Usually you need a NAT rule from your host to the OAM IP. For example a nat rule like this: host:1022 -> OAM-IP:22

From outside: ssh -p 1022 sysadmin@host

But not sure what NAT rules are required, to access it from outside the Host machine. * Below is my deployment.

But still could not see packet reaching to the controller. Any suggestion would be very helpful. Thanks, Ankush
