	I did as asked and it looks like the right packets are being seen.

	I think this is a problem with name resolution.  I'm able to 
successfully ping yahoo from the Mac if I use there IP address.  There 
is a spot in the TCP/IP part of the Network setup that asks for DNS 
servers or optionally search domain.  Should I add something there?  
I've tried adding my DNS servers that I use on the NetBSD box, but that 
doesn't work.  
	I think the solution is close.  I'm going to look around on Apple's 
site for some more documentation.  It's like OSX wants to be like BSD, 
but it's just not there yet :))
