Scenario 1: Basic Network Configuration with Internet
Access
Internet
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.
Before you configure your network, make sure that you have upgraded the
firmware (see Upgrading the Firmware, page
Administrator password (see
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
