incorrect results, the FortiGate unit cannot connect to the Internet from its management
IP address. Check the FortiGate unit's default route to make sure it is correct. Check your
Internet firewall to make sure it allows connections from the FortiGate management IP
address to the Internet.
First, check the License Information dashboard widget to make sure the status of all
FortiGuard services matches the services that you have purchased. The FortiGate unit
connects to the FortiGuard network to obtain this information.
Go to System > Config > FortiGuard. Open web filtering and email options and select
Test Availability. After a minute, the GUI should indicate a successful connection.
12. Check the FortiGate bridge table.
The bridge table is a list of MAC addresses of devices on the same network as the FortiGate
unit and the FortiGate interfaces from which each MAC address was found. The FortiGate
unit uses this table to determine where to forward a packet. If a the MAC address of a
specific device is getting added to the bridge table, then packets to that MAC address will
be blocked. This may appear as traffic going to a MAC address but no reply traffic coming
back. In this situation, check the bridge table to ensure the correct MAC addresses have
been added to the bridge table. Use the following CLI command to check the bridge table:.
diagnose netlink brctl name host root.b
show bridge control interface root.b host.
fdb: size=2048, used=25, num=25, depth=1
Bridge root.b host table

If your device's MAC address is not listed, the FortiGate unit cannot find the device on the
network. This could indicate that the device is not connected or not operating. Check the
device's network connections and make sure it is operating correctly.
