Getting Started Common Configuration Scenarios 1 Scenario 1: Basic Network Configuration with Internet Access 235234 Outside Network Private Network Laptop computer Internet Internet Access Device SA 500 Printer Personal computer In a basic deployment for a small business, the security appliance enables communication between the devices on the private network and also allows computers to access the Internet. With the default settings, the security appliance gets its WAN address dynamically from the ISP. All devices on the LAN receive their IP addresses dynamically from the security appliance. All devices have access to the Internet, but no inbound traffic is allowed from the Internet to any LAN devices. Configuration tasks for this scenario: The default configuration is sufficient for many small businesses, and you might not need to change any of the WAN or LAN settings. However, depending on the requirements of your ISP, as well your preferences for your LAN configuration, you can make changes, as needed. NOTE Before you configure your network, make sure that you have upgraded the firmware (see Upgrading the Firmware, page 24) and changed the default Administrator password (see Changing the Default User Name and Password, page 23). Consider the following first steps: 1. Review the WAN configuration and make any changes that are needed to set up your Internet connection. In the WAN & LAN Connectivity section of the Getting Started (Basic) page, click the WAN settings link. For more information, see Configuring the WAN Connection, page 37.
