摘要：
A method for translating network addresses includes receiving a first network packet, the first network packet comprising an internal source address. The method also includes generating, by performing a mapping operation, a mapping value. The generating of the mapping value uses, at least in part, at least a portion of the internal source address, and at least a portion of an external source address. The external source address is associated with the internal source address. The method also includes forwarding, using a second network packet, at least a portion of the first network packet. The second network packet comprises the external source address and at least a portion of the mapping value.
