vpn passthrough netscreen doesnt work

Got 3 offices, each one with a NCP secure gateway VPN. Two brand
office that connects to HQ. Thats works fine. But when the
roadwarriors that uses ncp enterprize client tries to connect, the
date wont pass the netscreen.

Ive configure VIP service, and policy to pass UDP 1701(L2TP) to our
VPN gateway, and as I said, site-site work, but roadwarrior-site
doesnt work. Anyone have any clue?
