In sum, i can't analyze traffic from my own interfaces to my own interfaces.
even if it is not 127.0.0.1

(cause if you ping your ethernet IP, the packet doesnt leave your ethernet
card). It's in fact another loopback.

What a crap. And only in windows? the problem is then winpcap? man, i dont
know how this framework
doesnt allow loopback capturing. it's ridiculous.

see you.
