You can add only one network packet rule at a time.
To add a network packet rule, execute the following command:
kics-control -F --add-rule --name <
rule name
> --action <
action
> --protocol <
protocol
> --direction <
direction
> --remote <
remote address
> --local <
local address
> --at <

setting lets you specify the index of the created rule in the list of network packet rules. If the --at
setting is not specified or its value is larger than the number of rules in the list, the new rule is added to the end of the list.
