Is it not possible to have the internal ip addresses of the tunnel 
machines talk with other internal addresses on the other side of the tunnel?
Example Set Up:
Packets from say 192.168.0.2 to 192.168.1.1 and back
(192.168.0.0/24 Lan)-(192.168.0.1 Internal)->(200.0.0.1 
Interface)===IPSEC TUNNEL===(200.0.0.2 Inteface)<-(192.168.1.1 
Internal)-(192.168.0.1/24 Lan)

I can see the packets from 192.168.0.2->192.168.1.1 under tcpdump of 
200.0.0.2 as a (ipip) Packet from 200.0.0.1->200.0.0.2 having 
192.168.0.2->192.168.1.1 listed but the packet just seems to disappear 
after that. It does not show up under lo0 or the internal interface.

Any Thoughts?

Thanks
Jon
