It has to do w/ how the router handles NAT and imcp packets. I'm sure
there's a way to play w/ your NAT rules to get traceroute to work correctly.

Hmm...  is there any reason you want to run your clients DHCP? It's fine if
you have a large network w/ lots of clients and DNS but if it's just your
home machine, I'd just set you network info statically. You'll end up w/
less head aches in the long run IMHO.
