INTROUCTION
IP Share device is designed for IP address simplification and conservation, as it enables
private IP Internet works that use non-registered IP addresses to connect to the Internet. It
usually connects two networks together, and translates the private (not globally unique)
addresses in the internal network into single legal address before packets are forwarded onto
another network. Therefore, only one IP address is needed for the entire network to the
outside world. This provides additional security, effectively hiding the entire internal network
from the world behind that address.
