Machine B seems OK. > *Machine A:* > > :~/rohc-1.2.0# ip -4 addr > 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 16436 qdisc noqueue > inet 127.0.0.1/8 scope host lo > 2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast > qlen 100 > inet 137.158.131.84/27 brd 137.158.131.95 scope global eth0 > 5: rohc0: <POINTOPOINT,MULTICAST,NOARP> mtu 1500 qdisc noop qlen 500 > inet 10.0.0.1/24 scope global rohc0 Machine A is not OK. The rohc0 interface is not UP and RUNNING, use the following command to fix that: # ip link set rohc0 up > ~/rohc-1.2.0# ip -4 route > 137.158.131.64/27 dev eth0 proto kernel scope link src > 137.158.131.84 169.254.0.0/16 dev eth0 scope link metric 1000 > default via 137.158.131.65 dev eth0 The route toward network 10.0.0.0/24 is not present. It should be setup when the rohc0 interface will become UP and RUNNING. Please check that the route is present after running the 'ip link set rohc0 up' command. There is an additional thing that looks strange to me. The ping from machine A to machine B gets a TTL of 57. The ping from B to A gets a TTL of 63. Beside the fact they are different (is there different paths to go from one machine to the other in your network ?), it shows that you have at least one router between the 2 machines. They could be the root of the problem. Could you please test the tunnel tool with 2 machines on the same Ethernet link to see if it works ?
