Hi,
I remembered that pre shared key use for ISAKMP phase-1.
for authentication. Is that right? (ESP)

There are total six frames for main mode during phase 1
First two frames look easy to understand.
How about the third and fourth frame. What do they do in detail?
Can anyone give a little bit more detail operation?


TIA,
st
