I don't have a canned solution, but I've had good luck testing with
nmap (-S and -e are relevant) while running tcpdump (and filtering for
the protocols/ports) on a remote host. I can happily report that
someplace upstream of my home connection is doing some filtering --
nice. I still need to test at work.
