The method of using port to map open intranet without gateway

Today to tell you how to use the port mapping, not through the Gateway Open intranet method.

First, the use of the premise

Need to have a public network of IP. If we now have a public network of P, 210.210.21.21

Second, the use of tools

1.lcx.exe

2.vdic

Three, method explanation

Method one, using Lcx.exe to map

(1) We will upload the Lcx.exe to the public network IP, in the public IP on the DOS environment in the implementation of Lcx–listen Port 1 Port 2

such as Lcx–listen 3030 3166

This command means listening on 3030-port and 3166-port to connect to the outside.

(2) Download the Lcx.exe to the computer in the intranet to be opened, then execute Lcx–slave IP Port intranet IP port in DOS environment

such as Lcx-slave 211.211.21.21 3030 172.16.32.153 80

To explain, the meaning of this sentence is that the intranet computer IP as 172.16.32.153 80 port (that is, Web service port)

Map to the public network IP for the 210.210.21.21 3030 port, so that the intranet and the public network of computers to establish a connection. If you

Intranet computer provides Web services, now, as long as through the extranet IP 210.210.21.21 and port 3166 can access the intranet site.

Before opening IP, Access address HTTP,//172.16.32.153/index.htm

After opening IP, Access address HTTP,//210.210.21.21, 3166/index.htm

Method two, use VIDC

We will upload the Vidcs.exe to the public network IP, on the public network computer running Vidcs–p port, such as vdics–p5205

On the public network computer listening to port 5205 and then back to the intranet computer, direct click to run VIDCc.exe

Explain the above settings, VIDC service IP, refers to the operation of the Vidcs.exe to monitor the IP address of the port, the port refers to the public network listening on the port, the above I monitor is 5205 ports, Bindip refers to the intranet you want to open the IP, Bind port refers to your intranet computers need open ports (FTP server port, WEB service port, mail Service port 25) If you want to open whichever you like.

The mapping port refers to which port you want to provide services through the public network. The port is determined by you, after filling, we point "connection", immediately to receive the prompt success to connect (210.210.21.21, 5205,ver, 1.2), indicating successful connection. Continue to point "bind" and you will also receive a prompt for success.

In this way, your 80 port on the machine is open. Access method HTTP,//public IP, mapping port.

such as HTTP,//210.210.210.210, 8080

The above is two ways to open the intranet without gateways.
