Secure WLAN with IPsec ?

[Gandalf]

Hi,

I would like to secure my WLAN with IPsec, My setup:
pfSense is directly connected to the Internet, it has 2 subnets LAN: 192.168.1.0/24 and DMZ: 192.168.2.0/24.
On LAN I have a Linksys WRT45G connected as an Access Point (all firewall/DHCP etc disabled), I have WEP disabled (I don't see the point of having WEP while cracking it is so easy, and WAP sucks with linux), I only have MAC filtering ATM, I would like to use IPsec to be on the safe side, but I'm very Newbie at VPN tunneling etc…
I have looked at http://edain.de/wlan_protection.html This tuto covers having a tunnel for each PC but not in general, isn't there a way to have a General tunnel for all Wifi connected devices that knows that Pre-shared key?? if not then how to do it for each client in pfSense, same as that tuto or is there a better way??

Thanks

I suggest using WPA for your WLAN Clients. It's aes encrypted (like a vpn) and most wireless cards do the encryption in hardware so they won't require cpupower to get throughput.

or use the vpn ptpp server on youre pfsense server and the ptpp client on youre pc's
