六个基本命令

　　static:Configure a persistent one-to-one address translation rule by mapping a local IP address to a global IP address. This is also known as Static Port Address Translation (Static PAT). (Configuration mode.)

　　static [(prenat_interface, postnat_interface)] {mapped_address| interface} real_address [dns] [netmask mask] [norandomseq]

　　[connection_limit [em_limit]]

　　show static

　　nameif,Name interfaces and assign security level. (Configuration mode.)

　　nameif hardware_id if_name security_level

　　show nameif /clear nameif

　　interface：Identify network interface speed and duplex. (Configuration mode.)

　　interface hardware_id [hardware_speed] [shutdown]

　　show interface hardware_id [hardware_speed] [shutdown]

　　ip address：Identifies addresses for network interfaces, and enables you to set the number of times the PIX Firewall will

　　poll for DHCP information. (Configuration mode.)

　　ip address if_name ip_address [netmask]

　　ip address outside dhcp [setroute] [retry retry_cnt]

　　ip address if_name pppoe [setroute]

　　ip address if_name ip_address netmask pppoe [setroute]

　　show ip

　　Displays IP addresses assigned to the network interfaces.

　　show ip address if_name dhcp

　　Displays detailed information about the DHCP lease.

　　show ip address if_name pppoe

　　Displays detailed information about the PPPOE connection.

　　global：Create or delete entries from a pool of global addresses. (Configuration mode.)

　　global [(if_name)] nat_id {global_ip [-global_ip] [netmask global_mask]} | interface

　　global [(if_name)] nat_id {{global_ip} [netmask global_mask] | interface}

　　show global

　　nat:Associate a network with a pool of global IP addresses. (Configuration mode.)

　　nat [(if_name)] id address [netmask [outside] [dns] [norandomseq] [timeout hh:mm:ss] [conn_limit [em_limit]]]

　　nat [(if_name)] 0 access-list acl_name

　　show nat

　　route

　　Enter a static or default route for the specified interface. (Configuration mode.)

　　route if_name ip_address netmask gateway_ip [metric]

　　show route

　　conduit..

　　联合使用static和conduit命令来只允许http访问。

　　pixfirewall(config)#static (inside,outside) 192.168.1.101 10.0.1.10 netmask 255.255.255.255

　　pixfirewall(config)#conduit per tcp any eq www host 172.16.1.1

　　conduit语法；

　　conduit deny|permit protocol | object-group protocol_obj_grp_id global_ip global_mask | object-group network_obj_grp_id

　　[operator port [port] | object-group service_obj_grp_id] foreign_ip foreign_mask | object-group network_obj_grp_id [operator

　　port [port] | object-group service_obj_grp_id]
