B Explanation: When user attempts sending VPN traffic, he sees SmartView Tracker error message: “Phase one received notification from peer; payload malformed”

Solution ID: sk36718
Product: IPSec VPN, SmartView Tracker
Version: NGX R65, R70, R71, R75, R76, R77, R77.10, R77.20

Symptoms

When user attempts sending VPN traffic, he sees SmartView Tracker error message: “Phase one received notification from peer; payload malformed”.
In IKE debug, phase 1 gets to packet 5. There is no packet 6. Since the remote peer has initiated the tunnel, an INFO packet is sent to the remote peer after packet 5 stating PAYLOAD-MALFORMED.

Cause

A common cause is that the pre-shared secret is not configured correctly on both peers.
