Connecting the router to the internal and external networks???

Your router is now using the NAT protocol.

Add passively open port 7226 to your router settings. Then set it to your machine's IP and you're fine.

Another recommended software is very good and convenient called battlelan, which is specifically designed to deal with this situation.

Find out for yourself.

1. Connect to the external network, and insert the ADSL cable from the cat into the enternet interface.

3. Set up pop Internet access, enter the user's name and password (similar to ADSL settings) 4. OK all the way, don't set up other things.

5. Intranet connection, make the network cable, directly insert it into the 1 10 port, and directly connect the other end to the computer network port.

6. Set up the network in the same workgroup, do not specify the IP address.

7. Just restart.

Of course, you can't use it, because your IP is the internal network address, and your external IP address is the address of the router, and there is a possibility that your router is connected with other routers with network cables to form a local area network, and the IP can be set separately.

Just turn off the firewall and set the IP again

You're going to have to set up a working group and fill them all in lately.

The continuous expansion of the Internet scale and the emergence of various large data services have greatly increased the requirements for the packet processing capacity of routers, so do you know how routers connect to the Internet? Here are some information I have compiled about routers connecting to the Internet for your reference.

The method of connecting to the external network by the road:First of all, in the local telecommunications bureau, ** bureau, Netcom, etc., the Internet number applied for, with annual or monthly subscription, will give yourself a username and password, which is the username and password on the dial-up for your own Internet access.

Click Setup Wizard Next.

Select [ADSL] Virtual Dialing (PPPOE) and click Next.

The network is divided into intranets.

And the external network, the internal network is a general reference to the company, school, family of the inner Ling Xiang Suimin network that is, the local area network, the external network mainly refers to the Internet, the external network is connected to the router, this is not necessarily, you can connect the road guess Wang Zhi by the device, you can also connect to the modem, both can be.

1. Connected to the cat, the computer needs to enter the account password first, and if you don't need the account password, you can link it directly.

2. Connected to the router, you need to set up the router first, after the router is connected to the network, the network cable is plugged into the router, and the computer can directly access the Internet, no need to log in to the broadband account.

3. Light cats. A network cable needs to be connected to the router.

4. If it is a wired router, then a network cable is also needed between the router and the computer.

Extended information: The optical modem has 4 interfaces, of which the first interface is connected to the router; The second interface is connected to the set-top box; The 3rd and 4th interfaces are connected to the computer and the switch in turn; Do not confuse the connection ports, otherwise there will be a signal failure. In addition, there is a login at the bottom of the mobile modem**, and users can register on the official website for settings.

Each home room has a different layout, so when installing, it is best to conduct a signal test and install the optical modem in the location with the best signal coverage possible.

If the conditions do not allow, only some repeaters can be installed with assistance.

Or add an additional router.

Secondly, the optical modem is used in active devices, and there will be heat during operation.

phenomenon, if they are installed in a sealed or stacked place, it will affect their signal transmission. Try to place the modem in the center of your home to avoid signal congestion or interference.

Can this silver potato understand.

But at present, most of them have not been defeated by the optical modem. Some of the complex networks of the Frontier Explorer also have multiple routes.

Generally speaking, the total gateway is the access.

Open a server on the machine, the external network should be accessed through your router, which requires the router to have the function of virtual server settings, for example, tp-link has this function, and another condition is that the IP address obtained by broadband dial-up is the public IP, these two conditions are indispensable, otherwise it is impossible to open external network access. Here are some ways for you to set up external network access on routers, I hope it will be helpful to you!

How to configure external network access on the router

Open the router settings interface (mine is a Xiaomi router), other brands of routers are similar, select Port**:

Here is an explanation of why the port is chosen**: because the external network wants to access your computer, it needs a port, and the port is equivalent to a door, which cannot be accessed by others without opening.

Let's add a port: Look at the practice in the figure, which port you need to access from the Internet, add which port, for example, I open ports 8080 and 29200, and add it like this

Of course, pay attention to the port added above, the port filled in later can be changed, but the second port of input can not be changed, and the first port of modification is to prevent visitors from knowing the local port you opened and maliciously attacking your computer. After the addition is completed, it is shown in the following figure

Here I also want to remind that some children's shoes don't know how to see their local IP address, press win+r and enter cmd enter, and then enter ipconfig enter to see the ipv4 address, which is the local IP.

When the Internet comes to access your computer, you only need to configure it for example: :15000 to access your computer.

In view of the fact that the public IP address of the vast majority of people's networks changes every time the cat is restarted, we can use DDNS software to bind the domain name, so that every time someone else comes to visit, it can be accessed directly with the domain name without the need for an IP address, as shown in the figure

After the addition is completed, as shown below: when others want to access it in the future, you only need to enter the information in the purple box to connect to your computer.
