Firewall

Bug ID

On the Policy & Objects > Traffic Shaping page, when deleting or creating a shaper, the counters for the other shapers are cleared.

1007566

When the FortiGate has thousands of addresses and hundreds address groups, the GUI can take a few minutes to search for a specific address inside the address group dialog.

Workaround: User can create the address group in the CLI instead by using the exact address name. User can also perform a search in the CLI using a partial match. For example:

config firewall addrgrp
    edit address_group
        set member <pattern>?
    next
end

1057080

On the Firewall Policy page, search results do not display in an expanded format.

FortiGate 6000 and 7000 platforms

Bug ID

Description

790464

After a failover, ARP entries are removed from all slots when an ARP query of single slot does not respond.

994241

On FortiGate 7000F using FGSP and FGCP, when TCP traffic takes an asymmetric path, the TCP ACK and data packets might be dropped in NP7.

997161

On FortiGate 6000 FPCs and FortiGate 7000 FPMs the node process may consume large amounts of CPU resources, possibly affecting FPC or FPM performance. (You can run the diagnose sys top command from an FPC or FPM CLI to view CPU usage.) This problem may be caused by security rating result submission.

Workaround: Use the following commands to disable automatic security rating results submission and to disable running scheduled security ratings checks:

config system global
    set security-rating-result-submission disable
    set security-rating-run-on-schedule disable
end

Once you have entered these commands, use the following command to restart the node process:

diagnose nodejs process restart

        unset inbandwidth
        unset outbandwidth
    next
end

1020921

When configuring an SNMP trusted host that matches the management Admin trusted host subnet, the GUI may give an incorrect warning that the current SNMP trusted host does not match. This is purely a GUI display issue and does not impact the actual SNMP traffic.
