[Winpcap-users] winpcap3 and winpcap4 bridge

[izua richard]

Hey!
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 
uninstall4/install3/uninstall3/install4.

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.

Any ideas?
Thanks,
Richard
