Configure Virtual Machine Internet Connection for a Server set up with Proxmox Virtualization

Hello Freelancers, We have recently purchased a large new server from So You Start - Intel Xeon W3530 48 GB. We have set it up and installed Proxmox Virtualization software - and created two virtual machines. The unit has a main IP address and we have added 2 additional IP addresses one for each virtual machine. We have been unable to get the two virtual machines to access the internet. So apparently we are just not familiar with the proper settings. Looking for a freelancer to access our server, and properly assign the IP addresses to the Virtual Machines, so that they can connect to the net. When applying, please mention your experiences for Proxmox Virtualization or you will not be considered for the position. Thank you!
