Securing wireless client sessions with VPNs
Note The ability to secure wireless client sessions is intended for low-data-volume applications
like that of wireless POS terminals.
To secure wireless client sessions, create a VPN tunnel from the wireless client to the service
controller. The sample topology seen earlier serves as an example for the sample
configurations that follow. In this example, the service controller LAN port has an IP address
of 7.1.1.1, the APs are at 7.1.1.2 and 5.1.1.2, and the wireless POS are at 7.1.1.3 and 5.1.1.3.

Note
To use VPNs to secure wireless client sessions, configure an IPSec policy for this purpose, or
configure the L2TP server or PPTP server.
Wireless clients are typically assigned IP addresses from the VPN address pool. Configure
this first via Service Controller >> Network > Address allocation > VPN address pool.
See VPN address pool on page 12-6.
Note Wireless clients require VPN software that is configured to work with your VPN configuration
on the service controller.
