I have a weird problem in CloudStack 4.11.2. And want to see if there is
any suggestion on how to debug / fix this issue.
I created a VPC network, with one guest network. I have added 32 VMs,
requested 32 public IPs, and setup static NAT to associate the IP to each
of the VM. These works without any issue. However, then I added one more
VM, and request 1 public IP. When I try to associate the public IP with
the VM, I get the error that it failed to enable the static NAT:

It seems that the virtual route has problem associating the 33rd static
NAT. We have tried CloudStack 4.9.3 and does not have this problem.
Is there any suggestion on what I should do?
Thanks
Ivan
