[Openswan Users] Openswan architecture (openswan, windows, netscreen )

[Didine]

Hello,
I'm in the process of installing openswan in the following architecture :

192.168.0.10(win xp) (maybe TauVPN)
||
212.z.z.z (router)
||
(internet)
||
212.x.x.x (netscreen)====10.10.0.0/16
||
 (internet)
 ||
212.y.y.y (openswan)

I want to be able to connect from the winXP box and OpenSWan boxes to
the netscreen subnet.
I have some questions :
* Can openswan connect to netscreen ?
* Can my WinXP box connect directly to the netscreen subnet ?

Any suggestions are welcome :)
Thks a lot for ur help.
