Salut  Jean-Charles,

yep it's the address of the juniper.

> If it is the Juniper address it is normal that you see packets in clear but if it is a host address defined in your "lt85_to_centre" connection configuration, you may have to check the "leftsubnet=" line.

my connexion configuration is :

conn lt85_to_centre
        #
        #lt85
        #
        left=212.121.x.x
        leftsubnet=10.24.0.0/16
        leftnexthop=212.121.x.x
        #
        #destination
        #
        right=194.250.x.x

Okay :)

> Anyway... What is the original question ? :)

My question is how can i setup the connexion between my openswan box
and the juniper :) and why my config doesn't work :)
