(1)     普通内部服务器

·     外网地址单一，未使用外网端口或外网端口单一

nat server [ protocol pro-type ] global { global-address | current-interface | interface interface-type interface-number } [ global-port ] [ vpn-instance global-vpn-instance-name ] inside local-address [ local-port ] [ vpn-instance local-vpn-instance-name ] [ acl { ipv4-acl-number | name ipv4-acl-name } ] [ reversible ] [ vrrp virtual-router-id ] [ rule rule-name ] [ disable ] [ counting ] [ description text ]

undo nat server [ protocol pro-type ] global { global-address | current-interface | interface interface-type interface-number } [ global-port ] [ vpn-instance global-vpn-instance-name ]

·     外网地址单一，外网端口连续

nat server protocol pro-type global { global-address | current-interface | interface interface-type interface-number } global-port1 global-port2 [ vpn-instance global-vpn-instance-name ] inside { { local-address | local-address1 local-address2 } local-port | local-address local-port1 local-port2 } [ vpn-instance local-vpn-instance-name ] [ acl { ipv4-acl-number | name ipv4-acl-name } ] [ vrrp virtual-router-id ] [ rule rule-name ] [ disable ] [ counting ] [ description text ]

undo nat server protocol pro-type global { global-address | current-interface | interface interface-type interface-number } global-port1 global-port2 [ vpn-instance global-vpn-instance-name ]

·     外网地址连续，未使用外网端口

nat server protocol pro-type global global-address1 global-address2 [ vpn-instance global-vpn-instance-name ] inside { local-address | local-address1 local-address2 } [ local-port ] [ vpn-instance local-vpn-instance-name ] [ acl { ipv4-acl-number | name ipv4-acl-name } ] [ vrrp virtual-router-id ] [ rule rule-name ] [ disable ] [ counting ] [ description text ]

undo nat server protocol pro-type global global-address1 global-address2 [ global-port ] [ vpn-instance global-vpn-instance-name ]

·     外网地址连续，外网端口单一

nat server protocol pro-type global global-address1 global-address2 global-port [ vpn-instance global-vpn-instance-name ] inside { local-address [ local-port1 local-port2 ] | [ local-address | local-address1 local-address2 ] [ local-port ] } [ vpn-instance local-vpn-instance-name ] [ acl { ipv4-acl-number | name ipv4-acl-name } ] [ vrrp virtual-router-id ] [ rule rule-name ] [ disable ] [ counting ] [ description text ]

undo nat server protocol pro-type global global-address1 global-address2 global-port [ vpn-instance global-vpn-instance-name ]

(2)     负载均衡内部服务器

nat server protocol pro-type global { { global-address | current-interface | interface interface-type interface-number } { global-port | global-port1 global-port2 } | global-address1 global-address2 global-port } [ vpn-instance global-vpn-instance-name ] inside server-group group-id [ vpn-instance local-vpn-instance-name ] [ acl { ipv4-acl-number | name ipv4-acl-name } ] [ vrrp virtual-router-id ] [ rule rule-name ] [ disable ] [ counting ] [ description text ]

undo nat server protocol pro-type global { { global-address | current-interface | interface interface-type interface-number } { global-port | global-port1 global-port2 } | global-address1 global-address2 global-port } [ vpn-instance global-vpn-instance-name ]

(3)     基于ACL的内部服务器

nat server global { ipv4-acl-number | name ipv4-acl-name } inside local-address [ local-port ] [ vpn-instance local-vpn-instance-name ] [ vrrp virtual-router-id ] [ rule rule-name ] [ priority priority ] [ disable ] [ counting ] [ description text ]
