[Didier Barvaux <didier@xxxxxxxxxxx>]

Kimo,

Sorry for the late answer. I was busy with my everyday life and job...

In your 2nd test, you are using the overlapping IP ranges for:
 * the network that interconnects the 2 test machines
   (192.168.0.0/24)
 * the IP/ROHC network (192.68.0.0/16).

Please update your iprohc_server.conf file with a different network.
For example:
  ipaddr: 192.168.1.1/24

Regards,
Didier
