Chapter 7 Firewall : Firewall objects : Virtual IPs : Creating a Virtual IP : Example
  
Example
This example is for a VIP that is being used to direct traffic from the external IP address to a webserver on the internal network.The webserver is for company use only. The company’s public facing webserver already used port 80 and there is only one IP external IP address so the traffic for this server is being listened for on port 8080 of the external interface and being sent to port 80 on the internal host.
