No network access on Proxmox containers

[Camelweb]

Hi all

Our company has a VPS service at Cloudzy.
It is a 12vCPU 32 GB RAM 750 GB Disk setup.
I have the main IP address and we also bought 4 additional floating IP's, intended for the VM's or LXC's.
Proxmox itself is working correctly, i have updated it and i am able to access it on SSH.
I think i have added right the floating IP's to the Proxmox setup, i can ping the IP's, but when i create a VM or LXC, i cannot make the network work on it.
I even opened a ticket at Cloudzy, and i got the following answer:

Hello,
Please note that the floating IPs can only be bridged to the network interface of the server itself, not directly to the container inside Proxmox. To allocate a floating IP to your container, you should configure the floating IPs on the server's network interface, and then use NAT networking to provide the Proxmox VM with internet access through that IP address.

I can provide any of the configuration files, but i need to know what needs to be masked, and what files should i attach.
Please help me to solve this problem

Hi,
there should be a Linux bridge created already, usually vmbr0, with your server's network interface already assigned as port. Just use this bridge for your VM/LXC and assign a floating IP for each of the VM/LXC.
Otherwise the documentation might help: https://pve.proxmox.com/pve-docs/pve-admin-guide.html#sysadmin_network_configuration
