NO PING between ipsec interfaces

  • this article has some info, but as the tunnel is up it feels you want to look a step further:

    a packet capture showing the traffic enters the tunnel would be best. if it does then it might be the other end (FortiGate) which doesn't respond for some reason. a capture on that side would also be useful to check if it arrives.
