Demo steps required to expose a VM to public internet
|
|
1. Request a public IP address
|

2. Add a firewall rule on compute gateway to access to the VM
|
|
3. Create a NAT rule to forward traffic from public IP to private IP

Sample Prerequisites:
|

- A VM deployed inside the SDDC with private IP address
