ok.   i did the following:
	tcpdump -s 1518 -i fxp0 -w tcpdump.fxp1 &
	tcpdump -s 1518 -i fxp1 -w tcpdump.fxp1 &

then i did
	traceroute -Sn ftp.freebsd.org 
	ftp ftp.freebsd.org
	
from my client box.  after the above two commands finished i did the
following:
	tcpshow < tcpdump.txt >tcpshow.fxp0
	tcpshow < tcpdump.fxp1 > tcpshow.fxp1

the results are shown at
	http://www.nubisci.net/guru/tcpshow.fxp0  (public interface)
	http://www.nubisci.net/guru/tcpshow.fxp1  (private interface)

i'm still looking thru the output.  if anything stands out, i'd like to know

thanxs again  :) :) :)
