(physical port P3). The opt interface is the only default interface that you can
change to be part of a different zone. The opt interface belongs to the OPT zone
by default. The OPT zone is a separate zone and you can configure a different
set of security policies for it.

192.168.1.254 range.
• The WLAN zone contains the ext-wlan interface (physical port P6). This is a
second protected zone for connecting wireless access points. The ext-wlan
interface uses private IP address 10.59.0.1 and the connected devices use IP
addresses in the 10.59.0.2 to 10.59.0.254 range.
• The DMZ zone contains the dmz interface (physical port P7). The DMZ zone has
servers that are available to the public. The dmz interface uses private IP
address 192.168.3.1 and the connected devices use private IP addresses in the
