Actually, most 4.XX based TCP/IP implementations used on various
flavors of UNIX have options to the 'routed' command to print out
just the information you are talking about.  All packets received
by routed (and those sent out) are printed.

I don't have the man page handy, but on System V I have used the -t or
log option to output this information.  This has proved to be a very
useful debugging tool on networks with many routers exchaning info.
