My attempts to traceroute get stomped by my ipf configuration:

% traceroute

@150:4 b,33099 ->,33435 PR udp len 20 10240 

Unfortunately this seems to be a udp packet from a random port to a
random port - and I don't want the filters open that far.  I presume the
destination port is really irrelevant and maybe port 9 (discard) would
be more appropriate?
