Hello, I need to use Virtual Router with a 3G USB Modem or a WiMAX USB Modem.  Does anyone know how to do this.  

I want my internet source to use the USB Modem and others around me can use my Internal WiFi to benefit from the USB Modem.

I found that any device that you want to use an internet source needs to be installed before installing the virtual router software.  i.e.  re-install virtual router when your USB modem is active
