Hi Rick,
Thanks for your reply. I'm new to VMware cloud.
Regarding the below KB, Could you explain in more detail?
As stated in the KB: "VMC also uses this IP range between internal routing components it will create a conflict."
Inside my subscription, If my network (100.64.x) segment needs to communicate outside (internet) or AWS backbone it should be NAtted using public ip.
In such a case how the internal routing components will create conflict.
