PF-60D IPSEC tunnel SA error

khamamo

Hello Everyone,

I am trying to build an IPSEC tunnel between my pfsense fw and a fortigate 60D fw but it is not working and I have a hard time to understand the reason behind that.

Logs in PF showing that there showing an invalid SA (always checkout in this phase). and i checked everything related to SA and couldn't find any mismatch.

I tried to build another tunnel with Juniper SSG20 with same result except SSG20 logs didn't show any logs from the tunnel, it is like it is a ghost :o

Attached the ph1, ph2, logs config for pf side. Also attached logs of 60D and below the configs.

        set psksecret ENC xxxx

end

Can anyone at least guide me to the right location for the material regarding IPSEC troubleshooting in PFSENSE

Set the log options as described there and see if you can initiate from the Fortigate side. Even if it doesn't work, the logs will be much more useful in that direction.

Odds are you have a P1 or P2 mismatch
