I am trying to have iptables pick out traceroute packets. Windows uses 
ICMP for it's traceroute, so I use this:

iptables -t filter -A INPUT -p icmp -s 0/0 -d 10.0.0.1 --icmp-type 
time-exceeded -j QUEUE

Linux, however, uses both ICMP and UDP... How can I tell iptables to 
look for UDP traceroute packets?
