I'm trying to setup a site to site vpn between a cisco device and a juniper ssg device. I have the juniper setup in L3 mode with routed interfaces. For some reason it is not getting past phase 1. I can ping the public ip of the other side fine. Here is one possible reason that phase 1 isn't getting established:

x.x.x.x is the interface ip of the juniper and y.y.y.y is the cisco interface ip. x.x.x.gw is the gateway address that the default route on the device is pointing to.

The cisco tac rep said that their device is sending packets fine but are not receiving any from the juniper device. From the output above, it looks like the packets from the juniper to the cisco are being dropped.
Can anyone help me out?
Thanks
