The rohctunnel application fails to send UDP packets on your network
(see the "write_to_udp failed" error message in the logs). The other
system receives nothing, that's why it prints no stats.

Maybe the local address 192.168.1.4 is not affected to the underlying
eth0 interface ? Please, post the result of the following commands
(run them as root):
  # ip -4 addr
  # ip -4 route
