I had tried to run tshark in a centos 7 instance hosted in google cloud platform. When we analyze the captured packets, it is only showing the internal IP of that server. Is there any way to get the external IP( We have a reserved public IP setup for the instance) while capturing packets in tshark.
Following is the command I tried:
sudo tshark -i eth0 -f 'host 121.120.1xx.2xx' -w /tmp/capture.pcap
