CLOUDSTACK-2728: 41-42 DB upgrade: add step to upgrade system templates
CLOUDSTACK-2812: Static NAT rules are created with same name and Destination IP Pool for each Public IP with which only one instance is reachable with both Static NATed IP's
For static NAT rule an IP pool gets created in VNMC. In order to make the pool name unique the rule id is appended. Since static NAT rules are not stored in CS db. like PF/FW rules, the id was always set to 0.
As a result the pool was always getting overridden everytime a static NAT rule is created. Fixed it by appending the public IP address id along with a character indicating that the pool is used for static NAT rule to the pool name.
