This is probably pretty basic, but I am having trouble pinging one compute instance from another.
Instances: Bare Metal, Availability Zone: nova.
I tried pinging with attaching a floating IP as well, but I still get: Destination Host Unreachable.
Has anyone faced this issue before?
Hi,
One thing to check on bare metal is the firewall:
https://chameleoncloud.readthedocs.io/en/latest/technical/networks/networks_basic.html#firewall
You may need to adjust the settings to allow any traffic between instances other than SSH.
You can verify that the firewall is allowing ping by checking:
sudo firewall-cmd --zone=public --list-icmp-blocks
If that comes back empty, ping should be permitted by the firewall. If that’s the case, I’d check that you can SSH to the instances and that there isn’t another network connectivity issues as well. Also, make sure to verify that all the instances are started on the same network (e.g. sharednet1).
