•Configurable Ports: Any configurable port can be configured to be a WAN,
DMZ, or LA N port. By default, al l configurab le ports are set to be LAN ports.
Only one configurable port can be configured as a WAN port at a time (See
Configuring the WAN, page122). Up to four configurable ports can be
configured as DMZ ports (see Configuring DMZ, page141).
•Wireless Network (for ISA550W and ISA570W only): ISA550W and
ISA570W are configured with four SSIDs. All SSIDs are disabled by default.
For security purposes, we strongly recommend that you configure the
SSIDs with the appropriate security settings. See Wireless (for ISA550W
and ISA570W only), page 206.
•Administrative Access: You can access the Configuration Utility by using a
web browser from the LAN side and entering the default LAN IP address of
192.168.75.1. You can log on by entering the username (cisco) and
password (cisco) of the default administrator account. To prevent
unauthorized access, you must immediately change the administrator
password at the first login and are encouraged to change the username for
the default administrator account. See Changing the Default Administrator
Password, pa ge 32.
•Security Services: By default, the security services such as Intrusion
Prevention (IPS), Anti-Virus, Application Control, Web URL Filtering, Web
Reputation Filtering, and Spam Filter are disabled. See Chapter 7,
"Security Services."
•Firewall: By default, the firewall prevents inbound traffic and allows all
outbound traffic. If you want to allow some inbound traffic or prevent some
outbound traffic, you must customize firewall rules. Up to 100 custom
firewall rules can be configured on the security appliance. See Configuring
Firewall Rules to Control Inbound and Outbound Traffic, page252.
•VPN: By default, the VPN feature is disabled. The security appliance can
function as an IPsec VPN server, a Teleworker VPN client, or as a SSL VPN
gateway so that remote users can securely access the corporate network
resources over the VPN tunnels. You can also establish a secure IPsec VPN
tunnel between two sites that are physically separated by using the
Site-to-Site VPN feature. See VPN, page333.
