How to use OpenVPN and multiple IPs on a VPS?

Question

openvpn

Good afternoon.
The situation is as follows:
There is a KVM VPS with CentOS 7 on board.
Took with one more additional IP.
Installed OpenVPN, configured the config, launched it. The client successfully connected to IP1 and had IP1 at the output, then connected to IP2 and had IP2 at the output. Everything as I wanted. Decided to add 3 more IP addresses to the server, added.
Created eth0:1 eth0:2 eth0:3 configs in /etc/sysconfig/network-scripts/ respectively for new IPs.
And now, for some reason, when I connect to OpenVPN via any of the 5 IPs, I always have 1 IP at the output, which is eth0 in the main config
Tell me where I broke everything and how to return this correspondence - to which IP I connect, this and the output as external ?
