Test system call function configures a port forwarding rule on DUT, and server ip is that DUT distributes to test system
The IP of system, is 8000 as the first port of outside port if being 80 as the second port of internal port；So first
Port rule is：80 ports of server ip will be forwarded to the bag of DUT WAN-side IP 8000 port requests, that is,
Say the internal port 80 for forwarding a packet to test system for asking the outside port 8000 of Devices to test.
After first port forwarding rule of configuration, DMZ host functions are then turned on, the DMZ IP of DMZ host functions are set
It is set to consistent with the inside IP of port forwarding function, therefore, the Article 2 port rule of setting is：By to DUT WAN-side IP's
The bag of arbitrary port request is forwarded to the corresponding ports of server ip, and the of DUT WAN-side IP first port and test system
Three ports are corresponding, i.e. DUT WAN-side first port is 8000, and the corresponding port of test system the 3rd is also 8000.Turn
During hair, the bag asked to DUT WAN-side IP port 8000 is forwarded to the port 8000 of corresponding test system.
After this good two rule of configuration, then only need to 80 ports and 8000 ports of snoopy test system, after test just may be used
Test result is obtained with situation about being arrived according to the two port snoops.
Step S200 in above-described embodiment 1, can be by calling nc orders at test system end to the 80 of test system
Port and 8000 ports are monitored.
