A private network uses a NAPT device at public IP address 128.100.116.1 The computers in the network use addresses of the form 10.0.0.x/22. Suppose that computer inside the NATed network sends a request with

Source address: 10.0.0.4

Source port: 932

Destination address: 108.155.105.30

Destination port: 22

The next available port number on the NAPT device is 12000

**Possible answers are only:

-> 22

-> 10.0.0.4

-> 108.155.105.30

-> 932

-> 12000

-> 128.100.116.1
