In fact you can do it partially - windows tracert tool is based on ICMP  
and is easily preventable and routable. *nix traceroute and mtr are based  
on udp and all you can do is redirect all yer traffic over the other  
network, which is purely incorrect. The trick is that the user can point  
any port for udp connection and it still will work and trace. Sorry 4 the  
disappointment.
