When you configure IP redirection for an SSID, the access point redirects all
packets sent from client devices associated to that SSID to a specific IP address.
IP redirection is used mainly on wireless LANs serving handheld devices that use
a central software application and are statically configured to communicate with
a specific IP address.
For example, the wireless LAN administrator at a retail store or warehouse can
configure IP redirection for its bar code scanners. They use the same scanner
application and send data to the same IP address.
You can redirect all packets from client devices associated by using an SSID or
redirect only packets directed to specific TCP or UDP ports (as defined in an
access control list). When you configure the access point to redirect only packets
addressed to specific ports, the access point redirects those packets from clients
and drops all other packets from clients by using the SSID.
TIP
This figure shows the processing flow that occurs when the access point receives
client packets from clients associated by using an IP-redirect SSID.

When you perform a ping test from the access point to a client device that is
associated by using an IP-redirect SSID, the response packets from the client
are redirected to the specified IP address and are not received by the access
point.
