Hey all,

I have a system with Proxmox VE 1.9 on which are 3 running virtual machines are configured. They are connected to the internet with bridged networking with an own static IP.

But I have problems creating an internal network so that the VMs can communicate in a private network. For this I added a network adapter to every VM which is connected to vmbr1. I tried to configure the IP static with the /etc/network/interfaces inside of the VM. But the problem now is that the VMs can not communicate. My actually network configuration for the second card (eth1) looks like this:

iface eth1 inet static
address 10.8.0.1
netmask 255.255.255.255
gateway IPOFTHEHOST (but I am not sure if this is correct)

So can someone tell me how I can configure an internal network for the VMs?

BEST REGARDS!

P.S. Sorry for the bad english
