An administrator added the following Ipsec VPN to a FortiGate configuration:
configvpn ipsec phasel -interface
set type dynamic
set interface "portl"
set mode main
set psksecret ENC LCVkCiK2E2PhVUzZe
config vpn ipsec phase2-interface
set phasel name "RemoteSite"
set proposal 3des-sha256
However, the phase 1 negotiation is failing. The administrator executed the IKF real time debug while attempting the Ipsec connection. The output is shown in the exhibit.
What is causing the IPsec problem in the phase 1 ?
