[ubuntu] How to sort out ONE fixed IP serving several VMs

Hi all,

Host Ubuntu 14.04 desktop
VMs Ubuntu 14.04 desktop/server edition
VirtualBox

I have several websites running on VMs, each with its own domain/subdomain and internal IP address. But I have only one Fixed IP. Please advise how set up their static IP so that they can be evoked on Internet?

Does following document help?
VirtualBox: Configuring Static IPs for VMs

Thanks in advance
