Public IP management.

Hi,

I have been playing with proxmox and stubbled on this guide which i found extremely useful.

I am just starting with one node at the moment, so i have just skipped past some of the clustering part.

I have succeeded in setting up a private subnet with openVPN and have created some VM with local IPs from the private subnet.

What i am struggling with is understanding how to safely bind or map public IPs to my local VMs ?

or

Is there a way to route independent (domain request like www.abcd.com) requests from my host proxmox instance proxmox IP) to the VM individually ?

Thanks
