CISCO PIX Firewall Installation process

The Cisco PIX Firewall installation process is as follows:

1. The PIX will be placed to the rack, after the detection of the power system connected to the power supply, and power on the host.

2. Connect the console port to the PC's serial port and run the HyperTerminal program from the console port into the PIX system; the system prompts pixfirewall>.

3. Input command: Enable, enter privileged mode, at this time the system prompts for pixfirewall#.

4. Input command: Configure terminal, initialize the system.

5. Configure the Ethernet port parameters:

Interface ethernet0 Auto (auto option indicates system Adaptive network card type)

Interface Ethernet1 Auto

6. Configure the IP address of the internal and external network adapter:

IP address inside IP_Address netmask

IP address outside ip_address netmask

7. Specify the external address range:

Global 1 Ip_address-ip_address

8. Specify the internal address to be converted:

Nat 1 IP_Address netmask

9. Set the default route to the internal and external networks

Route inside 0 0 inside_default_router_ip_address

Route outside 0 0 outside_default_router_ip_address

10. Configure static IP address mappings:

Static outside IP_Address inside IP_Address

11. Set some control options:

Conduit GLOBAL_IP Port[-port] Protocol foreign_ip [netmask]

Global_ip refers to the address to be controlled.

Port refers to the ports that are acting, where 0 represents all ports

Protocol refers to the connection protocol, such as: TCP, UDP, etc.

FOREIGN_IP represents an access to GLOBAL_IP's external IP, which represents all IP.

12. Set Telnet options:

Telnet local_ip [netmask]

LOCAL_IP indicates that the IP address of the PIX is allowed to be accessed via Telnet (if not set, the PIX configuration can only be performed by the Consle).

13. Save the configuration:

WR Mem

14. Several commonly used network test commands:

#ping

#show Interface View port status

View static address mappings #show statics
