Description

On a VPC, releasing a public IP that had Port Forwarding does not remove configuration of the public IP on the VR configs (/etc/cloudstack/forwardingrules.json, /etc/cloudstack/ips.json)

So, when this IP is reassign to another VPC, it cause arp table issues on switches, because 2 MAC try to own this IP from 2 different VRs. the IP on the old VR is not pignable but the switches arp table get updated every time the previous VR have configuration changes.
