<font face="Calibri">Hi,<br>
<br>
our multicast-receiving application is based, since some years, on
WinPCap.<br>
<br>
We use it under Windows XP and Windows Server 2003, and it works
well for receiving multicast<br>
packets independently from their TTL (0, 1 or 2) (with WinPCap
4.0.2).<br>
<br>
The same application running on Seven (with WinPCap 4.1.2) is
unable to receive packets with TTL = 0<br>
(sent by another application on the same machine). It is clearly a
reception problem, because if we use<br>
standard socket code for receiving packets, we get them.<br>
If we set the TTL=1, we receive the packets.<br>
<br>
Any idea ?<br>
Should we modify something in our code in order to get them again
?<br>
<br>
Thanks a lot,<br>
Alberto.<br>
