[Winpcap-users] winpcap3 and winpcap4 bridge

First of all, please don't bash if I make any mistakes, since I'm new
with the mailing list concept. If there is such a thing as a web
interface, I'd gladly use that. But for now, I'll just keep waiting for
my email client to yell.
Anyway. My problem is as follows: I use ISIS VSM simulator, which in
turn uses winPcap. I develop Ethernet applications for microcontrollers.
This simulator can directly inject packets into my networks using
winPcap, but it uses version 4.
I need to craft this packets somehow. Of course, I could always do it by
hand, but I might make a mistake, and I'll have to compute three bloody
checksums for a single UDP frame (ethernet, ip headers, udp checksum). I
have a program to do this, nemesis. It's a nice thing this can also
inject the packet into my network, so I can see how everything should
react when the simulator would send it. However, nemesis doesn't work
with winPcap4, it needs winPcap3. It's really awkward to keep doing
Is there some kind of bridge or compatibility layer between the two? If
I use ISIS with 3, it crashes. If I uses nemesis with 4, I get an error
for missing entry point in packet.dll.
