DeepthiMachiraju created CLOUDSTACK-9969:
--------------------------------------------
Summary: Public IP acquired from additional public ranges which
is static nat enabled is set to true post releasing the IP in VPC VR.
Key: CLOUDSTACK-9969
URL: https://issues.apache.org/jira/browse/CLOUDSTACK-9969
Project: CloudStack
Issue Type: Bug
Security Level: Public (Anyone can view this level - this is the default.)
Components: Virtual Router, VPC
Affects Versions: 4.10.0.0
Reporter: DeepthiMachiraju
Fix For: 4.10.0.0
Attachments: cloud.log, management-server.log
- Create VPC and create multiple tiers within VPC.
- Acquire IP from additional Public Range and ENable static nat on the IP.
============== rules created after the above step =============================
- Here eth4 : 10.x.203 , 10.x.204 are the acquired ip
- 10.147.52.203 is static nat enabled.

==============================================
- Both the acquired IP's are released from the UI.
============ logs post releasing =========================
- eth4 10.147.52.203 is still set to true in ips.json file.
- IPtables are cleaned up.

- BUt when a new IP is acquired from the same subnet and a rule is configured
for that IP , the previous [203] IP which was deleted but set to true in
IPs.json file is now observed in interfaces and iptables .
