Has anyone successfully setup FreeS/WAN and if so can you provide some help?

I've been trying to get FreeS/WAN setup for the past 6 months and have not 
been able to get it to work.  I've read, re-read, re-read and again re-read 
the documentation included with the software and on their site but just 
cannot get it to work.

Here is what I am trying to do.  I've got a local network with a dedicated 
Linux firewall to the Internet.  I've also got a WiFi access point 
connected to the firewall and my laptop can use the firewall's services 
over the WiFi network but I wan't to use IPSec to encrypt ALL traffic to 
the firewall.

I'm using the FreeS/WAN 1.98b Gentoo ebuild on both machines and have tried 
opportunistic encryption and "road warrior" remote access configurations.  
Here is a layout of my network.

Internet - ppp0                       local network - eth0 - 192.168.1.0/24
