Dual network cards, direct network cables, and some problems with Internet access 100

If it is WinXP, you don't need to install Sygate, for convenience, the assumption is as follows: The two network cards of machine A are A network card and C network card. The network card of machine B is a network card of B.

The A machine uses A network card to connect to the cat. and set to PPPoE (if ISP is PPPoE dialing).The C NIC and the B NIC are connected with a crossover network cable. Both C and B network cards have local connections. The local connection of the B NIC is automatically set.

PPPoE is set up as usual and Internet connection sharing is enabled. C network card is also set automatically, after completion, C's local connection and A's PPPoe are selected with a right click, and click bridge. Get!

I've done this and feel that XP is a relatively easy system to use.

In the whole process, the network card should not be set incorrectly, and the AB machine connection cable should be crossed.

After enabling connection sharing, the address of the C NIC of machine A will be automatically set to, the address of machine B will be automatically obtained, and the DNS will also be automatically obtained.

You have two problems here: Problem 1: Machine B can't use the sharing of machine A to access the Internet.

Question 2: Machine B needs a password when accessing machine A through the LAN.

1IP2 mask:

3. There is no gateway.

1A After the Internet is connected, the IP does not need to be moved.

2 Local Connection Properties - Advanced - Internet Connection Sharing - First Selected.

B machine settings: ip:

Mask: Gateway:

Problem 1 solved.

Problem 2 solved.

Be kind, and if the problem is solved, remember to give it to me!

Machine A has dual network cards, and then interconnects with machine B through network cables.

A machine is the host, is the installation of SYGATE, LAN network card for the gateway? That's fine, you don't have to change it.

Internet This is the setting of the network card that you can access to the Internet, if the A machine itself can access the Internet, it means that the IP setting is correct, do not change.

IP of the B machine:

Gateway: How should I set up DNS? The DNS resolution service provided by the network service provider, I am from Northern Netcom.

I am now on machine B, the gateway is, and the DNS is not set.

The current status is: machine A can see each other on the Internet, but machine B cannot enter machine A, prompting that there is no authority and password, and machine A can enter machine B, but now machine B cannot access the network.

You can turn on the guest user of machine A.

Install the Sygate client on the B machine, select Automatically search for the Sygate gateway, and try whether it can share the Internet.

The two NICs of machine A are bridged, and the dial-up of machine A is shared.

The B machine sets up the network installation wizard, in which you select "This computer connects to the Internet through other computers on the network."

Go ahead and try it, we used to be like this for two years.

If you want to use SyGate, then you need to set Sygate (including ports), and then set the **server to ::port on machine B.

In general, the interconnection of devices of the same nature uses crosswires.

For example, the PC-PC switch-switch (non-cascaded) router-router (non-cascaded) can be crossed because of the general 568b line sequence: 1,2 is used to transmit and 3,6 is used to receive.

Ordinary twisted pair. The two-machine interconnection uses crossover wires.

The dual-machine interconnection uses a crossover line, that is, 13; 26 reverse twisting.

The prerequisite is that you need to have two network cables that can be connected to the external network. If you don't say anything, it's useless!!

Oh no, you can only use a network card.

What are the bottlenecks of slow internet speeds? Gigabit LAN or 100 Gigabit LAN card? What is the rate of entry?

If you have a router, you will use a router, but I don't understand what you mean (need a client to surf the Internet), is it necessary to authenticate to access the Internet? Do you use client authentication? In that case, you'll have to let your XP desktop take on the role of tethering.

If it's a traditional PPPoE type of certification, the best thing to do is to use your router to access the network.

Didn't understand what the client meant.

But as long as there is a router, isn't it simple?

**Wire - Cat - Router - Two computers.

If you don't use a router: ** line - cat - computer 1 - (cross line) - computer 2, computer 1 connects the network card 1 of the cat to share to another network card 2, and the network card 2 sets the IP to another network segment as the gateway of computer 2.

1. If you want load balancing, that is, the gateway of the two network cards is one, then you should use port aggregation, and the host needs software support, and the uplink switch needs to be able to support it.

2. If the gateways are different, then you can only do the traffic to a certain place through a specific network card, similar to the Internet café dual-line access. Specifically, suppose NIC 1, gateway, NIC 2: gateway, only set the gateway for NIC 1, and leave NIC 2 gateway blank first.

Now the traffic is all going to NIC 1, and then the traffic you want to go to NIC 2 is going to DOS

route add mask

That's it. In addition, you may be taking Netcom and Telecom at the same time, so you can go to the Internet to find the full IP address range of Telecom, roughly summarize, and then set up routing.

Note that doing so reboot requires a reconfiguration.

It doesn't make sense for you to do that. I thought that the two network cards could share the tasks, how could this be. Even if it is done as port aggregation, it is a server working, what's the use.

If you think that this server is not working, it is better to add another one to do load balancing, which is an effective way.

But it can be this: if your machine is a 2003 system, you should use load balancing in it. Setting a virtual address for the two NICs allows them to share the workload, but this itself is useless in reducing the burden on the server, and can only be said to add a reliable link.

It doesn't make sense to use the same network, generally dual networks, one telecom, and one Netcom. The double network used in this way makes sense, and it is used for space. Telecom users access through the telecom line, Netcom through the Netcom line

No, you need 3 network cards, one machine as a server, install two, and use this one to access the Internet. The other machine is used as a client, and one is installed and connected to that machine.

What is a dual system?

A dual system is one or more hard disks on a single host with two or more operating systems installed.

So the dual system has no connection with the dual network.

A network card can enable two systems to access the Internet.

Isn't it possible to run two systems at the same time?

Looks like I've been doing this experiment for a long time. The timing of my test is not feasible.

You can try to play like this. Install a virtual machine. You're in the virtual machine using the Netcom line. You use the lines of telecommunications on a physical machine. That's no problem.

This one will definitely do.

Dual network cards and dual IPs.

When I was in college, it was a two-line, a telecommunications network, an education network, and it was actually very simple to go on both sides at the same time, just add routes.

There's a log in my QQ space that is written in detail.,I won't talk about it here.,Although you want i me.,You go to my space to see.。

Landlord, let me tell you something: The current system protocol does not seem to handle the communication of 2 different service providers at the same time, except for the use of special equipment (such as the two-wire access thing you said), "realize the simultaneous Internet access of two lines of computer A and telecom?" ”

Not both, but you can choose to.

If you want to dial up, dial up, if you don't want to dial, the router shares the Internet, and the B computer is connected to the router, and the cable that connects you to the router is unplugged and directly connected to the B computer.

If you dial up a computer and connect to B, you can also share to your telecom network according to the dual network card, there are such ample network access conditions, so luxurious! You can play however you want, and you don't have to complicate things

A little advice

It seems that no, but you can install a virtual machine, and install the system on top of the virtual machine to connect the network from another network card. Or let computer B connect the line of Internet communication (plus routing), and then the telecom on computer A (dial-up is also OK), and the other network card sets a static IP and subnet mask, no gateway, DNS is set to the IP of machine B, and install a ccproxy on machine B to do **. At this time, you need to connect to the software settings of the network communication line on the A machine**.

There seems to be software that allows the program to specify the network card to go online.,I forgot the specific name.。

Yes, software support is required.

The easiest way is to build two wide connections in XP, but then there is no load balancing, so use sea spiders to achieve it

Let's build two broadband connections.

If both are win me, then click on the sharing of online neighbors, if the two are xp systems, then you need to set up the network management, as for the connection, a network card in, a network card out on it, nothing to change, the key is that the two drivers do not conflict.

There should be at least two network cables, how can one be enough? One directly connects to the Internet to open the shared connection, and the other points the gateway to it. . .

Do Internet connection sharing. You don't need a switch for two computers, you just need to make the wires into peers.
