1.1.6 IPSec VPN Support
A VPN ensures data privacy between two end points, even while using a communication medium
which is itself insecure (like the Internet). VPNs create a secure tunnel between two end points as if
they are directly connected over a secure connection. Traffic is secured using a robust IPSec
encryption technique.
You can get the safety of a VPN in a WLAN by hosting the VPN server at the access point, and the
VPN client software on the MU. For that reason, a VPN provides secure WLAN access to MUs. A VPN
solution was more common before 802.11i was introduced, but is not as common now, since 802.11i/
WPA2 is considered more secure.
For information on configuring VPN support, see Configuring VPN Tunnels on page 6-22. For
instructions on configuring a IPSec VPN tunnel using two access points, see Creating a VPN Tunnel
between Two Access Points on page 6-26.
