I used the following article to get traceroute working on my FreeBSD box
(refer Page 3):

http://www.onlamp.com/pub/a/bsd/2001/06/01/FreeBSD_Basics.html

Also, because I was blocking outbound UDP, I had to enable a range of UDP
ports. Traceroute's man page had the relevant range. I'm between installs
and away from my notes at the moment so I can't give you the specifics, sorry.

Hope that helps,

Adrian.
