| Description: |
| add or remove iptables rule to DROP (default) packets from |

| Usage: |
| * specify action ('add' or 'remove') |

| delete that specific rule. |
| * specify the ip to block |
| * specify the destination port to block (defaults to all ports) |
| * optional packet type to block (default tcp) |
| * optional iptables rule (default DROP) |
| * optional direction to block (default 'INPUT') |
| * States boolean toggles adding all supported tcp states to the |
| firewall rule |
| Returns: |
