/!\ NOTE /!\ : this leaktest doesn't work on all computer due to the fact that it is coded against a specific language (that means that the program is looking at patterns on his native language), this is why for instance it won't work on french computers.
As a workaround, you must edit the source to make it fits with you computer.
For i was able to test it on my computer, i had to "hard codded" my MAC adress in it among other things, the leaktests features wasn't alteared and it still bypass sucessfully firewall sending 8 packets to my sniffer.

Leaktest description

Like "OutBound" leaktest, MBtest send directly to the NIC his packets to try to bypass firewall. To do this, it sends differents kind of packet of different size/protocoles/type. It uses Winpcap libraries, but this isn't need to be installed by the user as it is the case for this leaktest, in theory the program could copy needed files (just two in fact) by itself without to reboot.

Meaning

If the test is a success, this means that your firewall is stuck in high level network and doesn't check low level.
