Is the packet sent by another WinPcap-based application? Have a nice day GV

We use it under Windows XP and Windows Server 2003, and it works well for receiving multicast packets independently from their TTL (0, 1 or 2) (with WinPCap 4.0.2). The same application running on Seven (with WinPCap 4.1.2) is unable to receive packets with TTL = 0 (sent by another application on the same machine). It is clearly a reception problem, because if we use standard socket code for receiving packets, we get them. If we set the TTL=1, we receive the packets. Any idea ? Should we modify something in our code in order to get them again ? Thanks a lot, Alberto. _______________________________________________ Winpcap-users mailing list [email protected] https://www.winpcap.org/mailman/listinfo/winpcap-users -------------------------------------------------------------------------------- _______________________________________________ Winpcap-users mailing list [email protected] https://www.winpcap.org/mailman/listinfo/winpcap-users
