| PCs, but overloads your Internet connection so you can not | |
| use it - the service is unavailable. | |
| ∙ This device uses "Stateful Inspection" technology. This | |
| system can detect situations where individual TCP/IP pack- | |
| ets are valid, but collectively they become a DoS attack. | |
Threshold | This setting affects the number of | |

| tacts the Server with a connection request, but then does not | |
| reply to the Server's response. | |
| ∙ While the optimum number of | |
| allowed (the "Threshold") depends on many factors, the | |
