防火墙技术——pix中的七个命令

领测软件测试网

　　 
　　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]
