Cisco SA 500 Series Security Appliances Administration Guide
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
• 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
page 92.
• 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
1: Basic Network Configuration with Internet Access, page
• 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
Internet Access, page
• 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
Internet Access, page 28
Services, page
• 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.
