Have you set sysctl net.inet.udp.blackhole=1 ?

If so, the FreeBSD box will drop the traceroute UDP probes and you'll
never see the host itself in traceroute output.

Eli,


Thank you. That was it. Changed net.inet.udp.blackhole=1 to net.inet.udp.blackhole=0 and traces work. I'll remember to read the man pages more closely too next time.
