To continue this discussion, please ask a new question. The ESP packet invalid error is due to an encryption key mismatch after a VPN tunnel has been established. The FortiGate must be connected to the Internet in order to automatically connect to the FortiGuard Distribution Network (FDN) to validate the license and download FDN updates. Administrators may also see the following when running IKE debugs (diag debug app ike -1) while these logs are occurring: The Security Parameter Index (SPI) is a value that is sent with every ESP packet, and is used as a means of matching incoming ESP packets to the correct IPsec tunnel on the VPN endpoint. set phase1name "HotelToPats" 04-17-2007 However when I tried to ping on either side, I got " Invalid SPI" error in the Foriwifi VPN log. The following are some examples of how this might occur: - The VPN gateway or client performs a re-key for this IPsec tunnel (as defined in the VPN Phase 2 settings), and the other endpoint fails to synchronize with this change for some reason. In addition, you can add the command "crypto isakmp invalid-spi-recovery" to the global configuration of the routes. leftsubnet=192.168.0.0/24 02:25 PM, Created on Compatibility This integration has been tested against FortiOS version 6.0.x and 6.2.x. stat: rxp=0 txp=0 rxb=0 txb=0 set proposal 3des-sha1 07-22-2013 FGT and Openswan? edit 28 Phase I: Hi emnoc, name=Jason ver=1 serial=2 0.0.0.0:0->175.*.*. - In some scenarios, it's possible that a random host on the Internet is simply sending ESP packets to the FortiGate's public IP, even if a VPN tunnel had not been established between this remote peer and the FortiGate beforehand. This will make the routers notify one another when receiving this error - which should start the syncing process automatically. set srcintf "wan1" - edited The Phase 1 parameters identify the remote peer or clients and supports authentication through preshared keys or digital certificates.

What does your diag pvn tunnel show ? As well, the SPI itself is visible when examining the ESP packet in a tool like Wireshark: With that in mind, an administrator could run a packet capture on the FortiGate interface receiving these unknown SPIs, then compare against the current IPsec tunnel list to confirm if the Source/Destination IP addresses and the observed SPIs are correct or not.
