The internal segment of the network is where your servers, workstations, and printers live. The firewall is the point where information travelling between the two segments is checked for authenticity. Communication across the firewall is strictly one way unless more complex configurations are requested. No computers outside the protected segment may send packets inside unless the information is requested from behind the firewall. Further security is provided using Network Address Translation , which hides the address of the internal computers from their destination on the Internet.
