An Introduction to Zones and Interfaces
An Introduction to Zones and Interfaces
Zones split a network infrastructure into logical areas, each with
its own set of usage rules, security services, and policies. Most
networks include multiple definitions for zones, including those
for trusted, untrusted, public, encrypted, and wireless traffic.
Some basic (default) zone types include:
WAN
—Untrusted resources outside your local network.
LAN
—Trusted local network resources.f
WLAN
—Local wireless network resources originating from
SonicWALL wireless enabled appliances.
DMZ
—Local network assets that must be accessible from the
WAN zone (such as Web and FTP servers).
VPN
—Trusted endpoints in an otherwise untrusted zone, such
as the WAN.
The security features and settings that zones carry are
enforced by binding a zone to one or more physical interfaces
(such as, X0, X1, or X2) on the SonicWALL TZ 210 series
appliance.
The X1 and X0 interfaces are preconfigured as WAN and LAN
respectively. The remaining ports (X2-X6) are also LAN ports by
default, however, these ports can be configured to meet the
needs of your network, either by using basic zone types (WAN,
LAN, WLAN, DMZ, VPN) or configuring a custom zone type to
fit your network requirements (Gaming Console Zone, Wireless
Printer Zone, Wireless Ticket Scanner Zone, and more).
