The real physical isolation
The physical isolation network Gate of the network has truly realized the physical separation between the two networks. The physical isolation network brake interrupts the direct connection between two networks, all data interchange must pass through the physical isolation network Gate, the net gate from the network layer seventh layer restores the data to the raw data (file), then transmits the data in the form of "the ferry file". No packets, commands, and TCP/IP pr

The Gateway technology in the network is also called the inter-network connector and Protocol converter. The gateway implements network interconnection on the transport layer. It is the most complex network interconnection device and is only used for different network interconnection between two high-level protocols. Gateways can be used for both wide-area Internet and Local Internet. A
Router and three-layer switch experiment Demo--a gateway that acts as a two VLAN--Hundred dishes background : We know that routers have routing capabilities, so you know how to configure two gateways on a router interface (such as a two VLAN gateway)? Note that it is on one interface instead of two, and we sometimes use the three-layer switch as a router, so how do we configure the three-tier switch at this

Nowadays, the Internet is playing an increasingly important role in our daily lives and work. It can be said that without the Internet, we will not be able to work and live normally. As a programmer, most of the programs we write will also be related to the network. To use the network, you must first set the network configuration of the machine. The manual setting method is obviously not desirable, so we need to let the program complete it for us. The following is a very common Demo of C # setti
Assume that you are a little bit (local host) and live in a Large Courtyard (local LAN). There are many neighbors (Network neighbors), and Ye Li, who looks at the door, has a data transfer room at the door, uncle Li is your gateway. When you want to play with a partner in the yard, as long as you yell his name in the yard (ping him), he will respond to you when he hears it, and run it out to play with you.
However, you are not allowed to go out of
