Interface X0,
Interface X1, public IP from ISP
Interface X5, <--- this is what I need to configure

Behind X0, is our production LAN. Now we  need to create the same network ( behind X5. Sonicwall did not allow me to do this, the error said overlapping IP range.

How can I work around this?

Please help!

PS - here is more info to help understand the situation
We are on a server migration project. We need to make a test network behind X5 that is exactly the same IP range as the production network behind X0

Without access to the hardware, I believe yes.
Simply put both ports into the same vlan.
Basically the internal ports are on a switch, but the rest of the device is a router.
