<DIV><FONT size=2>It's not possible with WinPcap. With WinPcap you can only
send/receive packets to/from the lower layer i.e. usually the network card. In
order to inject packets back to the IP stack you would probably need an NDIS
intermediate (IM) driver, or a virtual miniport.</FONT></DIV>

style="FONT-SIZE: 10pt; FONT-FAMILY: Arial">I’m trying to replay messages from
machines located on a VPN connection by spoofing their IP when sending the
packages. It works fins because we send the packages to our self and the
router/switch will return the message that we sent back to us. But I do not
want to rely on this and some packages are of multicast type so other machines
might get them and they have no valid route to the source IP. What I wonder is
if it is possible to generate a package only to our local machine but instead
create an incoming message instead of an outgoing. Is this possible?
