How to use traceroute on Linux behind a Vigor router

2009, June 5 - 12:46 — müzso
I've found the info at Draytek's LAN FAQ page.
In the Linux system, the traceroute function utilizes UDP packets that are blocked by Vigor routers for security concerns. Therefore, please kindly use the following command:
traceroute -I www.example.com
The -I switch forces traceroute to use ICMP ECHO (instead of the default UDP) packets for probes.
