The intranet is normal, but the access to the extranet is not normal a strange problem, ask for a m

1.Connect A, B, and C to the route separately to see whether it is normal.

2.Match AB, BC, AC, to the route to see if it is normal or not.

3.Finally, AB+C, BC+A, AC+B, go to the route to see if it is normal or not.

Through the above test, see which machine the problem is mainly focused on, hardware, mainly check its network cable (line tester), network card (replace a normal one) test.

On the software, install a 360, turn on anti-ARP attacks, and use the 360 software manager to see if there are ** tools in the system similar to eMule, bit elves, etc., and if so, disable him in the boot startup block.

There may be viruses that are automatically sent to the route, so that the lights of the route flash non-stop, indicating that there is a large amount of data congested in the route, use nod32 or Kaba to kill it, I don't trust the domestic antivirus software!

It is estimated that machine B is equipped with tools or software or ** tools that occupy a lot of network speed, and it can only be suspected that it is a problem with the machine. **The tool must be set up, otherwise it will affect other computers under the same route. Just look up what ** tools are installed in each machine.

This is obviously a problem with machine B, it must have installed some software that takes up network resources, or it has limited the network speed under A's IP, I don't know if you are A or C? If A and C watch movies regularly, B is likely to do so.

The Internet is set to automatic acquisition: The dynamic IP address acquisition of the router is generally as follows: and "x" represents the slave.

2.Check whether the router's wires are connected, connect the external network cable to the WLAN port, and then connect the VLAN port to access the host, and the internal network is connected to the VLAN port of the switch to access the host, 3There is no problem with the above, first connect the network cable provided by the ** provider directly to the computer through broadband dial-up connection to test the network problem, if you can't connect, it means that it is a problem with the network service provider.

What should I do if the internal network connection is normal, but the external network connection is abnormal?

Hello dear! I have seen your question here, and I am trying to sort out the answers of several friends, and I will give you a reply in five minutes, please wait a moment! ^

1.First check whether your intranet IP address and the external IP address are quietly guessed and deconfirmated, generally the intranet is set to manual, the IP range is: , and the external network is set to automatically obtain:

The dynamic IP acquisition of a router is generally as follows: where "x" stands for slave. 2.

Check that the line of the router is not connected to the WLAN port when it is enlightened, and then connect the VLAN port of Zhaopai to the host, and the internal network is connected to the VLAN port of the switch to access the host, 3There is no problem with the above, first connect the network cable provided by the ** provider directly to the computer through broadband dial-up connection to test the network problem, if you can't connect, it means that it is a problem with the network service provider.

Neither. We're two together, can we install it from scratch without this one?

Yes, dear.

Call mobile telecom to install.

That's right, dear.

1. First of all, you need to enable the external network on the remote computer.

Visit. <>

2. Then change the default remote port by the remote computer as such. The default is 3389, which can be customized and modified to others.

3. Ensure that the erection of the oak bridge in the LAN can be normal and remote.

4. In the intranet where the remote is located.

Install the nat123 client to add a mapping to connect the remote desktop to the intranet.

The address is mapped to the Internet.

5. On the Internet, remote desktop connection and access can be carried out through the mapped Internet address and Internet port.

It may be that the network cable is damaged or the IP address is set in error.

The solution is as follows:

In fact, with the help of professional LAN remote tools, control the LAN monitoring software can realize remote desktop control, realize the connection of the intranet computer, the use method is simple and convenient, there is no requirement for the external network network, as long as the computer is in the same local area network, the installation method is three steps:

2. Register an ID, log in to the control end and all the controlled ends, use the same account, and the controlled end can be set to start randomly at boot and log in automatically, without personnel on duty operation, and automatically go online.

3. Log in to the control terminal and check the online host to realize the control and operation of the remote computer.

Answer analysis: First, check whether your intranet IP address and the IP address of the external network are set correctly, the general situation is to set the intranet to manual, the IP segment is, and the external network is set to automatically obtain: the dynamic IP acquisition of the router is generally, "X" represents any number from 2 to 254, second, check whether the router's line is connected, the external network cable is connected to the WLAN port, and then the VLAN port is connected to the host, and the intranet is connected to the VLAN port of the switch to access the host, 3. There is no problem with the above, first connect the network cable provided by the ** provider directly to the computer through broadband dial-up connection to test the network problem, if you can't connect, it means that it is a problem with the network service provider.
