Not really. Traceroute works be setting the hop count of an IP packet
very low so that it gets an ICMP error message back from each router along
the way. You might be able to set things up to hide your internal network
by not changing the hop count when packets pass through your routers,
but that's it. You can do this with FreeBSD, but I can't seem to find
the option at the moment.
