IPSEC Site-to-Site: Link UP no conection LAN to LAN (XG is not creating the route to the remote network)

Hey, everybody,
On an XG550, I have VPN links that connect, and where there is a connection between the XG and the remote LAN, but not from my LAN and remote LAN (the XG is not creating the route to the remote network).
To make it work, I had to enter the route manually from console.
system ipsec_route add net 192.168.36.0/255.255.255.0 tunnelname VPN_NAME.

Any idea :-p
