Feature overview

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.
