Just to name a few: |
| 13 |
-permitting certain services for certain hosts (ip/mac based) |
| 14 |
-time/cpu-load based restriction on certain services |
| 15 |
-filtering malformed/fragmented packets |
| 16 |
-implementing port-knocking feature |
| 17 |
-statistical evaluation of traffic (ip/protocol/service based) |
| 18 |
etc. |

All of the above mentioned is probably possible to do using |
| 21 |
different method, but why not use iptables for it? |
