Setting up Port redirection on Vigor Router
The Port Redirection used access internal servers from the Internet. Internet hosts use the WAN IP address of the router to access internal network services. For example a web server you may be hosting locally. Requests from the Internet are mapped to the private IP address/port of the internal server.
Note: Port redirection only applies to incoming traffic
You can forward a different external port to the port of your internal Server/PC. This allows you to have more than one internal server using the same port number.
This video shows you how to configure a DrayTek Vigor router so that a web server and a VNC server hosted on the local LAN so that they can be accessed from the Internet. The example uses a DrayTek Vigor2860 but the same procedure can be used for other DrayTek router models.
