textarea=The majority of firewalls available on the market today allow Network Address Translation, or NAT, to be implemented. NAT is a software application that allows a single IP address to represent a group of computers. When NAT receives a data packet from the internal network, it is repackaged and a new IP address is added before it is sent out to the external network. This technology provides an advantage in security, because the internal IP address is not used in the transmission. Since the data was repackaged and assigned a new IP address, attackers cannot identify the originating network.
