Hi All, I have two tenants and limited number of Floating IP's. In general Floating IP is working for me unless i try to reuse IP previously assigned to one tenant in another :(

Here are the details:

I've assigned IP 132.227.62.97 to VM1 to admin tenant, and it was working fine;

I've unassigned it from VM1 and I've deleted it with command:

nova floating-ip-delete 132.227.62.97

... so it becomes unused.

Then in other tenant I've assigned it to VM radotestvm which is running on compute0.

While I'm trying to ping this public IP I get request timeout:

PING 132.227.62.97 (132.227.62.97): 56 data bytes
Request timeout for icmp_seq 0
Request timeout for icmp_seq 1

I was checking what happen on compute0 and it seems that packet is visible on it:

[root@compute0 ~]# tcpdump -i qvoc05de119-4b -vvvv
tcpdump: WARNING: qvoc05de119-4b: no IPv4 address assigned

^C

but I don't see it on my VM :( (I did tcpdump on it and it is empty)

Everything works fine while I'm pinging VM radotestvm from other VM that is part of the same tenant...

Any ideas why packets are not delivered to radotestvm?

I'm runing Juno on Centos 7.

Answering my own question: the issue was related to security groups, I've updated the rules and it is working now... :)
