Bug ID |
Description |

On the Policy & Objects > Firewall Policy page in 6.4.0 onwards, the IPv4 and IPv6 policy tables are combined but the custom section name (global label) is not automatically checked for duplicates. If there is a duplicate custom section name, the policy list may show empty for that section. This is a display issue only and does not impact policy traffic. Workaround: rename the custom section to unique name between IPv4 and IPv6 policies. |

Within the Policy & Objects menu, the firewall, DoS, and traffic shaping policy pages take around five seconds to load when the FortiGate cannot reach the FortiGuard DNS servers. Workaround: set the DNS server to the FortiGuard DNS server. |

If the first firewall service object in the service list (based on the order in the command line table) has a protocol type of IP, the GUI may incorrectly modify its protocol number whenever a new firewall service of the same protocol type IP is created in the GUI. This silent misconfiguration can result in unexpected behavior of firewall policies that use the impacted service. For example, some 6K and 7K platforms have firewall service ALL (protocol type IP) as the first service, and this can cause the ALL service to be modified unexpectedly. Workaround: create a new service in the CLI, or move a non-IP type services to the top of the firewall service list. For example, if config firewall service custom
edit "unused"
set tcp-portrange 1
next
move "unused" before "ALL"
end
