Firewall Filter Configuration > Configuring Firewall Filters

To configure firewall filters, include the firewall statement at the [edit] hierarchy level:

[edit]

firewall {

    family family-name {

        filter filter-name {

            accounting-profile name; 

            interface-specific; 

            term term-name {

                from {

                    match-conditions;

                }

                then {

                    action; 

                    action-modifiers; 

                }

            }

        }

    }

}

   
NOTE: You can specify IP version 4 (IPv4) filters at either the [edit firewall] hierarchy level or the [edit firewall family inet] hierarchy level.
