i am trying to establish a site 2 site VPN with a remote office using sonicwall NSA3600.
i am using FG300D with firmwre 5.4.2.
from my side i can only see phase 1 connection "progress IPsec phase1" success.
the remote side is showing error "failed payload verification after decrpyption possible preshared key mismatch"
what should we do?
we followed the steps given in this fortinet KB to configure the VPN

hi,
"failed payload verification after decrpyption possible preshared key mismatch"-- care about to re-entry preshared key on both devices?

we have changed the preshared key on both end twice
managed to solve the issue after using a preshared key without going through key generator.

key generator of?
Fortigate Newbie
initially we used a key generator to create the encrypted preshared key but seems like it dont work after providing it to the other party to insert into the sonicwall FW.
so in the end we just use a password without encrpytion
glad to hear you figured it out
