Question pertaining to Use of same public IP for static NAT, PF and LB in VPC

[Chandan Purushothama <Ch...@citrix.com>]

I referred to the Feature Information present at https://issues.apache.org/jira/browse/CLOUDSTACK-756

I faintly remember that we intentionally placed a requirement for a Public IP to be used for only one service in a VPC in the earlier release. One reason might be due to technical challenges that might arise due to different service provides present in a VPC (For Ex: Load Balancing can be done by an external device while other services are taken care of by the VPC VR.) .

Can anyone help me understand the possible technical limitations of this feature when VR is the all-services provider of the VPC? I am trying to figure out the cases that needs to be tested for this feature.

Thank you,
Chandan.

1. You cannot upgrade to an offering which uses multiple devices to offer
the same services
2. There are port-level conflicts that need to be tested: e.g., LB on port
80 along with PF on the same port, static NAT + PF etc
