port mapping (Port Mapping): Many customers have asked why every port mapping? For example: the Internet through a router, you can visit their website, but others can not; enter 127.0.0.1 can access, others still do not see; type localhost you can see, but others have not seen any, angry ah ~ no way, Only for a port mapping (router port mapping - This tutorial is suitable for all Tplink-TLR-402 series router set up under the web server, mail server, PW server, monitoring server, remote server, housekeeper Kingdee financial management server, VPN, ERP ,UGG Boots Sale, ftp server, port mapping, etc.) to use port mapping first, simply tell you what port mapping: also known as port forwarding port mapping, also known as virtual servers, each a different brand of router, it is called is not the same. But the operation is the same. Specific examples can sign http://oray.0755ok.net model operation simple and popular explanation of view (we prefer to see this): the process of port mapping port mapping process is as: your home in a district in 2410, Building B, Room, you Friends come to you, find the cell door, do not know where you live layer of No.? Asked the porters, security, security is very polite to tell him your house numbers in detail, so your friends easily find your home. This process is the external network access within the network through port mapping metaphor. Here are the next port mapping in the terminology used. In network technology, the port (English Port) has several meaning. Hubs, switches, routers, port refers to the network device is connected to other interfaces, such as RJ-45 port, Serial ports. We are talking here of the port, not the computer hardware I / O port access, but the software formal concept. Server can provide a variety of outside services, for example, a server can be both a WEB server, FTP server can also be, at the same time, it can also be a mail server. Why a single server can provide so many services? One of the very major area of ​​concern is the use of different services provide different services to ports, such as: WEB using port 80, FTP uses port 21 and so on. In this way, through different ports, the computer communication without interfering with the outside world. Our ports are not referred to here refers to the physical sense of the port, but specifically refers to TCP / IP protocol in the port, the port is a logical sense. Port mapping: a computer within the network to open services on the Internet or receiving data, you need to port mapping. Divided into dynamic and static port mapping Dynamic port mapping: within a computer network to access Sina, will send data packets to the NAT gateway, the header including the other (that is, Sina) IP, port and local IP, port, NAT gateway will the machine IP, port, replace your public IP, an unused port, and will write down the mapping, forwarding data packets for later use. And then the data sent to Sina, Sina respond after receipt of data, send data to the NAT gateway that does not use the port, the NAT gateway will then forward the data within the network to that computer, to achieve within the communications network and public network when the connection is closed, NAT gateway will release the connection assigned to this port, so that future connections can continue to use. Dynamic port mapping in fact is the NAT gateway work. Static port mapping: that is, open on the NAT gateway to a fixed port, then set the port to receive data transmitted within the network to which IP and port, whether or not connected, the mapping will always exist. Initiative on the public network can access a computer within the network. An overview of port mapping utility, [1] First, we will vidcs.exe spread public IP on the public network ports on a computer running vidcs p, such as vdics p5205. What this means is listening on the public network computer within the network port 5205 and then returned to the computer, just click run vIDCc.exe explain the above settings, VIDC service IP, means for monitoring the operation of the vidcs.exe IP port address, port refers to is in the public Internet listening port,UGG Boots, above my listening port is 5205, bindip out means you have to open within the network IP, Bind port means you need a computer within the network for open ports (FTP server port is 21, WEB service port 80, mail service port 25) which you would like to fill in which it opened. Means you want to map the port to which port to provide public network services. Port given by you, fill out, we point Continue to point In this way, your machine on port 80 open out. Access method http, / / ​​public network ip, port mapping. Such as http, / / ​​210.210.210.210,8080 two, WinRoute Pro's port mapping feature WinRoute Pro is a work in NAT (network address translation) mode of Internet sharing software. It comes with a port mapping function itself. Run WinRoute Administration and log in the main menu, select Add port mapping entries. You can set options, including the protocol, monitor port, port type (single port or a range of serial port), destination host, destination port. Third, the router port mapping technology in the enterprise routing applications, many companies often use port mapping to be completed, and now, almost all routers support port mapping has been, we use an example how to use the TP router port mapping function, enter TPlink router, because that is forwarding port mapping, so we went inside to set forwarding rules,UGG Boot, select specific applications, add new entries, enter the port you want to trigger the port forwarding, for example, I need to map port 21, then I fill in 21, the trigger agreement not to modify, ALL representatives to support all protocols, we need to open port forwarding for the same input port, fill in 21, open protocols also need to change, select ALL, the state selection effect, then save to the port here will all add to complete the mapping rules , the following would have been in force.
