problem</DIV>
<DIV><BR></DIV>
<DIV>Hello,<BR> I've currently
run into a problem related to transmitting packets over a PPP connection. From
what I've read about the capabilities of Winpcap, only receiving is supported
for PPP<BR>connections. Now I've downloaded the WinPcap source but I
haven't looked into it. Is adding this functionality an easy fix that perhaps
I can add myself? It so, where and how in the WinPcap source do I go about
doing it.<BR></DIV></BLOCKQUOTE>
<DIV><FONT face="Courier New">PPP capture uses a completely
different approach than normal adapters. We use the Microsoft Network
Monitor (NetMon) component to capture from PPP, and such component does not
support transmission.</FONT> </DIV><FONT face="Courier New"></FONT>

<DIV><BR>On the other hand, if adding this functionality will be a long
and difficult task, what other alternatives/fixes do I have to transmit my own
custom crafted TCP packets over a PPP connection?</DIV>
<DIV><FONT face="Courier New"></FONT> </DIV></BLOCKQUOTE>
<DIV><FONT face="Courier New">A protocol driver, similar to the WinPcap one but
with some modifications specific to PPP, should do the trick (I'm not
actually 100%). Consider that that managing PPP connections in a
protocol driver is a bit tricky as all the connections are aggregated into a
single adapter instance, and you need to take care of
multiplexing/demultiplexing the packets.</FONT></DIV><FONT
