Allow public IP acquisition without Source NAT #13081
Description
Allow public IP acquisition without Source NAT in Isolated Networks with Static NAT
ISSUE TYPE
- Improvement Request
COMPONENT NAME
CLOUDSTACK VERSION
4.20.3
SUMMARY
In an isolated network without Source NAT, it is not possible to add a public IP address when Static NAT is enabled.
Error:
Failed to acquire IP.
In zone of type Advanced ip address can be associated only to the network of guest type Isolated with the SourceNat enabled
It would be useful to have this capability, since Source NAT reserves a separate public IP address for itself. In scenarios where all VMs are expected to use Static NAT, the Source NAT IP remains idle and unused.
STEPS TO REPRODUCE
- Create network offering for guest isolated network
- Enable Static NAT in the offering
- Create an isolated network using the created offering
- Add a public IP address
