Yup, you need to configure an “address pair” for the floating IP.  This isn’t specifically a security groups thing, but it will allow traffic to the floating IP to pass into the VM to which it is associated.

Under the covers, it’s implemented similarly to security groups, but is not directly a security groups function.

Subject: [Openstack-operators] [Neutron]floatingip with security group

I create a VM with a default security group , then I create and associate a floating ip with this VM.
But I can't connect the floating ip, I check the security group, and I think it's the sg problem. I add a rule in default sg, and then I can connect the floating ip.

When I create a floating ip , Does I have to add a rule in security group to allow the ip for ingress ??
