I have 2 machines (both ubuntu) connected through a network switch. Please see the picture below for the details on hostnames and ip address. So the two machines are called ubuntu and manifold2. On ubuntu I am running a docker container with hostname happy_go. I need each machine to be able to ping to other machine. I know this can be accomplished with docker port forwarding. But that will not work for me.
Currently, of the 3 ping pairs, the pair that doesn't work is ping from manifold2 to happy_go. On manifold2 I tried to add a static route
sudo ip route add 172.17.0.0/24 via 192.168.2.199 dev eth0
Still no luck, I believe something need to be done on the host ubuntu. Help appreciated.

Is Ubuntu set to forward packets for 172.17.0.0 to docker? I.e., is the device set to a) be routing, and b) do you have an iptables rule to do so?
