

Problem: Due to an error in the last connection and the short interval between redials, the server is too late to respond to your username and password.

Workaround: We recommend that you try again after an interval of one to two minutes.

Please make sure that the account number and password are correct. At the same time, there is no arrears.

The equipment of telecommunications is not good, and the resources are insufficient.

"Telecom" does not refer to China Telecom, but to telecom operators that provide network services.

Is it ADSL?

You can click the link a few more times to prove that the account password is no problem.

If it is a company, it is related to the company's host, and if it is a telecom ADSL, it is related to the telecom server.

Either your cat is bad or your network card is not good, you check it out.
