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 On Sun, 8 Nov 2015 13:49:15 -0600, Kimo Kandi <[email protected]> wrote: > Hi Didier, > > *Testing between two public cloud servers* > > I am testing between two public IP cloud servers.
