Cannot ping MME from another PC

[ngonimombeshora]

Good day everyone!
I have been following the latest setup instructions for epc-fed and I cannot ping mme container from another machine connected via ethernet, (this machine is meant to run the eNB). The whole epc is running perfectly and running the eNB on the same machine is working as well. But I wish to run the eNB on another PC as this is recommended.

I have created an IP route on the eNB machine as show(according to my environment )
sudo ip route add 192.168.61.0/24 via 192.168.18.197 dev bond0

and also setting
sudo sysctl net.ipv4.conf.all.forwarding = 1
sudo ip tables -P FORWARD ACCEPT

Can anyone please tell me if I am missing something?
I not too sure if I'm using the correct epc_docker_host_IP_address. How do I go around finding this?
