Traceroute not working on linux

strangegopher

traceroute does not work. the output is like this:

traceroute to google.com (209.85.231.104), 30 hops max, 52 byte packets
1  * * *
2  * * *
3  * * *
4  * * *

Any idea why? It was working fine few days ago but now does not work.
I am able to traceroute directly on pfsense but I can't do traceroute from my laptop to any device inside or outside my network.

edit: traceroute with tcp (-T) and icmp (-I) works but only gives one hop. but traceroute with udp (-U)/default does not work.
edit2: I disabled firewall on my laptop with no success.

It works for me. I'm running openSUSE 42.3.

Works with a Lubuntu client.

You don't happen to do something strange and created a rule which blocks ICMP?

Not really.

It seems like issue with my laptop itself. I ran a kali virtual machine in bridge mode and did traceroute after restarting my router and switch and this is the output I got:

Not sure why its only giving me one ip address. But local ip address traceroute does not work at all.
I get proper output when I do traceroute on pfsense itself.

Found the issue. It was fq_codel.
