Embodiment Construction

[0012] Embodiments of the invention are described in detail below, but the invention can be practiced in many different ways as defined and covered by the claims.

[0013] Please refer to figure 2 , the present invention provides a LAN port proxy method of a port proxy server, comprising: generating a virtual machine table according to the proxy client Client and the external port Port used by the client; receiving a LAN access request from an end user User; according to the LAN access request Map the corresponding external port in the table; communicate with the corresponding proxy client Client through the mapped external port to obtain the data in the LAN; provide the data to the end user User.

[0014] Preferably, it also includes: the external port is allocated by the port proxy server for each proxy client.

[0015] Preferably, it also includes: the external port is set by the proxy client itself.

[0016] Preferably, the external ports are randomly assigned.

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 [0001] The invention relates to the field of local area network port proxy, in particular to a local area network port proxy method of a port proxy server. Background technique [0002] Please refer to figure 1 In the prior art, external network access to the internal server needs to map the internal network service port to the gateway, and the external network PC accesses the application service through the WAN port IP of the gateway device plus the access port. When the internal server that needs to be accessed is connected under other gateway devices, that is, when it is used as a second-level or higher-level application service, if we want to access remotely, we need to map ports to the upper gateway device level by level. up to the topmost level. This mapping method is very cumbersome and time-consuming. If the external network is a dial-up Internet access method, the IP is changing at any time, and a domain name needs to be bound to the dial-up line ...
