What setups do you guys use to provide secure wireless networks to clients using windows notebooks, in a small business environment where security is paramount? I'm reading around and it looks like a WEP/TKIP/VPN combo is the way to go. Thing is, I've never played with TKIP, and I'm not sure what the better solutions are... are there simple hardware solutions that will do WEP/TKIP and IPSec VPNs for an office network? Or is it best to have a WEP/TKIP access point that is isolated and that routes through a VPN server (say a Win2k machine, or Linux if there are easy solutions) to login to the domain? How have you guys set this up?
