I was testing esp-null as configured in a transform-set in IOS under the impression that the payload will not be encrypted however I am unable to view the payload in clear-text.
I just wanted to know if payload can be seen in clear-text since esp-null does not perform encryption. An example would be of good help. TIA
you are right with the assumption that with esp-null, the payload will be in clear-text. How do you try to look at that cleartext?
I am looking at the pcap capture between the two VPN devices but I am unable to see the type of traffic underneath those ESP packets. I'm not sure if it was just the config or something else beyond my comprehension. Thanks!
Did you tell Wireshark to decode ESP-null packets? This option is found under Preferenes -> Protocols -> ESP.
