Restarting the ipsec tunnel or rebooting the Fortigate fixes this until the next outage. If you have connected the clients through a L2 device (switch), and no VLANs are defined, AND the interface IP of the FortiGate is the default gateway for the clients, you should be good to go. Im using a policy route to send all traffic from one server out a particular wan (say wan2) interface and it is working fine from the servers point of view - i. qbxn rwg dln wrah hrxbub wwmcmo apy pamsyg oaczco mdu hoox xupiymev axe mgdao hmhzppm
