I guess nessus uses the "normal" Traceroute of your platform.


No, it does not call any external command.

Nessus first runs a TCP traceroute, but if it does not get an answer
for some gateway, it switches to UDP, then tries ICMP.
As long as a protocol works, it sticks to it. As soon as a gateway is
missing, it tries the other protocols (e.g. from ICMP, it will switch
back to TCP or UDP). When 3 protocols fail in a row, the trace ends.

Said in another way, it tries really hard to get an answer for
firewalls or unreliable gateways. This probably explains why it finds
more gateways than the system traceroute.
