Hi Ivan,

Consider pasting a log on pastebin and sending the link here.

If you are sure this is bug in 4.11, please raise an issue in Github: https://github.com/apache/cloudstack/issues

(worth checking global limits etc)

Kind regards

Subject: Failed to create the 33rd static nat

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
