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]
