How to set up networking in Proxmox4.1 on Debian 8.2 with three extra ips?

Question

Debian

Hello.
There is a server in Hetzner. With 3 additional sp.
Help set up the network correctly.
All containers will be on openvz.
It should be like this:
Container1 - on 2x additional ip
Container2 and Container3 on the third additional ip.
In addition, it is necessary that gitlab and redmine stand in containers 2 and 3, respectively. It turns out it is necessary to correctly forward port 80 with one ip with different urls.
offtopic - found ready-made images for openvz for them. Can be used? Difficult to configure?
Help pliz, I need the text config /etc/network/interfaces and in the "pictures" network settings for containers.

Answer 1

in proxmox 4.1 there is no openvz
and in lxc the network works completely similar to kvm.
