How to set the IP of two network cards to connect three computers 20

The easiest way is to set the gateway up:

Three NIC IPs:

Net Mask: That's it!

There are three ways to solve the problem, one is to share the broadband connection, right-click on the broadband connection, there is a share, he will automatically ask you whether the machine sets the IP to, at this time, the IP of the other machine should be set in the same network segment, that is to say, it should be set to,, gateway, subnet mask,. The second is the bridge, right-click directly on the local connection, and there is a bridge. The third is to use third-party software, Sygate.

I recommend using the third method, which is very convenient for monitoring another computer. Get in touch when you want to use whichever way you want.

Unless your PC is configured with Routing and Remote Access. Otherwise, both network cards are connected, so you can't access any network.

The other subnet mask is the gateway.

If your computer is used as a gateway to this network, then in the network card connected to the intranet, only the IP address and subnet mask can be set, and the default gateway does not need to be set. For other computers that access the Internet through your computer, the default gateway should be set to the IP address of your computer's intranet NIC.

The IP addresses of the two NICs in the dual-node peering interconnection can be set to the same network segment, such as AND and .

The other NIC of the dual-NIC machine does not need to be set, as long as it is connected according to ADSL.

Then enable ICS connection sharing in the connection, and set the gateway of the NIC machine to the NIC IP of the machine connected to it, so that the two machines can share the Internet.

Even the cat is set up according to the stand-alone Internet access, and the other is OK as long as it is set to the same network segment as another machine, such as, subnet mask.

The problem is your gateway, you only need a gateway, then you need to delete a gateway, route delete If you delete this gateway can only go to the mailbox, but not on **, then restart the computer, and then delete another gateway againRoute delete, try, if it is successful, then you can create a batch file, and then add this command to the automatic run, because the XP system will recover the routing table after each restart.

I don't know what brand your router is, but now broadband routers have MAC address cloning function.

You use the host (that is, the one bound to the IP and MAC) to enter the router settings, select the fixed IP mode to surf the Internet, and then find the MAC address cloned, click on it to clone the MAC address of the router to your host.

When connecting other computers to the router, assign and set the IP address, the gateway is the router's IP address, and the DNS is also the router's.

A network card on the host is used as an external network, and a network is used as an intranet

If yes, then you don't need two network cards, because telecom gives you a dynamic IP, which changes every day, as long as you use a router, this is for home Internet access.

If not, you don't need routing, it's fine, as long as you know that the IP of the public network is set to such as this is the intranet.

The other premise is that if this is a public network, you need to know the public IP assigned to you by your telecom

If you have to route, then you need to do NAT address translation on the route, and convert it into a public IP --- this is for the company.

If there is a router, it is OK to do DHCP on your host

Just set up one, the network card that connects to the company, and set it to the same network segment as the company's other computers. For example, if someone else is the previous one, you can change the last 10 to etc.), the key is the network card that connects to the Internet, and if you surf the Internet is adsl, you are dial-up to connect. Attribute.

Just set up the network card that connects to the Internet.

What unit do you belong to, and are your computers restricted?

A only use a network card, another network card does not need to be set up or check the network cable, you plug in the network cable and speed has nothing to do with it, it is recommended to remove the network card! B's network card can also automatically obtain the IP, and the router has the function of automatically assigning the IP.

Since there is a land rover, it is better to let B connect directly to the land rover.

If the line is not well arranged, then bridge the two NICs on A, and only configure the IP of the bridge to be automatically obtained.

Then B and A are connected with a cross-twisted pair and the IP is also set to auto-fetch.

Of course, the reason for the automatic acquisition is that DHCP is turned on the land gamer, and if the land game does not have DHCP turned on, it must be set manually.

If you have a router, you can directly connect the two computers to the router separately, and the router can be connected to the modem. Computer A does not require dual network cards.

In a nutshell, you can cancel the gateway of the B NIC and you're good to go.

It should be a gateway conflict, a computer can only have one gateway, and the other subnet is a static route. And this subnet, in fact, does not need dns, this is a large subnet, static route is in cmd mode, run route add command, depending on the ? Okay, but this subnet can actually be accessed without routing.

Check whether DNS is configured for a network card, if not.

If it is a 2000 system, if the dual network cards are of the same model, there will be only one network card.

DNS is not a gateway, and DNS is configured for local telecommunications.

The route is set to automatically try.
