Huh.  That's wild.  I didn't know UDP was useful for such things.  I'd've
thought there'd have to be like a "tracerouted" listening to some UDP
port(s) for it to work that way, whereas I thought the TCP/IP stack was
responsible for responding to certain ICMP messages, and that ICMP's whole
reason for being was things like ping and traceroute (and lower-level
equivalents).

I see.  That explains why Russ Price and I were seeing different behavior
than Tom Eastep.  Presumably the solution, then, would be to open up some
"icmp" stuff in Shorewall, though I wouldn't hazard to guess what.

Personally it doesn't really bother me that the first hop of traceroute
always gets "* * *", now that I know it's to be expected.  (If the required
Shorewall rule to fix it were easy, however, I'd probably go ahead and do
so.)
