Anti-DoS NAT (LAN to WAN) 4. Anti-DoS NAT (WAN to LAN) 5. BT+eMule Load Testing (five hours) Topology: Fortigate 60                                 |                    10/100Mbps 24Port Switch                   (WAN)   |          |                        P-330W       PC B                   (LAN)   |                            PC A 1) no Anti-DoS NAT (LAN to WAN) Methodology: DoS prevention is disabled. We send a large file (750MB) from PC A to PC B through the windows “My Network Places”. Result: (12.5MB=100Mbits) Highest: 6.39MB/s Average: 5.55MB/s Lowest: 2.89MB/s Comments: File transmission is not stable. The speed is various from 2.89MB/s to 6.39MB/s. However, it seems that the average throughput from LAN to WAN is 5MB/s, which is around 40Mb/s. 2) no Anti-DoS NAT (WAN to LAN) Methodology: DoS prevention is disabled. We send a large file (750MB) from PC B to PC A through the windows “My Network Places”. Result: (12.5MB=100Mbits) Highest: 5.89MB/s Average: 4.86MB/s Lowest: 200kB~ 1.5MB/s Comments: File transmission is not stable. The speed is various from 200KB/s to 5.89MB/s. However, it seems that the average throughput from WAN to LAN is 4.86MB/s, which is around 39Mb/s. As we can see here, the performance between WAN to LAN and LAN to WAN makes no significant difference. 3) Anti-DoS NAT (LAN to WAN) Methodology: DoS prevention is enabled. We send a large file (750MB) from PC A to PC B through the windows “My Network Places”. Result: (12.5MB=100Mbits) Highest: 2.81MB/s Average: 1.89MB/s Lowest: 586kB/s Comments: Again file transmission is not stable. The performance is greatly decreased when DOS prevention is enabled. Now the throughput is various from 586KB/s to 2.81MB/s. Average throughput from LAN to WAN dropped to 1.89MB/s, which is around 15Mb/s. 4) Anti-DoS NAT (WAN to LAN) Methodology: DoS prevention is enabled. We send a large file (750MB) from PC B to PC A through the windows “My Network Places”. Result: (12.5MB=100Mbits) Highest: 5.18MB/s Average: 4.46MB/s Lowest: 1.2MB/s Comments: It is strange that with the option of DoS prevention enabled. It should affect the throughput of “WAN to LAN” traffic, but not “LAN to WAN” traffic. However, result shows that throughput from WAN to LAN with DoS prevention enabled is much better than LAN to WAN under the same condition. Throughput of this test is various from 1.2MB/s to 5.18MB/s. Average throughput from WAN to LAN dropped to 4.46MB/s, which is around 36Mb/s. In conclusion, since the device that we tested is using a beta firmware, we should take the result as a reference, but not the actual performance that you will get when you buy one on the public market. Usually, when the firmware is final, you should get better performance but less bugs. 5) BT+eMule Load Testing Methodology: DoS prevention is enabled, we used BT v0.60 and eMule 0.46, with each protocols 5 tasks to download. According to the session screen of Fortigate, it showed the highest number of sessions is around 2853. Then this number will drop slowly. After five hours of continually running, the device does not have any abnormal behavior. Internet Web page access: Work and running, it looks like that the Web page respond time makes no difference under the P2P load testing. P-330W GUI: Work and running, unlike some of the old D-link model like DI-604 or DI-704, the web GUI of P-330W is responding normally under the five hours P2P load testing. PING testing: Normal, the respond time from pinging to 168.95.1.1 shows no significant incensement under the loading of P2P traffic. Temperature: Room temperature is 23C (73.4F) by the time we performed the test. After five hours of P2P downloading, the subjective feeling of the case is fairly warm. It is not hot at all.
