This configuration scenario builds on the basic system configuration scenario and steps through the process of configuring the system as a basic Internet gateway. The goal of the Internet gateway scenario is for the system to provide the following:

• Ability to route traffic between the office LAN and the Internet
• Ability to access the system from the local network by using SSH
• DHCP capability for providing dynamic IP addresses to internal devices
• NAT capability for translating multiple internal addresses to a single external address
• Firewall capability for preventing system access from the Internet
