Hint: try to use kernel >2.6.7
I set up a vpn connection once with an xp client behind NAT, and the openswan 
2.2.0 server. A connection couldn't have been established.
Then I compiled the 2.6.9 kernel - everything worked fine (with THE SAME 
config files as while tries with 2.6.7).
Maybe it was a lack of some option in the 2.6.7 kernel (but without NAT 
connections worked), but I had no problems with 2.6.9, so try to use this
