Technical Tip: Cannot configure negate features under local-in-policy setting in FortiGate unit

[caunon]

Description	This article describes some situations, where it needs to configure negate feature to restrict accessing or restrict the packets like srcaddr-negate, dstaddr-negate, or service-negate under the local-in-policy setting in the FortiGate unit.
Scope	FortiGate.
Solution	When configuring 'negate' features under local-in-policy settings like srcaddr-negate, dstaddr-negate, or service-negate, it shows the error message as below. FGT # config firewall local-in-policy FGT (local-in-policy) # edit 1 new entry '1' added FGT (1) # set srcaddr-negate enable command parse error before 'srcaddr-negate' Command fail. Return code -61 FGT (1) # To fix that, it is necessary to upgrade the firmware version of the FortiGate unit to v7.0.x and above. Then it will be able to configure srcaddr-negate, dstaddr-negate, or service-negate under local-in-policy after that. FGT # config firewall local-in-policy FGT (local-in-policy) # edit 1 new entry '1' added FGT (1) # set srcaddr-negate enable FGT (1) # set dstaddr-negate enable FGT (1) # set service-negate enable FGT (1) # set intf port1 FGT (1) # set srcaddr FABRIC_DEVICE FGT (1) # set dstaddr FABRIC_DEVICE FGT (1) # set service ALL_TCP FGT (1) # set schedule always FGT (1) # end FGT # Note: Starting from v7.6.0, the Local-in-Policy can now also be configured in the GUI.
