Commit ff7527fc87656f734ddbe804a451c67423fecdea in branch refs/heads/4.2 from

CLOUDSTACK-4084 Fixed the static nat vm ip address in public ip address table
in external network gc
In external network after network GC the network n/w cidr changes.
In this case the static nat enable vm ip also chagnes. So updated the new
vm ip address in user_ip_address table.

> default.)
> Components: Network Controller
> Affects Versions: 4.2.0

> Steps to reproduce:
> 1. Have latest CloudStack setup with at least 1 adv zone using KVM hosts
> 2. Make sure network.gc.interval and wait are set to "100" seconds
> 3. Have at least one network offering of type "isolated" and with all
> services enabled where LB is provided by NS and other services are provided
> by VR.

> (iii) Initially for the above network the CIDR given to it is : 10.0.0.0/20
> 5. Make sure all the above rules are working. Now, power off the userVM and
> wait till network GC
> Observations:
> (i) After GC, the above network got 10.0.80.0/20 as CIDR and everything
> worked fine without issues except StatiNat rule.
> (ii) When I tried to ssh to 10.147.44.64 then it failed. check the VR for the
> rule and found that it is still programming staticNat with old guest ip i.e.
> 10.0.0.62 instead of new guest ip i.e. 10.0.80.62/20.
> Note : PF went fine without any issues.
