Or IPSec alone. If you are not concerned with bandwidth issues from
wardrivers using your wireless network to access the outside world then
IPSec alone is enough to secure all your network data. A side benefit is
that visitors can use the network without network credentials to see the
outside world, but the internal network traffic will be beyond their
ability to watch.
