Hi,

we're currently testing VDSmanager on Linux (Debian) with KVM. After setting up two VMs I noticed that it's possible to use any IP address within any VM, this way a customer might use more IPs than assigned or even worse customer A may take over the IP address of customer B. As far as I see this problem is caused because every VM belongs to a bridge witch connects to the network interface.
Are there any options to prevent this behavior?
