Sonicwall Wireless Firewalling - SonicWALL SonicPoint ACe Getting Started Manual

SonicWall wireless firewalling
When a wireless device uses a SonicWall SonicPoint ACe
wireless access point to communicate with a wireless device
on another subnet or on a completely different network, traffic
between the devices is forced to traverse the SonicWall
network security appliance. This traversal enables security
services to be enforced by SonicOS.
Standard practice for wireless firewalling (where one wireless
client is communicating with another) bypasses many of the
critical security services. The following illustration shows the
standard practice for wireless firewalling.

Many security products on the market share this potential
vulnerability when two users connected by a common hub or
wireless access point wish to exchange data.
SonicWall addresses this security shortcoming by managing
the SonicPoint access points from the network security
appliance. This allows complete control of the wireless space,
including zone enforcement of security services and complete
firewalling capabilities.
