Set port ing to allow Internet access to the Intranet web

Author; Cai Dao Wang Liu

I am bored recently. I want to make my unit computer a web server, but the unit is shared with an adsl instance. I cannot directly access it according to the online saying.
Well, we share an adsl with another department. They ask external network companies to make the network. It should be safe.
But when I access 10.0.0.138, the configuration page of Alcatel does not have a password.
Check the information and find that using port ing allows the Internet to access my computer on the Intranet.
Specific Setting Process
Step 1 select the Advanced Configuration NAPT on the configuration page of Alcatel and click Add

Step 2 select the communication protocol in the newly added topic, which is generally tcp
Enter your internal ip address in the Intranet. For example, if Alcatel is 10.0.0. ×, the internal port is the port of your web server. For example, if tomcat is used, the port is set to 8080.
The external ip address of the next row is not moved by default. The external port is filled in the same way as the internal port. After all input is complete, click Apply.
This completes port ing,



Do not forget the last step of step 3. Click Save all settings in the upper left corner.


In this way, all your port ing is completed. It is worth noting that after this setting, only the external network can access your intranet machine through the IP address assigned by the isp, this ip address cannot be used to access the Intranet.
