I am trying to set up an ipsec tunnel between our ASA 5505 and a Juniper ssg5. The tunnel is up and running, but I cannot get any data through it.

The local network I am on is 172.16.1.0 and the remote is 192.168.70.0. But I cannot ping anything on their netowork. I receive a "Phase 2 OK" when I set up the ipsec.

I think this is the part of the config that is applicable. It seems like the data is not routed through the tunnel, but I am not sure...
