Hi Jayapal, In NuageVsp integration, we found that when NuageVsp plugin fails to enable a StaticNat in VPC, StaticNat does not get disassociated from tier. When I looked in to the code, I found that there is a field performedIpAssoc in enableStaticNat() method.
This field is initialized to false and not set to true after calling ipAddress = _ipAddrMgr.associateIPToGuestNetwork(ipId, networkId, false); So, this is value always false and when plugin fails _vpcMgr.unassignIPFromVpcNetwork(ip.getId(), networkId); is never called. But, in case of createPortForwardingRule(), similar variable is initialized but it is set to true after calling _ipAddrMgr.associateIPToGuestNetwork(). So, I tried the fix to set the flag to true after calling associateIPTOGuestNetwork() for staticNat and things are working as expected. When plugin fails, StaticNat gets disassociated from tier. Please let me know if I am missing something. Thanks, Suresh
