With the development of the information network, people are bound to encounter some problems in the process of using computers, and for some computer terms, if you are not a professional, you may be at a loss when you encounter these problems. In fact, the gateway has a very simple understanding, that is, when we go from one space to another, we will inevitably go out or enter the door, right? that is to say, we will inevitably pass through a door, and the gateway we are talking about is actually "this door". Follow me down.

Introduction to Gateway:

Refers to the "gateway" at which one network is connected to another. In the Internet network, the role of the gateway is an intermediate device that connects the intranet with other networks on the Internet, which is also called a "router". Gateway address is an address that can be understood as a channel for information transmission between intranet and Internet network. According to different classification criteria, there are many kinds of gateways. In TCP/IP protocols, gateways are most commonly used, and the "gateways" we talk about in this place all point to gateways under the TCP/IP protocol.

In-depth explanation:

In essence, a gateway refers to the IP address of one network to other networks. For example, there are Network An and Network B. the IP address range of Network An is "192.168.1.1" 192. 168.1.244 "with a subnet mask of 255.255.254.0; the IP address range of Network B is" 192.168.2.1 "192.168.1.254" with a subnet mask of 255.255.254.0.

When there is no router, there is no TCP/IP communication function between the two networks. Even if the two networks are connected to the same switch or hub, the TCP/IP protocol can also determine that the hosts in the two networks are in different networks according to the subnet mask (255.255.255.0). In order to communicate between the two networks, what must be done is through the gateway.

If the host in network A knows and finds that the destination host of the packet is not in the local network, the packet will be forwarded to the gateway to which it belongs, and then forwarded by the gateway to the gateway to which network B. the gateway of network B then forwards it to one of the hosts in network B. Like this, network B forwards packets to network An in the same process as the night market.

I don't know if the above knowledge can help you when you have a problem. In fact, there are two ways to set up the gateway, one is manual method, the other is automatic method, if you are a computer rookie, then I suggest you use automatic method to avoid making mistakes again. Of course, there are some automatic methods and steps, but it is easier than manual, which is suitable for beginners to do. I will not repeat the specific steps here, you can search the Internet on your own.
