What does NAT type and NAT filter type mean?

“NAT type” describes how outgoing packets are modified depending on destination, possible values are:



-1 : NAT type is unknown (probe packets are probably being blocked).

1 : No NAT device detected.

2 : Source IP/port is always the same no matter the destination.

3 : Source IP/port differ depending on destination IP.

4 : Source IP/port differ depending on destination IP and port.



“NAT filter” values are:

-1 : NAT type is unknown (probe packets are probably being blocked).

1 : No NAT device detected.

2 : Any source IP/port can send packets to my public IP and it will end up at this computer (port forwarding, DMZ or similar scenario).

3 : Only replies to outgoing packets may be received, as long as the reply source IP matches the request destination IP.

4 : Only replies to outgoing packets may be received, as long as the reply source IP and port matches the request destination IP and port. - Select the version that matches your operating system.- Locate the downloaded tool, extract and run.- Once started, the user is asked to press the ENTER-key to start the test.
