IKE decryption with fragmented messages

0

Hi,

this Wireshark has a problem decrypting IKE messages when message 5 and 6 are fragmented and reassembled in Wireshark? I used the described method numerous times with OpenSwan and it worked like a charm. Then I changed to certificate based authentication and the payload exceeded the 1500 byte packet size. Although I enter ICOOKIE and enc_key as the times before, I still see only encrypted data... I will enable JUMBO frames to verify this but maybe you have seen this before...

Cheers, Dominik

Hi,
