Description changed to:
Sorry again for my ignorance, but I'm trying to understand the iprohc
basic operation.  I'm not sure exactly how this works verse how say the
original non production udp tunnel worked.

I have a server running on one machine, and a client running on another
machine.  The server and the client appear to be connected, the log
files indicate that they have exchanged certificates properly.  It is at
this point that I do not fully understand the system.

ifconfig on both machines show me that the server has created an
interface "tun_ipip" and that the client has started an interface of my
naming.  The server interface has the same ipaddress associated with it
as eth0.  The client interface has a new ipaddress associated with it.

The route command for both machines shows that all traffic on the subnet
is to be routed to both eth0 and the new interface.

So how do I send compressed traffic at this point.  Will it be all
traffic between the two machines?  Is it only traffic that is sent to
this new ipaddress on the client? Or, do I need to create my own routes
that force traffic to these new interfaces in order to use the system.

client ifconfig and
server ifconfig:
