I can't reproduce the problem using your test case, either with  
Net::Pcap 0.16 on OSX, Net::Pcap 0.04 or 0.16 on Debian etch x86.

Is this patch reversed? The destination already looks like the  
version of fwknopd I downloaded (1.9.10).
If that's the case, I'm not sure to understand how this fixes the  
problem.
