The problem of dual network cards, what is the dual network card?

Yes, under normal circumstances, the route priority of dialing will be larger, if not, please refer to the following settings.

route add mask metric 3 and then put Rename to the root directory of the C drive.

A gateway that represents your normal internet access.

At the same time, it can't be used.,The original test.,When you open the intranet, the web page of the external network must be turned off.,When you go out of the intranet, the external network is turned off.,Although you don't have to change the network cable back and forth.,But because there can only be 1 network card working.,So it's still troublesome when switching.。

No, it's just a public IP. Dual NICs are generally one public network and one LAN IP

If the IP address of the router shared in the office is set to the intranet, the IP address of the connected cat to the government network is set to automatic.

I don't know if the government network has any special requirements for network settings, if it is like ordinary Internet access, this connection method can realize ordinary Internet access and access to government affairs network. However, the NIC connected to the government network cannot be set to the same network segment as the IP assigned by the router.

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!

Benefits of using dual network cards to configure Internet access:

1.Economical -—— only need more than 10 yuan to buy a network card and a network cable;

2.Stable - much more stable and fast than using ** software;

3.Practical - can break through any restrictions taken by any broadband service provider (China Telecom, China Unicom) for sharing multiple users on one account.

Dual network cards refer to the installation of two network cards on a computer (there can be one network card with two RJ45 interfaces, which is equivalent to one or two network cards).

But if you want to share your ADSL without going through a router, you can use the ICS (Internet Access Sharing Service) that comes with Dual Network Cards (XP) to achieve simultaneous Internet access for multiple people

The connecting party is not: the network cable out of the adsl cat is connected to one of the two network cards, and the other network card is connected to a network to other computers (or switches), and assuming that the IP of this network card is, then, the IP of other computers is set to not be the same), the gateway is set to this, so that all computers can share the Internet

Of course, dual network cards are not only for this function, such as making soft routers, etc., all need dual network cards and multiple network cards
