摘要： A system for network address port translation. The system comprises a storage device and a translation module. The storage device stores a plurality of private address tables and a private port table, wherein each private address table and private port table comprises at least one entry, and each entry is assigned an index number. The translation module, connected to the storage device, receives a private IP address and a private port number, wherein the private IP address comprises a plurality of private address subsets, stores the private address subsets and private port number as entries in the private address tables and the private port table, respectively, and translates the private IP address and port number to and from a public port number, wherein the public port number comprises a plurality of public port subsets corresponding to the index numbers in the private address tables and the private port table.
