The situation is this: We have a class C network that is subnetted into two halves. Our internal network is on .1 - .128 and we use the other half (.129 - .256) for clients. The client half is subnetted further into smaller chunks based on client needs. We are replicating a VM from the client side to our ESX server on our internal side. The idea being if their production VM ever goes down we can bring up the replica and avoid prolonged downtime. Their VM is a web server, which means giving the replica a different IP address is not a viable option.
When I asked Veeam about this situation, they suggested:
"Add a vSwitch/port group to the host and assign the vSwitch to the same vLAN as the original production network. This will avoid the need to change IP schemes."
That sounds great if I knew what he meant. Does the above suggestion mean anything to anyone? Is there a way to add a vSwitch that uses the same gateway/mask as our client's production VM so it would match when the replica is powered up?
Any advice/guidance is appreciated. Thanks.
