  - intercept a session and replay it as many times you want to strictly test your application (number 10, 11, 12, 22, etc.)
  - verify if a router is well configured even if the needed computers are down (number 48, ..., 53, etc.)
  - check if your router/firewall/computer blocks
    - IP protocols (number 29, ..., 34, etc.)
    - IP options (number 29, ..., 34, 73, ..., 79, etc.), source routing (number 45, 56, 59, 62, etc.)
    - IP fragments (number 44, 55, 58, 61, 72, etc.)
