Does it make sense use VPN to provide wireless security in my environment ?
I mean, all our sites are interconnected through Fiber to our Main Office
router.

We do have hundreds of Cisco AP and we currently deploying LEAP to provide
wireless security.
Now a co-worker is saying that VPN is a good option to provide wireless
security and would save us work, since we don't need to setup a protocol
like LEAP.

For me launching a VPN client to provide encryption is fine, but then people
in the parking lot is still going to be access IP addresses from our DHCP
servers and I think that is a security issue, right ?
