Finnaly, i found the problem. It wasn't connection problems or problems with code nor problem with win7 itself. it was some logical miss about routing methods.<br>sorry for disturbing you, it work well now.<br><br><div class="gmail_quote">

the deal is that the packets do not reach the physical link. something between winpcap -> ... -> physical link blocks it, some security filter, network driver or whatever else...and i want to know exactly where is the problem.<br>
anyone ever tried to inject packets on win7?<br>to avoid more questions:<br>all network preferences are ok, no physical problems. <br>the code is written right, it works on XP.</p><div><p class="MsoNormal">2010/7/1 Gianluca Varenni <<a href="mailto:gianluca.varenni@cacetech.com" target="_blank">gianluca.varenni@cacetech.com</a>></p>
