When a wireless device uses a SonicWall SonicPoint ACe wireless access point to communicate with a wireless device on anothersubnet 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.

• SonicWall SonicPoint ACe access points are centrally managed by SonicWall network security appliances running the following versions of SonicOS:

• SonicOS 5.9.1.6 or a higher 5.9 release

• SonicOS 6.2.5.1 or higher

• Use the supplied power adaptor or an 802.3at compliant PoE injector or a PoE switch capable of providing 25 watts of power to each SonicPoint ACe.

• An active Internet connection is required for your firewall to download the latest SonicPoint firmware.

• 802.11ac wireless hardware requires more bandwidth than a single (or even dual) 10/100 Ethernet connection can handle. Gigabit Ethernet connectivity between the WLAN and the LAN is required to take full advantage of 802.11ac speed.
