Port numbers in the translation table are used to map traffic from one source to another. This is necessary when using both NAT and PAT, because they are two different types of network address translations. When a packet comes in with a particular source address and port, the router needs to be able to determine which internal host and port it should be sent to. The port numbers in the translation table allow the router to do this mapping correctly.
