Configuring the DMZ Interface
You can configure the DMZ interface in either Transparent Mode or NAT Mode:
•Transparent Mode enables the SonicWALL security appliance to bridge the DMZ subnet onto the WAN interface. It requires valid IP addresses for all computers connected to the DMZ interface on your network, but allows remote access to authenticated users. You can use the DMZ interface in Transparent mode for public servers and devices with static IP addresses you want visible outside your SonicWALL security
•NAT Mode translates the private IP addresses of devices connected to the DMZ interface to a sin- gle, static IP address.
