There are a couple of different ways to implement traceroute, and 
some may use IP protocols such as ICMP that do not use port numbers.

  However, the ones that *do* use, as I recall, 32768+666+n, where n 
gets incremented as necessary.  So if you're watching a traceroute go 
by, you're likely to be seeing port numbers of about 33300 or so.
