A Firewall hides information about the network by making it seem that all outgoing traffic originates from the firewall rather than the network.
How does this feature help in securing a network ???

The idea is that you don't allow hackers to see the ip address of a specific machine in your network that they can then attack. Funneling internet trafic through the firewall presents a single, secure entry / exit point for your lan.
