I have a FG140D-POE and I have a virtual switch for my camaras. In it I have a PC that monitores the camaras from all my sites. For some reason routing to the other sites stops working for that PC until I restart the PC and then when it reboot I can browse my sites. When it is not working I can still browse the camaras on the local network just not the other sites.
This is strange behaviour as restarting the PC should have nothing to do with what is happening on the FortiGate (which is presumably responsible for routing between sites).
When your PC stops routing to other sites, are you able to ping the default gateway IP address? Again I assume this is the FortiGate's IP address. I wonder if there's an issue where ARP or some other mechanism is breaking for the FGT.
