The first description of our configuration file, are similar format, if the intranet is 192.168.0.3, the extranet is 123.123.123.123, the configuration file is as follows: $db [' salver '] [' hostname '] = ' 192.168.0.3:3306 ';$db [' salver '] [' hostname '] = ' 123.123.123.123:3306 '; This time is the external network is the state of the annotation.

In the development, sometimes we need to send remotely, or through 3G and 4G, or other WiFi environment to send a small amount of data, and do not want to spend so much cost to develop a cloud server, this time the emergence of a router to expose an intranet IP for external network access. In fact, the implementation name of this method is called port mapping . Next we implement this way ready you want to expose the

Many programs in the local area network can be applicable, but between the external network and intranet and between intranet and intranet is not feasible.

The author of the school through ADSL set up routes to share the Internet. The extranet gateway and DNS are 10.0.0.138, the external network port IP address is 10.0 0.1, and the subnet mask is 255.255.255.0. Self-built sites are placed on the server, on the server has been IIS is installed and set up, and the "Default Web site" IP address points to 10.0.0.1. In the default state, you can access the extranet, but you cannot access the intranet. If yo
