I just create and OS deployment with fuel with 1 controller and 1 compute node. I can launch an instance (oddly enough Admin account can't but another account can) and it boots correctly. Within the Cirros instance I can ping my public gateway, and the internet ( However, I cannot ping the instances public floating IP (e.g. from my laptop ( The firewall/security within Openstack is accepting everything. I can even ping my laptop from Cirros (the openstack instance). I can login to the router namespaces on the controller and can ping stuff without an issue. Not sure where to look from here on debugging this issue.

I realize this topic seems to come up a lot and I tried those suggestions but none of them worked. Any suggestions?

Add ICMP rules anyway and see what happens.

I'll try that. I did explicitly add the rule to allow SSH and could not SSH either.

@rl_person I explicitly added the ICMP and SSH rules to the default security group (instances is part of the default group) and it did not work. However, when I added the rules to the entire CIDR public range I was able to get to the instances public ip. Any reason security group would not work?

In my env was working well and without reason my the floating ip cannot ping and was solved restarting the neutron-l3-agent in all compute nodes.

systemctl restart neutron-l3-agent
