IPsec over a wireless network to a W2K or Windows XP client?

Is it possible to set up a Windows 2000 or Windows XP client to communicate with an OpenBSD system using IPsec, and pass all traffic over the encrypted link? I'm asking because I'd like to replace WEP with IPsec on my wireless network, but everything I've read suggests that Windows will only encrypt traffic to the other host or its subnet, but not other hosts via the gateway.

Can this be don at all? I know that it can be done from one OpenBSD system to another; the page at http://rt.fm/~jcs/ipsec_wep.phtml explains that well. Moreover,
http://www.cs.umd.edu/users/mvanopst/xp2obsd.pdf shows how to get Windows XP to communicate with OpenBSD over IPsec, so is there any way to combine these two to get wireless network security using IPsec from Windows 2000 or XP to an OpenBSD gateway?
