Proxmox 1public ip setup 2016

[zustudios]

I'm trying to setup muitiple webservers that use the same ports. How do I setup my proxmox /etc/network/interfaces ? How do I set up port fowarding?

eth0 , vmbr0 , vmbr1
I want to set up 3 machines:
server1.example.com

server2.example.com

https://www.howtoforge.com/how-to-r...and-secondary-with-ispconfig-3-debian-squeeze

and windows 7

This is how my network is set up. will this work under 1 public ip?
