Abstract
The invention relates to a local area network port proxy method for a port proxy server. The method comprises the steps that a table of a virtual machine is generated according to a proxy client side and an external port used by the proxy client side; a local area network access request sent by a terminal user is received; the corresponding external port is mapped in the table according to the local area network access request; the mapped external port is in communication with the corresponding proxy client side to obtain data in the local area network; and the data are provided for the terminal user. The local area network port proxy method for the port proxy server can break through self IP access limits, can completely replace port mapping in the prior art, occupies few cpu resources, is higher in transmission speed and better in stability, and increases convenience and speed for accessing a router through an outside network.
Description
Technical field
The present invention relates to lan port and act on behalf of field, particularly relate to a kind of lan port Proxy Method of port proxy server.
Background technology
Please refer to Fig. 1, extranet access internal server of the prior art need to be mapped to Intranet serve port on gateway, and the WAN mouth IP of outer net PC by gateway device adds that access port access application serves.Below the internal server of needs access is connected on other gateway devices, namely make secondary or when more multistage application service is used, we want remote access, just need the gateway device mapped port upward of one-level one-level to go out, until be mapped to one-level topmost.This mapping mode is very loaded down with trivial details, also compares spended time.If outer net is the mode of dialling up on the telephone, IP is becoming at any time, also needs the line bonding domain name for dialing, facilitates user to access.
Summary of the invention
The object of this invention is to provide that a kind of cpu of taking resource is few, forwarding speed is fast, the lan port Proxy Method of the better port proxy server of stability.
For solving the problems of the technologies described above, as one aspect of the present invention, provide a kind of lan port Proxy Method of port proxy server, comprising: according to the table of the outside port generating virtual machines of agent client and use thereof; Reception is from terminal use's local area network (LAN) access request; According to described local area network (LAN) access request, in described table, map out corresponding described outside port; By the described outside port mapping out, communicate by letter with corresponding described agent client, to obtain the data in local area network (LAN); Described data are offered to described terminal use.
Further, also comprise: described outside port is each agent client distribution by described port proxy server.
Further, also comprise: described outside port is arranged voluntarily by described agent client.
Further, described outside port is Random assignment.
Further, the each row of data of described table all comprises IP address and corresponding with described agent client, unique described outside port of a described agent client.
Use the method in the present invention, can break through the restrict access of self IP, can substitute port mapping of the prior art completely, and it is few to take cpu resource, the faster stability of forwarding speed is better, has increased facility and the agility of extranet access router.
Accompanying drawing explanation
Fig. 1 has schematically shown local area network (LAN) access process schematic diagram of the prior art;
Fig. 2 has schematically shown the local area network (LAN) access process schematic diagram in the present invention.
Embodiment
Below embodiments of the invention are elaborated, but the multitude of different ways that the present invention can be defined by the claims and cover is implemented.
Please refer to Fig. 2, the invention provides a kind of lan port Proxy Method of port proxy server, comprising: according to the table of the outside port Port generating virtual machines of agent client Client and use thereof; Reception is from the local area network (LAN) access request of terminal use User; According to local area network (LAN) access request, in table, map out corresponding outside port; By the outside port mapping out, communicate by letter with corresponding agent client Client, to obtain the data in local area network (LAN); Data are offered to terminal use User.
Preferably, also comprise: outside port is each agent client distribution by port proxy server.
Preferably, also comprise: outside port is arranged voluntarily by agent client.
Preferably, outside port is Random assignment.
Preferably, the each row of data of table all comprises IP address and corresponding with agent client, unique outside port of an agent client.
Please refer to Fig. 2, wherein SER represents port proxy server, and its address can be ac.wamwifi.com etc.
First, can in Internet, arrange a transfer server, this server is for the agency at Internet network.It as port proxy server, receives connection and remote access link from agent client in Internet network.
Secondly, the terminal PC installation agent client Client acting on behalf of at needs.For example, agent client Client can divide two kinds, and a kind of is that to need people be address and the port of filling in proxied device.Another is embedded in software, and only need to start agent functionality will remove Connection Proxy Service-Port automatically.
Wherein, agent client can get the internal resource in local area network (LAN), then by port proxy server, provides fixing outside port, and for example 3333, with port proxy server communication.
After communicating by letter successfully, port proxy server is given corresponding outside port of port proxy client Client Random assignment (or also can oneself outside port be set in port proxy, as long as in the port range of regulation).
At this moment, in port proxy server, can there is the table of a virtual machine, port proxy information and outside port that this table record is corresponding, in table, every data line is all corresponding 1 the unique port of 1 IP.
If USER(is terminal use) need to access the information in local area network (LAN), first by port proxy server, port proxy server automatically identifies the data of user's access, then gives corresponding port proxy client by the data relay identifying.So agent client sends to port proxy server by its outside port by the LAN data getting, like this, terminal use just can get the data of request.
Use the method in the present invention, can break through the restrict access of self IP, can substitute port mapping of the prior art completely, and it is few to take cpu resource, the faster stability of forwarding speed is better, has increased facility and the agility of extranet access router.No matter your server is internal resource or external resource, use this method all can allow your server data of user's successful access of outer net.
The present invention has adopted the port proxy server that possesses port forwarding function, possesses various port forwarding capability simultaneously, can stop the webserver and suffer network attack, guarantees the normal operation of server.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
