IPSEC VPN Between Fortigate And Cisco

[praveen_Dharmaraj]

Dear All ,

i created IPSEC VPN from FGT to CISCO (its a migration from checkpoint to FGT )

Encryption ,hashing , DH , Key life and pre share are all same as before .

Key exchage/Proposal exchange i can see after(ident_i3send)  am getting error :

Ignoring unencrypted PAYLOAD-MALFORMED message From -----(remote Gateway IP)

Thanks,

Praveen

Hello Praveen,

Check the VPN Client Phase 1 algorithms to be consistent with the gateway (or peer) Phase 1 algorithms. Check the IP address range. Check the Local and remote IDs. (You can specify those if there are multiple tunnels between the two) Note: the local ID on one site is the remote ID on the other site and conversely ! Check the PFS to be activated or not on both peers

Also verify the preshared key and try to avoid special characters.
