Hi all, we have an IPsec VPN to a client network and have forgotten (not documented yet) the PSK of the Phase 1 of VPN. How can I get the unencrypted value of PSK?

    sorry, you don' t need a sniffer if you' ve admin passwd in FTG-box CLI command " show vpn ipsec phase1 <your_tunnel_number> " shows to you pksecret in encrypted form but, if you' ve Fortinet admin pass and Forticlient access, all this remains an academic exercise change your PSK

    I know I can change the PSK. But in the other side our client is running FreeSwan and I cant' t manage it. I didn' t want to say it we have lost the PSK.
