Dual NIC Question 110, what is a dual NIC called?

I've been studying this question for a long time, but it seems that there is no solution at the moment, if you are paid by the company, you can buy a DNS server to merge the two networks, but if you have a network card, you can't, I have been researching for basically 1 month, and this is the answer.

I'm also dual-network and dual-network. All settings are set to automatically obtain IP addresses. You can go to both the internal and external networks.

I don't understand why you all have to get dual network cards, dual network cards need 2 network cables, you all go to ** connection?

Does the company use a network card? You disable a network card, can't you set it according to their IP settings?

There must be a gateway on the external network.

It's achievable!

The movie server in my internet café has four network cards!

A network card and B network card are bonded to one IP, which is used for the intranet when the client watches movies.

I made the server, so I know very well and I hope I can help you!

You have to make it clear! Why do you use zero segment on the Internet? Why do you use a paragraph for the intranet? Could it be that your company's extranet router is zero-segment? What is an intranet? Is it necessary?

In your case, NIC A is an internal network and NIC B is an external network. However, you cannot use both intranet and extranet resources at the same time.

Method 1. 1: Turn off (do not specify) the gateway and DNS of NIC A (intranet).

2: Set the IP, mask, gateway, and DNS of the external network.

If not! Try again!

Method two. Disable NIC A

Only use NIC B, first set up the external IP, gateway, DNS and so on of NIC B!

Finally, add an IP address (IP and mask of card A) to the network attributes of card B

The function is: make the B network card become two IPs, and use the resources of the internal network and the external network at the same time!

B network card must first write the IP, DNS, gateway and other settings of the external network!

Then add the IP and mask of the intranet, and then add the IP when you too.

You can only add IP and mask, and the IP and mask you add in the last step are you.

IP in the intranet!

According to you, method 1 should be useless! Method 2 works!

The second principle of method is: use a network card, set the main IP as the external network, and add an IP as the internal network!

That is, only one network card is used, if you put two network cards, you have to disable the other one before you start setting! Pay attention to the prompts during the setup process!

I have four network cards, and I can use two external networks and one internal network at the same time, why can't you? Give it a try! Good luck!!!

What are the benefits of using a dual network card? The so-called dual network card, is to bind the dual network card to an IP address through software, this technology is not unfamiliar to many friends, many high-end server network cards (such as Intel8255X series, 3com server network card, etc.) have multiple network card binding function, can be bound to two or more network cards on the same IP address through software and hardware settings, use it as if using a network card.

There are many advantages of multi-network card binding, first of all, the bandwidth can be increased, if the bandwidth of a network card is 100m, theoretically two network cards are 200m, three is 300m, of course, the actual effect is not such a simple increase, but after the actual test the use of multiple network cards for increasing bandwidth, maintaining the stability of bandwidth is definitely beneficial, if the switch and other related conditions are good, this effect is still very satisfying; Secondly, can form a network card redundant array, share the load, after the dual network cards are bound into "a network card", work together synchronously, and the access traffic to the server is evenly distributed to two network cards, so that the load pressure of each network card is much smaller, the ability to resist concurrent access is improved, the stability and pleasure of server access are guaranteed, when one of them fails, the other immediately takes over all the load, the process is seamless, and the service will not be interrupted until the maintenance personnel arrive.

Oh you can only add a router,Telecom is bound to the MAC address of your network card,You can't get on the network if you change the host and don't apply,So when you buy a router, you must buy the kind that cracks the starry sky.,You can buy a 1-to-4,But a broadband with three computers must have a very fast network speed! That's only about 100 dollars!

One computer with two network cards.

On one motherboard, two network cards are inserted or integrated!
