What kind of twisted pair cable is used to connect the firewall to the computer

Now the network cards are adaptive, parallel or cross can be used!

As long as the network cable is good, it's fine.

Firewalls are software, do you need wires?

1.The easiest way to connect two computers is to use a crossover cable to connect directly, if there is no crossover cable, use a hub or switch to connect together, set up as a workgroup, and the same IP address can be used.

2.It is directly connected with a cross line. The crossover line method is 568a at one end and 568b at the other, see below for details.

Standard 568b (with the wire facing straight forward): orange-white--1, orange--2, green-white--3, blue--4, blue-white--5, green--6, brown-white--7, brown--8

Standard 568a (when the wire is facing straight forward): green-white--1, green--2, orange-white--3, blue--4, blue-white--5, orange--6, brown-white--7, brown--8

Then set the two computers in the IP as follows: IP No. 1 is, IP No. 2 is, and the gateways of the two are set to the same to form two LANs, and the firewall can be turned off to achieve interconnection.

Method 2:

The IP addresses of the two computers can be set to be obtained automatically, or the IP can be set as follows: IP No. 1 is, IP No. 2 is, the gateways of the two computers can be set to the same, and the working group names of the two computers should be the same, so that it works. If you can't connect, sometimes it is affected by the firewall of the antivirus software, you can turn it off, or set the IP addresses of both machines in the firewall to allow passage.

Both computers are connected to the router, turn on the power of the router, see if the lights of the interface of the two machines are flashing normally, and then set the IP address in the properties of the online neighbor, and suggest one for you, and the other settings.

That's it. Of course, there are many ways to set up IP, this is just one, and it is not enough to explain it to you in 3 words. If you want to access the Internet, you can connect the network cable to the router at the root.

2. The two PCs are connected through the network card--- cross cable 3, the PC and the router are connected --- direct connection.

4. The X on the switch and hub indicates that the Rx and Tx inside the switch or hub have been crossed.

5. No x means that everyone already knows by default.

6. The uplink port of the switch is a cascade port, which is used for the connection between the switch and the switch 7. The ordinary port of the switch and the switch need to be connected with a cross wire, and the ordinary port of the switch and the uplink port of another switch are connected with a straight wire.

Note: The current switches have the function of automatic port identification, and the two switches can also be connected with a direct cable.

Direct connection to the network cable. That is, the positive line.

1. If it is an optical fiber switch and a firewall with optical port, it is best to use optical fiber cable to connect 2, if it is an ordinary gigabit switch and an ordinary firewall, then use Category 6 wire to connect 3, if it is an ordinary ordinary switch and an ordinary firewall, then use a super Category 5 cable to connect the line bought on the market or sent by the hardware firewall;

You can also make your own straight line, both ends are 586b: the specific line sequence production method: twisted pair clamp line order is consistent on both sides, and the unity is:

1, white orange, 2, orange, 3, white green, 4, blue, 5, white blue, 6, green, 7, white brown, 8, brown. Note that both ends are in the same line order and correspond one-to-one.

In the past, the theory was that the same kind of equipment used crossover wires, and different devices used straight-through, but now they all use straight-through wires, and now the network cards are 100 Gigabit and Gigabit self-adaptive.

Twisted pair reception is used in eight wires, 1 and 2 are sent through 3 and 6, it may be so, I can't remember exactly, or 12 send, 36 receive, hehe.

I'm not the answer. I did this topic, computer network assignment. But it seems that the netizens are too unprofessional...

No longer needed, the new devices are all adaptive.

Windows Firewall helps prevent hackers or malware from accessing your computer over the Internet or network. It blocks abnormal data requests from the Internet by blocking certain unused or sensitive ports, while also organizing abnormal local access to the network.

You can open the Control Panel's System and Security to set it up.

In general, Windows Firewall has no impact on ordinary Internet needs, but in some special applications, it is often necessary to turn off the firewall in order to work properly, such as port mapping, VPN and other services.

If you can connect locally, if your telecom dial-up connection, see if the password and the user are wrong, yes, the above server does not respond to Luo or fails, which was the case before.

Ordinary network cables are divided into two kinds, one is machine-to-machine, and the other is machine-to-hub, which is both the same equipment and the other is different equipment. First, there are two crystal heads for network cables, and different network cables have different practices for crystal heads.

There are two common methods of crystal heads, one is 568a, one is 568b, and the crystal head of the same equipment is composed of two crystal heads, one 568a and one 568b. The different devices consist of one or two 568A or 568B heads.

Here are two ways to wire the crystal head:

568a: green-white, green, orange-white, blue, blue-white, orange, brown-white, brown-white, brown568b: orange-white, orange, green-white, blue, blue-white, green, brown-white, brown-white.

Then you have to see if you have a broadband connection.

For example, the IP address of a computer is set to:

b. Computer settings are:

A computer Chinese right-click attribute Share the file, B computer use: win+r input After entering, you can copy the files of computer A to computer B.

First of all, you need to connect the pair, the computer is connected to the computer (not the computer is connected to the router and then connected to the computer), and the twisted pair is reversed. After connecting, right-click on the online neighbor, properties, there is an IP option in it. The IP of the two computers can only be different from the last digit, the others must be the same, the gateway is the same, and the submask is the same ( Then ping.

Turn off the firewalls.

It is very simple to configure the same network segment, for example, one is a mask and the other is a mask. Pay attention to turn off the firewall.

Do you use a straight line or a cross line?

1.The Working Group wants to be the same.

2.Two firewalls are to be turned off.

3.to enable network discovery and turn off password encryption.

Shoot to the same IP band.

Please, is it that hard? The first and most important step is to turn off the firewall. In particular, Windows comes with a firewall, and the second is not to change the IP, but to get it automatically. It doesn't matter if it's the last one you see in the bottom right corner.

Third, when you enter the game LAN, you can generally use Warcraft 3 as an experiment and build a map, and he can see you and be happy.

Plug in the network cable port, change the network neighbor adapter to find the link in the network, right-click the attribute, and change the IP to automatically obtain. Both computers need to be changed. The firewall is best turned off.

Save time and effort with a wireless connection, and it's also fast. One machine can add a temporary network to the management wireless network, and the other can be connected.

Turn off your laptop's firewall, turn on network sharing, and turn off password protection.

I've connected it, it's pretty simple. For example, if you change the IP address to 112 and turn off the firewall, you can connect to it. When you are in the company next time, you don't need to change anything, and you can directly have a memory function.

I think it's similar to XP.,You can use a general network cable.,The main thing to chase is to set it to a network segment of IP.,And then set up to share.。

You can connect it with an interactive network cable, or use one machine to build a local area network, and then connect the other to the sharing center to form a home network.
