Let me rephrase, each VPN client will be in its own /32 subnet, i.e. one 
IP, but several clients/IP's can belong to an IKE. The SSG VPN server 
will take care of the routing for you. But you have to assign policies 
to each IKE to be able to communicate with the remote subnet/zones, be 
it ping or "Any" access. Hope it makes sense.
