Problem with traceroute

[scialuppa]

Hi, sorry for my bad english.
My problem is that I tried your "traceroute.py" example but it doesn't work.
He tells me that "Some routers are not responding" but if I ping from the cmd with various ttl, it works.

This problem may be related to your firewall. Can you try to deactivate it during the test and try again? I just tested on several virtual machines and it works correctly.

Your problem seems similar to the issue #7.

Thanks it worked.
I created a new rule coming into the firewall by enabling ICMPv4 protocol on all types.
