IPsec Server on Mac OS X Server 10.2.2?

I have (or, in some cases, will have very shortly) a basic small network, a desktop running Mac OS X server 10.2.2, a wireless access point (ethernet to wireless basically, nothing special), an iBook connecting via airport (OS X client 10.2.2) and a few other computers that will be getting 10.2.2 shortly. My desktop does a fine job of the basic DHCP/NAT/Apache and such, but I'm looking for something more - a VPN for my soon-to-be wireless network. I read the article on setting up a PPTP VPN server, but I'd like to have my server set up as a VPN server and forcing all data going through the ethernet port to be running on a VPN, preferably IPsec although PPTP is better than nothing. I read the article on setting up client to client IPsec tunnels, but because I have multiple computers at home and will have others (they will be running 10.2.2) visit on a fairly regular occasion, I want to have a server that provides for secure connections among all connected to it so I don't have to set up tons of client to client networks. I'm kind of looking for an arrangement like some people have with IPsec routers (and connect using VaporSec), except I really want to use my OS X server so that I have an all-in-one solution because I'd end up using it anyway and don't really want to buy even more stuff (wireless networking gear still isn't exactly cheap). Anybody have any thoughts? Galen blueandwhiteg3 at softhome dot net
