It shouldn't affect traceroutes. If it did the TOTD would never have been
But it obviously affects traceroutes outside of the network, which is what
I was referring to above. Tracerouting outside of our network is just as
important as inside.

Presumably the private IP addresses would be fully routed within your
network but filtered at the borders.
