Here is the partial output of the inetstatShow command:

21453d8 TCP    0   0 10.10.10.10:80     10.1.1.1:1244   TIME_WAIT

2144f34 TCP    0   0 10.10.10.10:80     10.1.1.1:1238   TIME_WAIT

2144eb0 TCP    0   0 10.10.10.10:1080   10.1.1.1:1224   ESTABLISHED −−− ISP assigned address

This output shows no evidence of this address. The output shows the public address that the ISP uses, which is
evidence of a Traditional NAT scenario.

In order to identify Bi−directional NAT and Twice NAT, you need a sniffer trace from the same network
segment as the CTC workstation. Ideally, a sniffer that runs on the CTC workstation is most suitable.
