[Winpcap-users] packet sending on win7

[Gianluca Varenni]

What I asked is a direct connection between the two computers, not between the computer and the modem.

BTW, are you sure it's a DSL modem and not a DSL router?

Have a nice day

i already have that kind of connection.
win7 <-ethernet_cable-> adsl_modem

i can ping modem from cmd and i get reply, but when i send packet myself i dont get reply, i tried to send arp request and didn't get anything back.
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.
anyone ever tried to inject packets on win7?
to avoid more questions:
all network preferences are ok, no physical problems. 
the code is written right, it works on XP.

  Can you please try connecting the two computers directly with an ethernet cable and see what happens?

  Have a nice day

  I can not send packets from win7, it has 2 network interfaces, ethernet with direct connection to adsl modem, and wifi connection to notebook.
  The packets i send from win7 are visible in wireshark, but actually they do not transmiting over network. both devices (modem and notebook do not receive them).

    Are you saying that the issue happens when transmitting from either a wired host (with an ethernet connection) or a wireless card?

    One host directly through the cable, and the second via WIFI.
