2. Configure a port mapping. | Configure a general port mapping:port-mapping application application-name port port-number [ protocol protocol-name ] Configure an ACL-based host-port mapping:port-mapping application application-name port port-number [ protocol protocol-name ] acl [ ipv6 ] acl-number Configure a subnet-based host-port mapping:port-mapping application application-name port port-number [ protocol protocol-name ] subnet { ip ipv4-address { mask-length | mask } | ipv6 ipv6-address prefix-length } [ vpn-instance vpn-instance-name ] Configure an IP address-based host-port mapping:port-mapping application application-name port port-number [ protocol protocol-name ] host { ip | ipv6 } start-ip-address [ end-ip-address ] [ vpn-instance vpn- instance-name ]
| By default, all application protocols map with well-known ports. You can configure these commands together. APR selects a port mapping to recognize the application protocol of a packet in the following order: IP address-based port mapping. Subnet-based port mapping. ACL-based host-port mapping. General port mapping.
For the same type of mappings, the port mapping with a transport layer protocol has higher priority than the mapping without a transport layer protocol. If the specified application protocol does not exist, the system first creates the protocol. |
