Which MikroTik command deletes a firewall filter rule by its list number?

• A. /ip firewall filter remove numbers=<number>
• B. /ip firewall filter disable numbers=<number>
• C. /ip firewall filter print numbers
• D. /ip firewall filter remove

Answer: (A)

The command to delete a firewall filter rule by its list number uses the remove action with the numbers parameter. When you print the rules, each one gets a numeric index (its list number). By giving that index to remove, you target exactly that rule and delete it from the list. This is the direct way to remove a specific rule without affecting others. Disabling a rule also uses the numbers parameter, but it only deactivates the rule while keeping it in place. Printing just shows the rules and their numbers without changing anything. Using remove without specifying numbers wouldn’t target a rule by its list position (it would require a separate identifier), so it wouldn’t accomplish deleting by the list number.
