Fortigate 80E disconnection internet
I'm a newbie, I'm using fortigate 80E with OS level 6.4.3 version. I've been disconnected internet on firewall recently. I can't ping ip wan from external and internal as well. I must reboot firewall to resolve the issue. I don't know why and how to fix it. There are 2 line WAN to load balance. Please help me how to fix permanent this issue. I wonder whether this is related to firmware or not. Where is to check log ? Many thanks for helping me.
