VirtualBox is an x86 virtualization software package. Throught VB I will create a virtual machive that it will run NorduGrid middlewar. Using the Ethernet bridging i will combine an ethernet interface with my  virtual interface and bridging them together under a single IP address. From now on I can have access to my machine throught internet by looking for it using it's public IP address.

Search in Synaptic Power Manager for VirtualBox.
