Layer 2 network to data centre from Sonicwall
Hi guys, I have a problem and need advice please. I currently have a LAN network on port X0 on the TZ400 SonicWall. The IP range is 192.168.1.0/255.255.254.0 On the LAN side I have two servers. One primary and one secondary. The primary replicate VM's to the Secondary. In the event of a primary server crash, I can boot up the VM's on the secondary server. We have done many tests and this just works fine. We now have a flat layer 2 networks available to a data center and we need to move the secondary server to the datacentre. The service provider stated that I am allowed to use any IP range on the Layer 2 network. Now my question. I am looking at the layer 2 network and thinking that I can just plug it into one of my network switches on the LAN side and I extend my LAN network to the datacentre, but then it will have no IP address or routing. If I plug the layer 2 network into my Sonicwall's X4 interface and give X4 and IP address in the same range as the X0 Subnet. Will the SonicWall allow the same subnets on two different X ports. If not how do I now allow traffic from 192.168.1.0/255.255.254.0 through X4 from the LAN on X0? I need the later 2 networks to the data center to be on the same subnet as the network on X0. So basically using the Layer 2 network as an extension of the LAN network. Any advice will be appreciated. Thank you.
