Traceroute is a protocol that can work with icmp or udp:
Windows - ICMP
Unix, Linux and IOS - UDP.
This means that, when you are running a connetivity test using traceroute, the results will different depending on the OS you are using. The reason is because icmp might be open in a firewall while UDP won't.
If you are using icmp traceroute, icmp will be open.
If you are using udp, the following udp ports must be open: 33434-33534
