One-to-One NAT with different subnet on Sonicwall
Just picked up a client with a bonded T1 through Time Warner and have run into a configuration that I didn't know was possible, just wanted to find out why or how this is possible.
Firewall is a Sonicwall Pro 2040.
Their primary external IP is (changed) 72.201.205.172 with a /30 subnet, with an internal NAT 10.24.1.0/24.
There are also one-to-one NAT entries for several servers. Their external IPs are 205.75.34.146-151. And the entries work.
Should this be possible? Is this something that the ISP has to set up to be possible? Is there a good overview of one-to-one NAT that I could read to understand what's going on?

The WAN Interface will only show the primary IP and subnet. In order to see any other networks on an interface, view the ARP entries to see if another network range has been attached to the X1 interface. (sub interfaces, like vlans, will show on the interfaces page)
Thanks for the points!
