I'm not 100% sure whether it is the same. They could also have implemented MAC address security per switch port.

Any info from OVH staff on this. Please, pretty please

I had a look at the description and I don't think it is related. What they seem to be doing is blocking IP Addresses that are not assigned to a server to prevent spoofing. With Microsoft NLB you have one main IP address for the NLB cluster, additional virtual MAC addresses per server and dedicated IP addresses.

The project I'm working on will require initially 3 to 5 servers but could quickly go up to +20 servers. I therefore need to know whether Microsoft NLB is supported. I can test this for OVH if they want, but I'm not going to rent servers in order to do the tests.

I would like a confirmation from OVH staff that it is supported. I've been waiting to launch a major project involving multiple servers joined in a Microsoft NLB cluster.

That is something we all been waiting for, so we can use bridge mode for any kind of VT software.
Means another MAC will not be kicked out of the switch port.

Hi,

I read somewhere that the network security was (will be) changed to provide better support virtualistation. Does this mean that Microsoft Network Load Balancing will work as well? Will it be possible to use virtual mac addresses?

Thanks,

Peter
