About the Default Settings
About the Default Settings
The SA 500 Series Security Appliances are pre-configured with settings that allow you to start using the device with minimal changes needed. Depending on the requirements of your Internet Service Provider (ISP) and the needs of your business, you might need to modify some of these settings. You can use the Configuration Utility to customize all settings, as needed.
Settings of particular interest are described below. For a full list of all factory default settings, see Appendix D, “Factory Default Settings.”
• IPv4 Addressing: By default, the security appliance is in IPv4 Only mode. If
you want to use IPv6 addressing, first enable IPv6 mode and then configure your IPv6 WAN and your IPv6 LAN. See Configuring IPv6 Addressing,
page 92.
1
• WAN Configuration: By default, the security appliance is configured to
obtain an IP address from your ISP by using Dynamic Host Configuration Protocol (DHCP). If your ISP assigned a static IP address, you will need to configure it. In addition, if your ISP requires a login every time that you connect to the Internet, you will need to enter the account information. You can change other WAN settings as well. For more information, see Scenario
1: Basic Network Configuration with Internet Access, page 28.
• LAN Configuration: By default, the LAN interface acts as a DHCP server for
all connected devices. For most deployment scenarios, the default DHCP and TCP/IP settings of the security appliance should be satisfactory. However, you can change the subnet address, or the default IP address of the security appliance. You can assign static IP addresses to connected devices rather than allowing the security appliance to act as a DHCP server. For more information, see Scenario 1: Basic Network Configuration with
Internet Access, page 28.
• Optional Port: This port is preset to act as a secondary WAN port.
Alternatively, you can configure the Optional port for use as a DMZ port or an extra LAN port. See Scenario 1: Basic Network Configuration with
Internet Access, page 28 or Scenario 4: DMZ for Public Web Sites and Services, page 32.
• Wireless Network (SA 520W only): The SA 520W is configured with an
access point named AP1, which has the default network name of Cisco_1. The access point is enabled by default. The security profile has Open security and identifies itself to all wireless devices that are in range. These settings make it easy for you to begin using your wireless network.

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.
235234
NOTE Before you configure your network, make sure that you have upgraded the
firmware (see Upgrading the Firmware, page 26) and changed the default Administrator password (see Changing the Default User Name and Password,
page 25).
