Routed configuration question

[zoltanb]

If I have one public IP for the host and 4 more public IPs for the guest, by using routed configuration (as presented here: https://pve.proxmox.com/wiki/Network_Configuration), the guests will use their public IPs while accessing the internet or host's public IP?

How do I need to setup vmbr0 if the 4 additional public IPs are randomly allocated by the hosting provider? For example: 5.6.7.8, 7.8.9.10, 11.12.13.14, etc.?

I'm gonna say their traffic will be using their IP, routed via the main IP of the bridge on the host. Your host will be a router like any other.

If you can get MACs for your VM IPs, bridge networking is much simpler. You can even do dhcp if your provider supports it.
