It depends on which traceroute client you use. Most unix clients
use udp packet to traceroute, and thus it doesn't "work". You can
use traceroute -I for it to use ICMP packets, and it'll probably
go through.

On Windows, it uses ICMP by default (I think) but you'll have to check.

Subject: [FW1] Ping vs traceroute



Hi, Firwallers:

I have a firewall-1 that allows "ping" but not "traceroute". Is this a
normal expected behavior? Is the rule accepting "icmp" supposted to allow
both "piong" and "traceroute".
I am a little confused. I appreciate all your help to understand this
phenomena.
