syed opened a new pull request #2221: [CLOUDSTACK-10030] - Make publicips reachable inside VPC
URL: https://github.com/apache/cloudstack/pull/2221
 
 
   If a public IP is assigned to a VPC, a VM running inside that VPC cannot ping that public IP. This is due to the IPtables Nat rules set in such a way that drop any requests to the public IP from internal interfaces. I am fixing this so that internal hosts can also reach the public IP.
   
   Reproduction:
   
   Create a VPC
   Create a network inside the VPC
   Allocate a public IP
   Create a VM in the network
   Create a port forwarding rule enabling ICMP
   ping the public IP inside the VM (this will fail)
