Static NAT with multiple public interfaces uses wrong outgoing IP #4234
Description
ISSUE TYPE
- Bug Report
COMPONENT NAME
VR
CLOUDSTACK VERSION
4.13.1
CONFIGURATION
advanced networking
multiple public interfaces
OS / ENVIRONMENT
CentOS7 +KVM +Bridge
SUMMARY
When a VR has public IPs on multiple interfaces, a static NAT rule which is not on the first public interface will have outgoing traffic originating from the Source NAT IP
Same as #3168 fault description
However, my mangle / PREROUTING firewall rule status is already NEW MARK set 0x67
STEPS TO REPRODUCE
1. Assign public IP from different subnet to VR (so that VR gets eth3 created).
2. Deploy a VM on this network
3. Create static NAT rule for this new public IP to the new VM
4. Run curl ip.sb inside the VM
EXPECTED RESULTS
Output should be the Static NAT IP
ACTUAL RESULTS
Output is the Source NAT IP
